Many anxious patients and readers have called or written in the last week to ask about the health threats of radiation from the nuclear reactor meltdown in Japan. Here are answers that address your radiation questions, relating to both the reactor meltdown and general exposure in everyday life.

Q: How much does the radiation from Japan affect us in the U.S.?

Radioactivity from Japan has little impact on people in the U.S. Thus far, the news is reporting that the four reactors in partial meltdown spewed radiation as high as 500 meters or 1,640 feet, according to John Beddington, U.K.'s Chief science officer. Compare with the Chernobyl blast, which sent radioactive particles 30,000 feet high for months. While its true that reports from last week stated that minute radiation was detected in Sacramento, the amount was extremely minor -- one-millionth of what people get from natural background radiation, and health officials have assured us that it posed no threats to residents on the west coast of the United States.

You should avoid foods grown or raised near the fallout zone. Spinach and dairy produced within Japan's radioactive zone were found to have vastly elevated radioactivity. Radioactivity was also found in Pacific waters, just off the northern coast, near the nuclear plant. For now it would be wise to avoid seafood from Japanese waters. Over time, this radioactivity should dissipate as the reactor is cooled and ceases to spew particle ash and dust. Other than avoiding potentially contaminated food, there should be no concern for residents of the American continent.

Q: What is radiation? Is all radiation bad for our health?

There is a lot of misinformation about radiation that I would like to attempt to clarify. First of all, we live with radiation all around us: the sun and stars, rocks, earth, and even our own bones emit natural background radiation. Radiation also comes from television, smoke detectors, and microwave ovens. There are two types of radiation: electromagnetic and particle radiation.

Electromagnetic (EM) waves range from low energy to high energy. Low energy EM includes electrical, infrared, visible light, and ultraviolet (UV). These, with the exception of UV are relatively harmless and are sometimes even therapeutic, such as the far infrared wave. At the high energy end of EM are the diagnostic x-rays like gamma rays. As these are more powerful, exposure must be carefully monitored and limited. Particle radiationincludes electron, proton, and neutron beams produced from splitting unstable atoms from the likes of plutonium and uranium -- as in a nuclear reactor or bomb. High exposure to these types of radiation can cause cancer, genetic defects, and death. For example, a 2009 New York Academy of Sciences report on the death toll in the European fallout zone of the Chernobyl accident indicated that from 1986 to 2005 one million people died from genetic damage caused by the radioactive fallout, and numerous people suffered from thyroid cancer and leukemia.

Q: How much radiation exposure comes from medical diagnostic tests?

The annual average of acceptable exposure from natural and equipment radiation is approximately 1 millisieverts or mSv. To put this data in context: If the average acceptable exposure for each person is 1 mSv per year -- which, for illustrative purposes, we'll say is equal to 1 truckload -- then a simple chest x-ray is about 0.03 truckload. Said another way, it will take about 33 chest x-rays for an individual to reach their yearly radiation allowance. While a chest x-ray leaves you open to a small amount of radiation, an upper GI x-ray is equal to about 3 truckloads, and a CT scan is about 4 truckloads. These numbers may sound alarming, but if you had a condition requiring diagnostic imaging, to avoid it would be foolish and could delay treatments that could potentially save your life.

Q: What are some natural ways to reduce radiation load in the body?

Start by consuming more chlorophyll-rich foods, such as seaweed, kelp, blue-green algae, spirulina, and chlorella. These plants contain rich minerals, such as iodine, that bind up the receptors site in your thyroid, so that any radioactive iodine you are exposed to will be unable to harm your thyroid. Also, these foods contain selenium and other potent antioxidants that prevent destructive free radical activity and cancerous growth, as well as chelating agents that bind to toxins and eliminate them from your body. Also, eat antioxidant-rich foods of every color, especially cherries, blueberries, pomegranates, yams, and sweet potatoes. The variety of antioxidants found in these foods help your body to mop up free radicals and toxins. Drink 6 to 8 glasses of filtered water every day.

On the supplement front, increase your intake of vitamin C, E, and D to help antioxidant actions within your body. You may also take alpha lipoic acid, a nutrient that protects cells from radiation damage. Herbs like dandelion, peppermint, and chrysanthemum help the body detoxify. Undergoing a medically supervised detox program, like the Tao of Wellness Detox Retreat, can also support your body's cleansing function.

