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.

UN special report on Fukushima criticizes handling of radiation catastrophe, suggests positive steps forward

Anand Grover, the United Nations Special Rapporteur reports on Fukushima, some highlights:

-potassium iodine was not handled properly.

-government did not evacuate properly or communicate radiation doses and implications to the public.

-government neglected hotspots and used 20msv/year limit implying this was safe which is not.

-radiation monitoring stations did not adequately reflect exposure data. Therefore all validated data, alot being collected by private individuals, should be made public.

-provide holistic and comprehensive treatment for ALL radiation effected zones and include wider health consequences than the current health survey.

-err on side of caution and monitor health outcomes for an extensive period of time.

-allow individuals access to their health data and that of their children.

-initiate long-term monitoring of sub-contract workers at the ruined plants.

-evacuation centers did not provide adequate facilities for women with children and the disabled and elderly. Separation of families due to inadequate evacuation procedures has caused unnecessary anguish.

-government needs to strengthened food contamination monitoring.

-adopt an action plan with clear timeline to reduce contamination to 1msv per year.

-restore subsidies to all evacuees so they can make proper decisions about whether to return or leave.

-government ensure that TEPCO is held financially accountable and that taxpayers are not.

-ensure participation of effected people, particularly vulnerable groups during all parts of decision-making process, including health services and decontamination. This is not currently being done.

-implement the “act on protection and support for children, and other victims of the Tepco disaster” which was enacted in June, 2012. This act provides a framework for those affected by the disaster and provides opportunity to enlist affected people in decision-making. video

Even Low-Level Radioactivity Is Damaging, Scientists Conclude

Even the very lowest levels of radiation are harmful to life, scientists have concluded in the Cambridge Philosophical Society's journal Biological Reviews...

The review is a meta-analysis of studies of locations around the globe that have very high natural background radiation as a result of the minerals in the ground there...

The scientists reported significant negative effects in a range of categories, including immunology, physiology, mutation and disease occurrence. The frequency of negative effects was beyond that of random chance.

"There's been a sentiment in the community that because we don't see obvious effects in some of these places, or that what we see tends to be small and localized, that maybe there aren't any negative effects from low levels of radiation," said Mousseau. "But when you do the meta-analysis, you do see significant negative effects."

"It also provides evidence that there is no threshold below which there are no effects of radiation," he added...

"With the levels of contamination that we have seen as a result of nuclear power plants, especially in the past, and even as a result of Chernobyl and Fukushima and related accidents, there's an attempt in the industry to downplay the doses that the populations are getting, because maybe it's only one or two times beyond what is thought to be the natural background level," he said. "But they're assuming the natural background levels are fine."

"And the truth is, if we see effects at these low levels, then we have to be thinking differently about how we develop regulations for exposures, and especially intentional exposures to populations, like the emissions from nuclear power plants, medical procedures, and even some x-ray machines at airports."

Fracking and Radium, the Silvery-White Monster 

Fracking for gas not only uses toxic chemicals that can contaminate drinking water and groundwater -- it also releases substantial quantities of radioactive poison from the ground that will remain hot and deadly for thousands of years. Huffpost

Fukushima trout log radioactivity level over 100 times gov't limit

A mountain trout caught in a Fukushima Prefecture river returned a radioactive cesium reading of 11,400 becquerels per kilogram, more than 100 times the government-set limit for food items, a survey by the Environment Ministry said Friday. Kyodo News

Radioactivity is persisting in the ocean waters close to Japan's ruined nuclear power plant at Fukushima Daiichi

Radioactivity is persisting in the ocean waters close to Japan's ruined nuclear power plant at Fukushima Daiichi. New data presented at a conference held on 12–13 November at the University of Tokyo show that levels of radioactivity in the sea around the plant remain stable, rather than falling as expected. Researchers believe that run-off from rivers, as well as continued leaks from the plant, may be partially to blame. But contaminated sediment and marine organisms also seem to be involved...

...The Fukushima disaster caused by far the largest discharge of radioactivity into the ocean ever seen. A new model presented by scientists from Woods Hole Oceanographic Institution in Massachusetts estimates that 16.2 petabecquerels (1015 becquerels) of radioactive caesium leaked from the plant — roughly the same amount that went into the atmosphere.
