Speaking on behalf of a committee of experts that met to discuss the impact of the Chernobyl disaster, Klaus Stadie, the deputy director of the Nuclear Energy Agency, said the health issue was not closed. He told a news conference that "a more thorough and comprehensive investigation is planned at a later stage when more data are available for analysis."
Asked to explain the qualification about "other health risks," John Snihs, a Swedish radiation official, said that "we are always exposed to natural radiation." Therefore, he went on, radiation levels from the disaster must be compared to ordinary radiation levels to make sense.
On the other hand, Stadie said, the Western countries had learned a good deal about radiation containment after the accident at the light-water power reactor at the Three Mile Island plant in the United States seven years ago. But that reactor was similar to most other Western reactors.