If you find yourself in the unlikely situation of excess radiation exposure, there are medically supervised chelation treatments using EDTA and other treatment methods.

I hope these answers help to clarify radiation's impact on your health and that you will use this information to live long, live strong and live happy.

Washington, D.C. - March 25, 2011 - Senator Tom Harkin (D-IA) today announced that the U.S. Department of Education's had awarded Iowa $2.9 million through the School Improvement Grants (SIG) program to turn around its persistently lowest achieving schools. Harkin is the Chairman of the Senate panel that funds education initiatives and the Senate Health, Education, Labor and Pensions (HELP) Committee.

"Investing in our children's future means directing resources where they are needed most.  When schools consistently have low graduation rates, it is important we focus our attention there," Harkin said.  "Today's funding is a step in the right direction.  It will help districts take the necessary steps to improve their weakest schools.   And, it could not have come at a better time for districts that are already struggling with tough budgeting decisions."

The $2.9 million made available to Iowa is being distributed by formula to the state and will then be competed out by the state to school districts. Iowa's application, which includes its list of persistently lowest-achieving schools, as defined by the state, can be found here.

School districts will apply to the state for the funds this spring.  When school districts apply, they must indicate that they will implement reforms to the lowest achieving schools.

Once schools receive SIG funds, they will be able to begin to spend them immediately to turn around schools this fall.  Iowa may apply to the Education Department for a waiver to allow them to spend funds over a three-year period.

Davenport, Iowa - March, 2011 - In remembrance of actress Elizabeth Taylor, the Figge will have on view their serigraph Liz Taylor by Andy Warhol.  This recognizable work will be on display in the museum lobby from Tuesday, March 29 through Sunday, April 10, 2011.

Andy Warhol, one of the leading Pop artists of the 1960s, produced numerous prints illustrating celebrities. This image of Elizabeth Taylor came from a movie studio publicity still. The serigraph created from the image is very similar to the popular series of prints of Marilyn Monroe. In both, he "paints" on their eye shadow and lipstick, emphasizing their beauty and memorable smiles. The Pop movement was a reaction against the huge scale and gestural, painterly qualities of Abstract Expressionism. Pop artists depended upon figural imagery and an impersonal approach to their subject matter. Artists such as Roy Lichtenstein, Robert Rauschenberg, and Jasper Johns began using recognizable images from consumer culture and images that would carry a strong emotional content.

This work is on view for free in the Figge lobby.  For museum hours or questions, contact the Figge at 563.326.7804 or visit www.figgeart.org.

Q.  In Washington, how much time do you spend meeting with Iowans, compared to work on the Senate floor, in committee meetings and in other discussions and work?

A.  When I'm in Washington, D.C., for Senate business, I meet with many Iowans who are visiting the nation's capital.  Because mornings are taken up by committee business, policy discussions and oftentimes Senate votes, I have appointments and conference calls with Iowans at least every Monday through Thursday, from 3 p.m. to 5 p.m., and any other time the schedule will allow.  Some of the Iowans I meet with in Washington are business groups such as chambers of commerce and trade associations; state, county and local officials; policy and issue advocates; student groups; and families on vacation.  The families and students often tour the Capitol and want to see a Senate office to learn more about the workings of the legislative branch of government.  Trade association members and others are usually interested in conveying their views about pieces of legislation or issues currently before Congress that affect their operations, including their ability to create and maintain jobs for Iowans, for example.

Q.  Do you meet with Iowans when you're in Iowa?

A.  If the Senate isn't in session, I'm almost always in Iowa.  I have visited each of Iowa's 99 counties at least once every year since I was first elected to the United States Senate in 1980.  My meetings with constituents include holding my own town meetings, speaking to service clubs and school groups, and touring and meeting with employees at local businesses and factories.  The 99-county tradition ensures that I get to every part of the state every year.  A lot of people know they can catch me then, or if they can't see me in person, they can at least read in the local paper that I spoke with their friends and neighbors who brought up issues of concern in the local community.  For information on upcoming meetings, please visit the events page of my website at http://grassley.senate.gov/events/index.cfm.  Iowans can also find out where I've already been this year by clicking on the interactive map located at http://grassley.senate.gov/iowa/interactive_map.cfm.

