Busting the myths against nuclear power

The word Chernobyl became synonymous with death on a massive scale. But perception and reality do not always neatly align; in the wake of the disaster, the UN Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) and others undertook a co-ordinated effort to follow up on health effects. In 2006, after two decades of monitoring they outlined the health effects; of the firefighters exposed to the huge core doses and incredibly toxic smoke, 28 died from acute radiation sickness. A further 15 perished from thyroid cancer. Despite aggressive monitoring for three decades, there has been no significant increase in solid tumours or delayed health effects, even in the hundreds of thousands of minimally protected cleanup workers who helped purge the site after the accident. In the words of the 2008 UNSCEAR report: “There is no scientific evidence of increases in overall cancer incidence or mortality rates or in rates of non-malignant disorders that could be related to radiation exposure."

It added: “The incidence of leukaemia in the general population, one of the main concerns owing to the shorter time expected between exposure and its occurrence compared with solid cancers, does not appear to be elevated. Although most highly exposed individuals are at an increased risk of radiation-associated effects, the great majority of the population is not likely to experience serious health consequences as a result of radiation from the Chernobyl accident. Many other health problems have been noted in the populations that are not related to radiation exposure.”

Despite the preponderance of breathless headlines since the reality is that five years later, radiobiological consequences of Fukushima are practically negligible - no one has died from the event, and is it extraordinarily unlikely that anyone will do so in future. The volume of radioactive leak from the site is so small as to be of no health concern; there is no detectable radiation from the accident in Fukushima grown-food, nor in fish caught off the coast.
