Excerpt: The Chernobyl disaster triggered the release of substantial amounts of radiation into the atmosphere in the form of both particulate and gaseous radioisotopes. It is the most significant unintentional release of radiation into the environment to date. It has been suggested that the radioactive contamination caused by the Chernobyl disaster greatly exceeded that of the atomic bombing of Hiroshima and Nagasaki in 1945. However, the work of the Scientific Committee on Problems of the Environment (SCOPE) suggests that the two events cannot be directly compared, with a number suggesting that one was x times larger than the other; the isotopes released at Chernobyl tended to be longer-lived than those released by a bomb detonation, producing radioactivity curves that vary in shape as well as size. The inhalation dose (internal dose) for the public (during the time between the accident occurring and their evacuation from the area) in what is now the 30 km evacuation zone around the plant has been estimated (based on ground deposition of caesium-137) to be between 3 and 150 mSv for adults (depending on the distance from the reactor and the day of evacuation) and for one year old children a dose estimate of between 10 and 700 mSv has been made. Thyroid doses for adults were between 20 and 1000 mSv, while for the one year old infants these were higher at 20 to 6000 mSv. For those who left at an early stage in the accident the internal dose due to inhalation was 8 to 13 times higher than the external dose due to gamma / beta emitters. For those who remained until later (day 10 or later) the ...