Q.  Why is it important for you to meet with Iowans?

A.  The seat I occupy in the United States Senate belongs to the people of Iowa, and I never forget that I work for them.  The honor of representing Iowans in Congress comes with the responsibility to be in touch with as many Iowans as I can, any way I can.  The essence of representative government is communication between those of us elected and our constituents.  There are a lot of ways to communicate.  In addition to face-to-face meetings, I communicate with Iowans using Twitter, Facebook, YouTube, Skype, a webcast, email, the telephone and postal mail.  Each of those options helps foster a stronger dialogue between me and the Iowans I represent.  Not everyone can get to a town meeting or visit Washington to tell me what's on their mind, so the more means of communication, the better.  Iowans can schedule a meeting with me in Washington or Iowa by visiting the scheduling page of my website, http://grassley.senate.gov/info/scheduling_requests.cfm.  It helps when requests are made with as much advance notice as possible.  My office also provides tour information and arrangements for popular tourist destinations, such as the Capitol and the White House.  Tour arrangements can be made by visiting http://grassley.senate.gov/info/tour_information.cfm.  Questions about meetings or tours also can be directed to my Washington office at (202) 224-3744.

But Animal Farmers Also Benefit from Biodiesel Production, Checkoff-Funded Study Shows

ST. LOUIS (March 25, 2011) - An updated, independent study funded by the United Soybean Board (USB) and soybean checkoff shows production of biodiesel continues to positively impact U.S. soybean farmers' on-farm profitability as well as the bottom lines of poultry and livestock farmers.

According to the study, the biodiesel industry's demand for U.S. soybean oil supported U.S. soybean prices by as much as 27 cents per bushel over the past five years, bringing U.S. soybean farmers an additional $2.7 billion in net returns.

The study also found good news for the U.S. soybean industry's biggest customer, the U.S. animal agriculture sector, which uses nearly 98 percent of the domestic supply of U.S. soybean meal. The increased demand for soybean oil resulted in a larger supply of U.S. soybean meal, decreasing feed prices paid by U.S. poultry, livestock and fish farmers by between $16 and $48 per ton in marketing years 2005-2009.

"As a soybean farmer, I'm thrilled to see that biodiesel puts this much extra money back in our pockets," says Jim Schriver, chair of USB's Domestic Marketing program and a soybean farmer from Montpelier, Ind. "But the study also shows that biodiesel helps us support our best customers by making feed more affordable. Lower feed prices help U.S. animal farmers stay competitive."

Soybean oil remains the dominant feedstock for biodiesel production, and the soybean checkoff funds a large portion of the research and promotion of biodiesel through the National Biodiesel Board. Much of this funding has been used on testing to prove biodiesel's performance, economic and environmental benefits.

Biodiesel improves fuel lubricity by 66 percent compared with petroleum diesel and performs similarly to petroleum diesel in terms of torque, horsepower, haulage rates and fuel mileage. Additionally, biodiesel bolsters the U.S. economy, supporting more than 20,000 jobs and generating more than $800 million in tax revenue as recently as 2009. And biodiesel can reduce greenhouse gas emissions by as much as 75 percent, which helps fight global warming.

These environmental benefits helped biodiesel qualify as the United States' first domestically produced advanced biofuel under the revised federal Renewable Fuel Standard. This requirement calls for the use of at least 800 million gallons of biodiesel this year and at least 1 billion gallons per year in 2012 and beyond.

The increased biodiesel production needed to meet this demand will be important. In 2006, the federal government required food containing trans fat to be labeled. Partially hydrogenated soybean oil creates trans fat, and the study shows biodiesel demand helped mask U.S. soybean oil demand losses after some food manufacturers switched to other oils to avoid trans-fat labeling. These declines in demand could continue over the next couple years.

Centrec Consulting Group, LLC, conducted the study with funding from USB's Domestic Marketing program. A summary of the study can be found on the soybean checkoff website at www.unitedsoybean.org.

USB is made up of 69 farmer-directors who oversee the investments of the soybean checkoff on behalf of all U.S. soybean farmers. Checkoff funds are invested in the areas of animal utilization, human utilization, industrial utilization, industry relations, market access and supply. As stipulated in the Soybean Promotion, Research and Consumer Information Act, USDA's Agricultural Marketing Service has oversight responsibilities for USB and the soybean checkoff.

