Hiroshima Porcelain Pieces Provide Insight Into Exposure Levels

Summary:
Scientists are still studying the after-effects of the nuclear disaster caused by an atomic bomb dropped on Hiroshima on August 6, 1945. The amount of neutron fluence, for example, has been calculated from the site to establish what might be a safe level of exposure for humans. (Neutron fluence is the number of neutrons from the blast found per square centimeter.) The advent of nuclear accidents such as Three Mile Island and potential nuclear accidents in the future makes accurate information imperative. But scientists have recently realized that there are discrepancies in earlier estimates and have been looking for ways to resolve them. According to the latest research, the standards for a safe level of exposure to humans might be too conservative.
