(Jerry Cuttler, Health Physics Society) Canada - Urgent Change Needed to Radiation Protection Policy13.Aug.2016
Jerry Cuttler: Although almost 120 years of medical experience and data exist on human exposure to ionizing radiation, advisory bodies and regulators claim there are still significant uncertainties about radiation health risks that require extreme precautions be taken. In the `950s, without scientific evidence, the Natitonal Academy of Sciences Biological Effects of Atomic Radiation (BEAR) Committee recommended that the linear no-threshold (LNT) model be used to assess the risk of radiation-induced mutations in germ cells and the risk of cancer in somatic cells.

Background radiation across the Earth varies from 3 mrem/yr (0.03 mSv/yr) over the oceans to 10,000 mrem/yr (100 mSv/yr) in areas of high elevation made up of granitic rocks. Thus, it is not surprising that populations subjected to radiation levels of 10,000 mrem (100 mSv) or below, either natural or man-made, show radiation effects that are not statistically different from zero.

World Council on Isotopes, website: http://www.wci-ici.org/ has many interesting articles and conferences on isotopes, radioisotopes, and radiation. In this issue for April, 2016 focus is on Article (1) Radiation Applications: Looking to the Future by Alan Waltar and Article (2) Introduction to the ‘Act on the Promotion and Management of Non-Destructive Testing Technology’ of Rep. Korea by Tae Soon Son.

We need more than ever to have a reasoned discussion on the issues. It is important also to see these disasters in the wider context of energy production: when the Banqiao hydroelectric dam failed in China in 1975 it led to at least 171000 deaths and displaced 11 million people. Our reliance on fossil fuels is particularly costly, not only to the environment but to human health; each year, at least 1.3 million people are estimated to die from air pollution. Shutdown of the plants in Japan has led to not only increased pollution, but rolling blackouts and protests. By contrast, France has for decades produced 75% of its energy through nuclear, and enjoys the cleanest air and among the lowest carbon emissions of any industrialised nature.
