Environmental radioactivity
Tóm tắt
Studies of radioactive contamination of various media in the biosphere carried out at the Radium Institute over many years have made it possible to develop methods of investigation which are widely applicable at the present time. A large amount of data has been accumulated on the distribution of radioactive contaminants in space and on the variation of their concentration in time. Certain relationships have been described mathematically; their interpretation was based on geophysical and geochemical factors. One can hope for future discovery and determination of the actual mechanism responsible for the observed relationships. It would then appear to be possible to evaluate the presumed radiation hazard from contamination of the seas and oceans. The capability of observing artificial and natural radioactive tracers now existing in nature should be used as an instrument for studying geophysical and geochemical processes. The data obtained and the methods developed for ensuring radiation safety are being transmitted to SEV member countries for future use in designing projected atomic power stations and in the treatment of radioactive wastes.