Dear Friends,

Earlier this week, I received the biggest honor I've ever received. On Monday, March 21, I was recognized at the Points of Light Institute's "All Together Now" celebration in Washington, DC?an event honoring President George H. W. Bush for his visionary leadership in the American service movement, as well as other outstanding leaders who share his mission

I was highlighted in a five minute video for my service work. President Jimmy Carter narrated the video and introduced me after the video played. I was able to say a few brief words which earned me a standing ovation from the entire audience which included four former presidents -- William J. Clinton, Jimmy Carter, George H.W. Bush, George W. Bush and their families. Also in attendance was a star-studded lineup that included Brad Paisley, Garth Brooks, Reba McEntire, Kid Rock, Darius Rucker, and Carrie Underwood.

I believe this is the first time all four former presidents were together for an event since the inauguration of President Obama. This evening was a very positive and unique way to celebrate voluntary service.

I would have never had this opportunity and honor without your support.  I thank you very much for your continued support which is why LL&W is able to continue its mission to help clean America's rivers.

"All Together Now: A Celebration of Service" will air on Monday, March 28, 2011 at 7:00 p.m. (CST) on NBC. I'm not sure if I will make the cut, but it is a program worth watching.

Best Regards,

Chad Pregracke

by U.S. Senator Chuck Grassley

In the last half-century, U.S. farmers have answered the call to help feed, clothe and fuel a growing world population. In 1960, a U.S. farmer on average fed 25 people. Thanks to a blend of advances in mechanization, pest control, biotechnology, animal husbandry and veterinarian medicine - along with conscientious stewardship of soil, water and resource management -- each U.S. farmer today feeds more than 144 people.

Even as farmers respond to marketplace demands for affordable, abundant supplies of food, leaner cuts of meat and wholesome grains and produce, an ever widening disconnect exists between production and consumption. From grocery shoppers to public policy makers, fewer people share an appreciation for the supply chain that exists from the farm to fork, let alone from the farm to fuel pump.

That's right. The fuel pump. The farmers hitting the fields this spring are not only working to feed an expanding world population, they are helping to displace U.S. dependence on foreign petroleum. For decades, political instability in the Middle East has influenced U.S. public policy. Taxpayers support strategic military and foreign policy decisions to protect U.S. national, economic and energy security, stemming in part from our dependence on foreign petroleum.

The risks to U.S. economic growth also are growing, especially as developing heavyweights, such as China and India, increase their consumption of the world's finite fossil fuels.

The simple truth is that the United States must take bold steps to sever foreign petroleum's stranglehold on America's economy and security. From my leadership position in the U.S. Senate, I have long championed public policy that would increase energy efficiency and conservation; support domestic energy production; and, develop alternative and renewable energy sources, including wind, biomass, hydroelectric, solar, geothermal and biofuels.

Consumers in the United States - who anticipate $4 per gallon gasoline by the peak summer driving season - understand how important it is to diversify and expand access to reliable, affordable energy. The extra money spent at the pump, now averaging about $3.56 per gallon for gasoline (I paid $3.39/gallon in Cedar Falls this week), shrinks consumers' purchasing power. That's bad news in a U.S. economy driven by consumer spending. Higher fuel prices also drive up the costs for goods and services throughout the U.S. economy, making it harder for businesses to expand, increase wages and create new jobs.

Congress has supported public policy to encourage growth in homegrown biofuels, such as ethanol. A federal tax incentive, called Volumetric Ethanol Excise Tax Credit - or VEETC -- was created to get the domestic ethanol industry off the ground. It's paired with an import tariff to prevent foreign ethanol producers from taking advantage of the domestic tax break.

Critics of America's domestic biofuels industry, who spew anti-ethanol propaganda, are putting America's energy, economic and national security at risk. Not to mention thousands of U.S. jobs. When the biodiesel federal tax credit lapsed in 2009, nearly 23,0000 jobs were wiped out. The U.S. ethanol industry supports nearly five times as many jobs.

Congress also created the Renewable Fuels Standard to get more biofuels at the pump. In 2010, nearly 90 percent of all gasoline sold in the U.S. contained ethanol. And the 13 billion gallons of homegrown ethanol reduced oil imports by 445 million barrels of oil.

