DOWNLOAD EBOOKThe US Environmental Protection Agency Office of Radiation and Indoor Air asked the National Research Council to evaluate whether sufficient new data exist to warrant a reassessment of health risks reported in Health Effects of Exposure to Low Levels of Ionizing Radiations (BEIR V) in 1990. To respond to this request, the National Research Council assembled the Committee on Health Risks of Exposure to Low Levels of Ionizing Radiations. The work of the committee was conducted in what was called the BEIR VII phase-1 study. To assist the committee during its deliberations, various scientists were consulted for advice, and a workshop on the impact of biology on risk assessment was held in collaboration with the Department of Energy Office of Health and Environmental Research. The intent of the workshop was to address the implications of new understanding of the biologic basis of radiation injury and carcinogenesis for risk assessment.

DOWNLOAD EBOOKFacilities are established at the Armed Forces Radiobiology Research Institute (AFRRI) to perform radiation-induced chromosome aberration analysis for biological dosimetry. Whole blood from healthy human volunteers was used after obtaining informed consent. Peripheral blood lymphocytes were exposed in vitro to different types of radiation; sup 60 Co gamma rays (E(gamma) = 1.25 MeV, mean of the absorbed dose distribution of the lineal energy, y(sub D) = 1.9 keV/micrometers, 1 Gy/min); x rays (250 kV(sub p), E = 83 keV, y(sub D) = 4 keV/micrometers, 1 Gy/min); or a fission-spectrum neutron source (E = 0.71 MeV, y(sub D) = 65 keV/micrometers, 0.25 Gy/min). Distribution of radiation-induced dicentrics among cells exhibited Poisson statistics as characterized by the Papworth method (Papworth 1970). Dose-response relationships for the yield of dicentrics for photon sources were fitted with a linear-quadratic model using the maximum-likelihood method and for the neutron source by a weighted linear regression method. Comparison of the data with other published studies is presented. The dose-response relationships for dicentric induction by low-and high-linear energy transfer (LET) radiation are consistent with the single- and two-track model of aberration formation, Y = alpha D + beta D(sup 2). An increase in y(sub D) resulted in an increase in dicentric yield. As expected, fission neutrons induced a significantly higher yield of dicentrics than that caused by low-LET sources. The linear component of the model, corresponding to damage caused by single-tracks, is predominant with fission neutrons so that the dose-effect relationship is essentially linear. An automated metaphase finder system with a satellite scoring utility was used to improve data collection.

DOWNLOAD EBOOKBEIR VII develops the most up-to-date and comprehensive risk estimates for cancer and other health effects from exposure to low-level ionizing radiation. It is among the first reports of its kind to include detailed estimates for cancer incidence in addition to cancer mortality. In general, BEIR VII supports previously reported risk estimates for cancer and leukemia, but the availability of new and more extensive data have strengthened confidence in these estimates. A comprehensive review of available biological and biophysical data supports a "linear-no-threshold" (LNT) risk modelâ€"that the risk of cancer proceeds in a linear fashion at lower doses without a threshold and that the smallest dose has the potential to cause a small increase in risk to humans. The report is from the Board on Radiation Research Effects that is now part of the newly formed Nuclear and Radiation Studies Board.

DOWNLOAD EBOOKHuman health as well as aquatic and terrestrial ecosystems are threatened from increa sing levels of environmental radiation of various sources, many of them of anthropoge nic causality: large areas of the former Soviet Union suffer from radioactive pollution, in particular after the Chemobyl accident; the increase in the incidence of UVB radiati on at the Earth's surface as a result of a progressive depletion of stratospheric ozone is a global problem that requires international concerted actions; in areas of former uranium mining the natural radiation level is substantially increased due to elevated radon levels; a growing portion of the population involved in air traffic is exposed to increased levels of natural radiation; and with the International Space Station an increasing number of astronauts will be exposed to the complex field of cosmic radiation. To estimate the corresponding risks, a better knowledge of the underlying radiobiological mechanisms at the molecular, cellular and system level is required. This book is the result of a multidisciplinary effort to discuss the current state of knowledge of the fundamental processes that result from interactions of environmental radiation -ionizing as well as UV radiation -with living matter and the existing radiati on protection concepts, and then to define future research work needed as fundamental information for the assessment of risks from increased levels of environmental radiation to human health and ecosystem balance. It comprises the key lectures and statements presented at the NATO Advanced Research Workshop.
