Radiation Exposure and Risk

Ionizing radiation damages living things and contaminates the environment, sometimes permanently. Studies have shown increases in cancer around nuclear facilities and uranium mines. Radiation mutates genes which can cause genetic damage across generations.

Erin Brockovich warns about radioactive "Hot Water" released by U.S. atomic reactors

Erin Brockovich, shown here, was portrayed by Julia Roberts in a box office hitCNN interviewed famous environmentalist Erin Brockovich (pictured, left) about her new novel, Hot Water, on the health risks of radioactivity leaks into the environment from nuclear power plants across the U.S. Brockovich warns that radioactivity ingestion by children, as evidenced through such projects as the "Tooth Fairy," could begin to explain cancer epidemics in certain locales nationwide. Beyond Nuclear has long warned that it is not just accidental ("unmonitored, uncontrolled") leaks of hazardous radioactivity, but also "routine releases" (supposedly "controlled and monitored") allowed and permitted by government regulators as a daily part of atomic reactors' operations, that need to be stopped. Children are significantly more vulnerable to radiation's hazards, as revealed by the Institute for Energy and Environmental Research's "Healthy from the Start" campaign.

25-40% underestimates of radiation doses to 1,769 Canadian health care workers undetected for 4 years

The Star has reported that 1,769 Canadian health care workers suffered radiation doses 25 to 40% worse than they were told four years ago, due to an error in a computer program administered by Health Canada. The Canadian Nuclear Safety Commission regulates Health Canada on such matters, but both federal agencies missed the error for 4 years. Some health care workers were exposed to above permissible doses, once the error was caught. CNSC also regulates Canadian atomic reactors, and other nuclear facilities and activities. The article closed by quoting Mark Mattson of Lake Ontario Waterkeeper:

"Mark Mattson of Lake Ontario Waterkeeper, who has opposed construction of new nuclear units at Darlington, said the incident raises question about the nuclear regulator – which also oversees nuclear power stations.

'The shocking thing here is that no one noticed the mistake for four years,' he said.

'Waterkeeper is very interested to see who is held accountable for this mistake. In recent years, we have become increasingly concerned that the CNSC is lax when it comes to enforcing the rules.' "

Not on Our Fault Line calls on NRC to distribute KI within 20 miles of North Anna

U.S. Rep. Ed Markey (D-MA)Not on Our Fault Line, a group of concerned citizens which formed in response to the 5.8 magnitude earthquake of August 23, 2011 epicentered just 11 miles from the North Anna nuclear power plant, is calling on the U.S. Nuclear Regulatory Commission to enforce a 2002 law requiring the distribution of potassium iodide (KI) tablets within 20 miles of U.S. atomic reactors. KI saturates the human thyroid gland, blocking uptake of hazardous Iodine-131, a viciously radioactive substance that escaped during the Chernobyl nuclear catastrophe, causing an epidemic of thyroid disease downwind in Ukraine, Belarus, and Russia. Large quantities of I-131 also escaped during the Fukushima triple reactor core meltdown and radioactive waste storage pool fire that began in March 2011, leading the Japanese federal government to warn parents not to use Tokyo's tap water for infants during the early days of the catastrophe due to I-131 contamination. I-131 has an 8 day half life; thus, its hazardous persistence lasts 80 to 160 days.

Section 127 of the Bioterrorism Preparedness and Response Act of 2002 was sponsored as a successful amendment by U.S. Representative Ed Markey (D-MA, pictured above left), a long time watchdog on the nuclear power industry. In May, 2011, Markey led a bipartisan letter of House Members addressed to President Obama, calling for implementation of the law. 9 long years after its enactment, NRC still had not enforced the law. Markey issued a press release about the letter to Obama, signed by 30 Members of Congress. As the congressional letter to the president states, "Children are the most vulnerable because their thyroid glands concentrate more iodine on a mass basis than adults and are more sensitive to radiation because of their rapidly growing cells."

Cesium found in Japan baby formula

Traces of radiation spilled from Japan’s hobbled nuclear plant were detected December 6 in baby formula manufactured by Meiji Co, a major food and candy maker. The formula had been manufactured in March. The company has recalled the formula although the Japanese authorities insist there is no risk to babies' health. This despite the scientifically-held position that there is "no safe dose" of radiation and studies that show prolonged exposure to low levels of radiation can be harmful.

Hazardous radiation dusts all of Japan

"Radioactive substances from the crippled Fukushima No. 1 nuclear power plant have now been confirmed in all prefectures [in Japan], including Uruma, Okinawa Prefecture, about 1,700 kilometers from the plant, according to the science ministry," reports the Japan daily, the Asahi Shimbun. "The highest combined cumulative density of radioactive cesium-134 and cesium-137 was found in Hitachinaka, Ibaraki Prefecture, at 40,801 becquerels per square meter. That was followed by 22,570 becquerels per square meter in Yamagata, the capital of Yamagata Prefecture, and 17,354 becquerels per square meter in Tokyo's Shinjuku Ward."
