1954 "National Committee on Radiation Protection and Measurements" Page 23: "Permissible dose may then be defined as the dose of ionizing radiation that, in the light of present knowledge, is not expected to cause appreciable bodily injury to a person at any time during his lifetime. As used here, 'appreciable bodily injury' means any bodily injury or effect that the average person would regard as being objectionable and/or competent medical authorities would regard as being deleterious to the health and well-being of the individual."
1961: "National Committee on Radiation Protection and Measurement" Page 3: "There can be no single permissible or acceptable level of exposure without regard to the reasons for permitting the exposure. It is basic that exposure to radiation should result from a real determination of its necessity. There can be different Radiation Protection Guides with different numerical values, depending upon the circumstances. The guides recommended herein are appropriate for normal peacetime operations."
2013 The Obama Administration accepted a cancer rate of at least 1 person per 135 residents* after a nuclear accident, for people living in contaminated areas deemed "safe". This cancer rate is based on:

may be situations where a sustainable agricultural economy isn't possible
without placing contaminated food on the market. As such foods will
be subject to market forces, this will necessitate an effective communication

1965: "Background material for the development of radiation protection standards" Pages 5 to 6: "Caution should be exercised in decisions to take protective actions in situations where projected doses are near the numerical values of the Radiation Protection Guides (RPG), since the biological risks are so low that the actions could have a net adverse rather than beneficial effect on the public well-being."
