Dr Ian Fairlie spoke at one of our Oldbury lectures in November
Most scientists in this field agree that there is danger even in small doses of radiation
The Guardian, Wednesday 20 January 2010
Dr Ian Fairlie is an independent consultant on radiation risks and a former scientific secretary to the government's Committee Examining Radiation Risks from Internal Emitters. He is writing a book, Radiation Risks Revisited, commissioned by an independent environmental trust.
You reported the view that radiation risks are exaggerated, but left out vital information on radiation protection (Radiation health threat overstated - Oxford professor, 11 January). The article relied upon and extensively cited a retired professor of particle physics, Wade Allison, who is neither a radiation biologist nor an epidemiologist, and is not in my view an expert in radiation risks. Indeed, the other three scientists quoted in the article pointedly refrained from supporting Allison. His sole contribution to the literature is a self-published book.
An article alongside (Nuclear theory: the current consensus) states that "a single dose below 100 millisieverts (mSv) is usually considered safe", and later gives Allison's claim that "there is a threshold of about 200 mSv, below which the body can repair all DNA damage caused and, therefore, which is safe". But there is no safe dose of radiation: no matter how low it is, a small risk remains
The linear no-threshold (LNT) theory is used by all the world's radiation authorities - the UN Scientific Committee on the Effects of Atomic Radiation, the International Commission on Radiological Protection, the
