I’m an independent consultant on radioactivity in the environment living in London UK. I’ve studied radiation and radioactivity at least since the Chernobyl accident in 1986. I’ve a degree in radiation biology from Bart’s Hospital in London and my doctoral studies at Imperial College in London and (briefly) Princeton University in the US concerned the radiological hazards of nuclear fuel reprocessing. I formerly worked as a civil servant on the regulation of radiation risks from nuclear power stations. From 2000 to 2004, I was head of the Secretariat of the UK Government’s CERRIE Committee on internal radiation risks. Since retiring from Government service, I have been a consultant on radiation matters to the European Parliament, local and regional governments, environmental NGOs, and private individuals. My areas of interest are the radiation doses and risks arising from the radioactive releases at nuclear facilities.
