[en] This handbook was conceived in order to fill the need of health physics practitioners, technicians, and students for an easy to use, practical handbook containing health physics and radiological health data. While briefer and more specific data sources are sources are available on single subject areas, as are multi-volume compendia, there is no current up-to-date compilation of information useful on a daily basis by the health physicist. Separate abstracts have been prepared for 16 chapters in this book

[en] Estimates, based on an empirical model and computer program (Ellis, Healy, Shleien and Tucker, HEW publication (FDA)76-8015), have been calculated and are presented on the mean active bone marrow dose to adults from diagnostic radiography, fluoroscopy, and dental radiography as practiced in the United States in 1970. The annual per capita mean active bone marrow dose in 1970 to adults from the above practices is estimated to have been 103 mrad; 77 percent, 20 percent, and 3 percent from radiographic, fluoroscopic and dental examinations, respectively. Examinations of the upper and lower abdomen contribute approximately 39 percent each to the total mean active bone marrow dose for adults; those of the pelvis, 4 percent; the thorax, 12 percent; and head and neck examinations (including dental) contribute about 6 percent. The per capita mean active bone marrow dose for various age groups is discussed. Contributions to the dose within a given age group from different examinations indicate that in the 15 to 34 year age group lumbar and lumbosacral spine examinations contribute most to the mean active bone marrow dose. Thereafter upper Gi series and barium enemas are the highest contributors. Mean active bone marrow doses for children are not estimated in this presentation due to insufficient data. However, the lower rate of use of diagnostic x rays (except dental) in children would reduce the annual per capita mean active bone marrow dose for the entire population to approximately a maximum of 77 mrads. The results may be viewed relative to several surveys of radiation doses from diagnostic radiology performed in other countries which reported annual per capita mean active bone marrow doses varying from 30 to 189 mrads for their entire populations, and with natural background for which the annual per capita whole body and bone marrow dose in the United States is approximately 130 and 86 mrads, respectively

[en] This report provides background material for the development of FDA's Protective Action Recommendations: Accidental Radioactive Contamination of Food and Animal Feeds. The rationale, dosimetric and agricultural transport models for the Protective Action Guides are presented, along with information on dietary intake. In addition, the document contains a discussion of field methods of analysis of radionuclides deposited on the ground or contained in milk and herbage. Various protective actions are described and evaluated, and a cost-effectiveness analysis for the recommendations performed

[en] This is a book review of The Health Physics and Radiological Health Handbook. The author discusses the highlights of this near-encyclopedic compendium on Health Physics. He stresses that in spite of an abundance of typographical errors, that it is a very good and complete reference tool

[en] The exposure measurements, model and computer program for estimation of mean active bone marrow doses formerly employed in the 1962 British Survey of x-ray doses and proposed for application to x-ray exposure information obtained in the U.S. Public Health Service's X-Ray Exposure Studies (1966 and 1973) are described and evaluated. The method described is feasible for use to determine the mean active bone marrow doses to adults for examinations having a skin to source distance of 80 cm or less. For a greater SSD, as for example in chest x rays, a small correction in the calculation dose can be made
