GEOLOGY AND 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...

Use of unabsorbed radioactive marker substances in a re-assessment of the radioactive triolein test of fat absorption.

The radioactive triolein test has been compared with two chemical methods for the assessment of fat absorption in a group of inpatients from general medical wards. The special feature of the investigation is the use of a radioactive faecal marker to measure the completeness of faecal collections during the investigation period. Estimations of unabsorbed (131)I triolein and faecal fat measured b...
