Radiation and Cancer

Enenews is running a post on a very important study that has found a clear correlation between exposure to low levels of ionizing radiation and subsequent cancer. Below find a link to the Enenews post and to the study's citation (plus a brief excerpt).

This study is very important in light of the fact that Japan has stated that 20 millisieverts a year of radiation exposure is perfectly safe, even for children. The study found every 10 millisieverts of radiation increased cancer risk in a 5 year period by 3%.

Additionally, one of the Enenews community members (an epidemiologist) has been keeping epidemiological statistics on excess deaths in the US that may be attributed to Fukushima

Cancer risk related to low-dose ionizing radiation from cardiac imaging in patients after acute myocardial infarction. By Mark J. Eisenberg MD MPH, Jonathan Afilalo MD MSc, Patrick R. Lawler MD, Michal Abrahamowicz PhD, Hugues Richard MSc, Louise Pilote MD MPH PhD

The cumulative exposure to radiation from cardiac procedures was 5.3 milli Sieverts (mSv) per patient year, of which 84% occurred during the first year after acute myocardial infarction. A total of 12 020 incident cancers were diagnosed during the follow-up period. There was a dose dependent relation between exposure to radiation from cardiac procedures and subsequent risk of cancer. For every 10 mSv of low-dose ionizing radiation, there was a 3% increase in the risk of age- and sex-adjusted cancer over a mean follow-up period of five years (hazard ratio 1.003 per milliSievert, 95% confidence interval 1.002–1.004).


Readers unfamiliar with Deadly Deceit: Low-level Radiation, High-level Cover-up by Dr. Jay M. Gould (Author), Benjamin A. Goldman should look also at this study because it found after Chernobyl that for human infants the dose-response is “supralinear” rather than linear, “which means that infant mortality rises more rapidly at low doses.” 
In June of 2011, the online journal Counterpunch published an article by Dr. Janet Sherman and epidemiologist Joseph Mangano reporting a 35 percent spike in infant mortality rates for the 10 weeks following Fukushima’s March releases in 8 US cities (Boise ID, Seattle WA, Portland OR, plus the northern California cities of Santa Cruz, Sacramento, San Francisco, San Jose, and Berkeley). 

The report, using CDC data, was challenged for allegedly cherry picking data to support conclusions. Counterpunch subsequently had their statistical consultant, Pierre Sprey, evaluate and confirm the analysis. Sprey found the analysis to be robust.
