Studies on the Removal of Hydrophilic Radioactive Substances from Radioactive Waste

Mathematical Modelling in Radioactive Waste Leaching Studies

Transport phenomena involved in the leaching of a radioactive material from a composite matrix into surrounding water are investigated using three methods based on theoretical equations. These are: diffusion equation derived for a plane source model, rate equation for diffusion coupled with a first-order reaction and an empirical method employing a polynomial equation. The obtained results are ...

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...

Disposal of Radioactive Waste

Perhaps the most important single problem arising from the increasing use of atomic energy for peaceful purposes is how to dispose of the growing amounts of radioactive waste. Many of its complex aspects were discussed at the scientific conference on the disposal of radioactive waste held by IAEA in Monaco from 16 to 21 November 1959. The conference was organized jointly with UNESCO, with the c...

On Leakage from the Near-surface Radioactive Waste Storage Facility

Maisiagala RADON type radioactive waste storage facility was commissioned in 1963 in a marshy, ecologically sensitive locality, where soluble radionuclides easily can penetrate and migrate with groundwater. To assure the requirements of radiation safety, the analysis of radionuclide leakage from the radioactive waste storage facility is performed continuously. H (tritium, T1/2=12.33 years) is o...
