"In Permissible Dose, J. Samuel Walker examines the evolution over more than a hundred years of radiation protection standards and efforts to ensure radiation safety for nuclear workers and for the general public. Clearly the risk of exposure to radiation, even in small doses, has aroused more sustained controversy and public fear than any other comparable industrial or environmental hazard, but this was not always so.

The discovery of x-rays and natural radioactivity in the 1890s was greeted with enthusiasm, which turned to apprehension as evidence about the dangers of radiation gradually accumulated. What was known, and when, and what was done about it, is a major twentieth-century story reflecting a complex interaction of scientific and political issues.".

"By clarifying the nature of the radiation debate, Walker puts in perspective the public's intense fear of radiation, whether in response to fallout from nuclear bomb testing, exposure from medical or manufacturing procedures, effluents from nuclear power or radioactivity from other sources.

Permissible dose levels are a key to the principles and practices that have developed in the field of radiation protection since the 1930s, and to their highly charged political and scientific history as well."--BOOK JACKET.