Despite the long-term good investments clean-burning ethanol brings to the American public, from reducing dependence on foreign oil; creating jobs; protecting national security interests; helping the environment; and, diversifying U.S. fuel supplies, critics are still bad-mouthing ethanol.

In recent years, Big Oil has teamed up with Big Food Manufacturers to spread bad publicity about ethanol. They'd like to make ethanol a scapegoat for bigger grocery bills and higher prices at the pump. It's rather incredulous to consider they are playing into the hands of the likes of Hugo Chavez and Moammar Kadafi.

America's farmers understand that corn-based ethanol is better than dirty fossil fuels any day of the week. Would the taxpaying public rather support energy policies that support American agriculture's efforts to increase U.S. energy independence, or would taxpayers rather support policies that maintain the stranglehold of foreign petroleum?

In the United States Senate, I will continue my crusade in Washington to champion homegrown biofuels. Corn-based ethanol is just the beginning to even more biofuels breakthroughs. Just consider the first generation of ethanol, made from corn, has made possible the development of biofuels from cellulosic materials such as switch grass, corn stover and wood waste.

Rolling back the clock on the amazing contributions American agriculture has made to U.S. energy independence, a cleaner environment and national security would be a tragic mistake.

Washington, DC - March 25, 2011 - Today, Congressman Bruce Braley (IA-01) released the following statement after White House spokesperson Jay Carney was asked about Rep. Braley's letter calling for an accounting of the Libyan conflict. According to USA Today, Carney replied to reporters, "there are contingency funds...for this kind of thing." Today Rep. Braley said:

"Yesterday I asked for accountability on the question of how much this conflict is costing us, and I have yet to see a clear response from the White House. The fact that funds for contingency military operations exist doesn't answer the question of how much we're spending, and will continue to spend, in Libya. I'm not the only one asking these questions - the American people are demanding answers too. And the President must give Congress and all taxpayers an accurate answer."

Yesterday, Rep. Braley sent a letter to President Obama asking for a full accounting of the Libyan conflict and the costs to taxpayers. Speaker Boehner sent a similar letter to the President. Rep. Braley has previously called for a full accounting of the human and financial costs of the wars in Iraq and Afghanistan.

A copy of Rep. Braley's letter is available here: http://go.usa.gov/2K2

MADISON, Wis.?Facebook could be valuable at helping identify people who may be depressed and perhaps on the verge of suicide, according to research by the University of Wisconsin School of Medicine and Public Health and School of Pharmacy.

However, the findings also stress that Facebook should not be used as a substitute for clinical screening and medical treatment for people who are depressed or suicidal.

The study is the first of its kind to determine a connection between social-networking sites and identification of mental-health issues.  The investigators analyzed the Facebook profiles of 200 college sophomores and juniors.

Results showed that 25 percent of the students displayed one or more references to depression symptoms.

These references included decreased interest or pleasure in activities, change in appetite, sleep problems, loss of energy, and feelings of guilt and worthlessness.  None of the students in this study expressed suicidal thoughts.

According to Dr. Megan Moreno, a pediatrician, assistant professor at the School of Medicine and Public Health and lead author of the study, many of these students received encouragement from their Facebook friends on the Facebook page, who asked how they could help resolve their problems.

"People are getting support from other Facebook users when they display these comments, so it may be used as a mini-support group for depression," she says.  "Given the frequency of depression symptoms displayed, it's possible that depression disclosures on Facebook may actually help to reduce the stigma around mental illness."

The findings also indicated that 2.5 percent of profiles displayed enough information to merit screening for depression.

Moreno adds that while Facebook should not be used to formally diagnose depression, it may be valuable in identifying students who are contemplating suicide and help them receive needed treatment.

"Recent media reports indicated planned suicides that were displayed on Facebook before being carried out," she said.  "This highlights the urgent need to understand how often depression is displayed on Facebook and what this may mean.  Early identification of depression may be easier now if you see repeated references on Facebook."

The findings come on the cusp of a clinical report released today by the American Academy of Pediatrics that recommends pediatricians and parents take a more active role in monitoring their children's use of social-networking sites and ask questions concerning displays of sexual innuendo, drug and alcohol use, bullying, depression and social anxiety.  The report also suggests pediatricians increase their knowledge of digital technology so they can properly diagnose issues involving risky behaviors shown on social-networking sites.
