The secretive Soviet handling of information about the Chernobyl reactor accident regrettably prevents the scientific world from participating in what would have been an important learning experience concerning reactor safety and radiation biology.
The failure of the Soviets to have provided details about the design of the reactor, the nature of the containment vessel, if any, the cause of the violent explosion, and the precipitating episode makes it difficult to determine whether the accident holds any lessons for American reactors.
However, of even greater concern to me is that this very unfortunate accident could have permitted an enormous increase in our knowledge in the field of radiation biology: the immediate and long-term consequences associated with exposure to radiation at different doses and dose rates.
Much of what we have learned about late radiation effects in humans has come from the Hiroshima-Nagasaki experience. Even now, 40 years afterward, attempts are being made to recalculate the acute radiation doses received by the 82,000 survivors. Certainly, retrospective analysis could never provide the accurate dosimetry that would now be possible if one could study the population in the environs of the Chernobyl reactor.
Based on the studies of the Atomic Bomb Casualty Commission (ABCC) and its successor, the Radiation Effects Research Foundation (RERF), it has been estimated that, added to the 4,500 cancer deaths normally expected through 1978 among the Japanese survivors had they not received radiation from the bomb, there were
