Living In Nuclear Disaster Fallout Zone Would Be No Worse Than Living In London, Research Suggests

An anonymous reader quotes a report from University of Bristol, England: New research suggests that few people, if any, should be asked to leave their homes after a big nuclear accident, which is what happened in March 2011 following the Fukushima Daiichi nuclear disaster. Professor Thomas’s team used the Judgement or J-value to balance the cost of a safety measure against the increase in life expectancy it achieves. The J-value is a new method pioneered by Professor Thomas that assesses how much should be spent to protect human life and the environment. The researchers found that it was difficult to justify relocating anyone from Fukushima Daiichi, where four and a half years after the accident around 85,000 of the 111,000 people who were moved out by the Japanese government had still not returned. After the world’s worst nuclear accident at Chernobyl in 1986, in what was then part of the Ukrainian Soviet Socialist Republic of the Soviet Union (USSR), the J-value method supported relocation when nine months’ or more life expectancy would be lost due to radiation exposure by remaining. Using the J-value method, 31,000 people would have needed to be moved, with the number rising to 72,000 if the whole community was evacuated when five per cent of its residents were calculated to lose nine months of life or more.

Philip Thomas, Professor of Risk Management in the Department of Civil Engineering at the University of Bristol, said: “Mass relocation is expensive and disruptive. But it is in danger of becoming established as the prime policy choice after a big nuclear accident. It should not be. Remediation should be the watchword for the decision maker, not relocation.” For comparison, the average Londoner loses four and a half months to air pollution, while the average resident of Manchester lives 3.3 years less than his/her counterpart in Harrow, North London. Meanwhile, boys born in Blackpool lose 8.6 years of life on average compared with those born in London’s borough of Kensington and Chelsea. The results are published in a special issue of Process Safety and Environmental Protection, a journal from the Institution of Chemical Engineers.
