UN Scientific Committee on Effects of Atomic Radiation, Fukushima Report
Sara.TillThe report encompasses reports on the proceedings of the UN Scientific Comittee during its 60th session, May 2013. The UN report presents an unbiased plethora of data surmising Fukushima radiation exposure to both human an biological life. It primarily focuses on 2 reports detailing aspects of radiation exposure during the 2011 nuclear accident. The first report gives estimated levels of radiation experienced by individuals and non-human biota. Human individuals estimates are based on age and ongoing proximity to the accident. Evacuated adult citizens had an estimated exposure <10 mSv, while workers experienced doses >10mSv, with the highest exposure an estimated 100 mSv. It places these values within the context of lifelong anticipated exposure and international expected exposures. This first report also briefly discusses effects beyond radiation, including the adverse outcomes thousands faced by evacuating. The second report concentrates on radiation exposure of children during the accident. While it concludes longer epidemological studies are needed to accurately assess the prevailing biolgogical effects, several important facts are highlighted. At a given radiation dose, children are more at risk of tumor induction than adults. In addition to this increased radiosensitivity (partially due to physical factors such as size), children also demonstrate increased prevalence of several cancers. These include leaukemia, brain, and thyroid cancers, all of which show radiosensitivity. The report also suggests narrowing the scope of inquiry, as radiation-induced cancers can be influenced by factors such as age and gender.
