内容説明

This book looks at the risks to man from exposure to low doses of radiation at low dose rates, a matter for intense scientific debate. The effects of low doses are not directly measurable in man and thus risks must be inferred from studies on populations exposed to high doses. It is this inference that is contentious. The book commences with papers by figures in the field of radiation epidemiology, reviewing the current status of studies on human populations exposed to radiation, including the survivors of the atomic bombings in Japan. The remaining papers, by researchers in the field of radiobiology, have been written in response to an invitation to address 12 questions fundamental to the interpretation of these data in terms of the effects of low doses. They represent the current status of radiobiology and its ability to address the problem.

目次

  • Part 1 Review of current status of Japanese A-bomb study: the new radiation dosimetry for the A-bombs in Hiroshima and Nagasaki
  • the new dose system and radiation induced cancer risks among A-bomb survivors
  • radiation-related damage to the developing human brain
  • the genetic effects of the atomic bombs - problems in extrapolating from somatic cell findings to risk for children
  • cancer risk estimation from the A-bomb survivors - extrapolation to low doses, use of relative risk models, and other uncertainties. Part 2 Review of epidemiological studies: epidemiological studies of children irradiated in utero
  • epidemiologic studies on uranium miners and other groups exposed to radon
