Available in PDF, EPUB and Kindle. Book excerpt: This study was designed to measure the life shortening of C57BL/6J male mice as a result of exposure to five external doses from 6°Co gamma radiation delivered at six different dose rates. Total doses ranged from 20 to 1620 rad at exposure rates ranging from 0.7 to 36,000 R/day. The ages of the mice at exposure were newborn, 2, 6, or 15 months. Two replications were completed. Although death was the primary endpoint, we did perform gross necropsies. The life span findings are variable, but we found no consistent shortening compared to control life spans. Therefore, we cannot logically extrapolate life shortening to lower doses, from the data we have obtained. In general, the younger the animals were at the beginning of exposure, the longer their life spans were compared to those of controls. This relationship weakened at the higher doses and dose rates, as mice in these categories tended not to have significantly different life spans from controls. Using life span as a criterion, we find this study suggests that some threshold dosage may exist beyond which effects of external irradiation may be manifested. Up to this threshold, there is no shortening effect on life span compared to that of control mice. Our results are in general agreement with the results of other researchers investigating human and other animal life span effects on irradiation.

Book excerpt: Radiation Hormesis presents the only critical review of the effects of whole-body exposure to low doses of ionizing radiation in animals. This is a "must read" book for radiobiologists, health-conscious individuals, and serious environmentalists. Topics discussed include our radiation environment, radiation hormesis in cancer mortality, growth and development, reproduction and mutation, immunity, and cancer. Data is presented that indicates that low doses of ionizing radiation may actually be beneficial to human health. This information could invalidate the "zero thesis" and linear models used by most regulatory agencies. The implications regarding eliminating linear models and accepting radiation hormesis are also discussed.

Book excerpt: Data are presented on the life span of nine inbred strains and five hybrid strains of mice based on 400 mice of each sex for inbred and 200 mice of each sex for hybrid. Some of these mice were exposed when 120 days old to 250 R or 450 R of x radiation delivered at a dose rate of 60 R/min. Data on strain, sample size, and mean survival times are presented in tables.

This book was released on 2000 with total page 592 pages. Available in PDF, EPUB and Kindle. Book excerpt: The growing knowledge about the mechanisms of carcinogenesis and the critical analysis of the assumption on which the no-threshold linear relation is based have advanced, but dose-effect relations must be found which optimize the overall epidemiological and experimental data. It is abundantly clear that the standards that will be enforced upon the entry into the force of the International directive no longer enjoy the scientific justifications which made them credible, and that concepts like collective dose and the ALARA (As Low As reasonably Achievable) principle are obsolete. Yet this merely raises, with even greater sharpness, the key question: what can replace them? In this respect, research on the influence of variations in natural irradiation on cancer frequently represent a vital source of information. Radiological protection has entered what some call a turbulence zone, others a renewal. The dogmas on which it lived for more than two decades have been questioned, giving the medical and scientific community a dual responsibility.
