Working Environment Measurement of Radioactive Substances

Carcinogenesis by radioactive substances.

Knowledge of the potential dangers of exposure to radioactive substances and the insti tution of proper safety precautions have helped to reduce accidental exposures to radioactive substances. However, the carcinogenic hazard from them has by no means been eliminated, and, in spite of the exercise of reasonable care and the use of improved technics, accidents in the laboratory and indust ry may...

Safe handling of tissue containing radioactive substances.

Patients recently treated with radioactive isotopes may present problems or even hazards during physical examination, operation or autopsy, especially following the use of iodine isotopes and 198Au. 32P is rarely a significant hazard. Contamination of victims of radiation accidents may be a problem initially, but they are usually promptly decontaminated. Guidance of the hospital's radiation saf...

The Toxicology of Radioactive Substances. Volume 2

as the record of a meeting or symposium. These books vary from the valuable to the useless. Whatever intrinsic merit they may have is too often vitiated by the long delays in publication. If editors insisted on manuscripts at the time of the oral presentation, many of these publications could be expeditiously placed in the hands of the reader while still relatively timely. In evaluating this CI...

Radioactive Aerosols in the Environment

Radioactive aerosols differ physically from non-radioactive aerosols by the appreciable charge that they may carry. This arises from a competition between the charge generated by the radioactive decays occurring within each aerosol and the subsequent diffusion of the ions formed back onto the particle. At high levels of activity, the particles may self-discharge, at low and intermediate activit...
