Nuclear Chemistry and Radiochemistry

oral presentation

Long lived anthropogenic alpha-emitting radionuclides have been, and stiil are, released in the environment by nuclear weapon tests, nuclear accidents, fuel reprocessing operations and nuclear power plants decommissioning. Among these the most significant are 239,240Pu and 236U. Quantification of releases and tracking their dispersion in the environment has traditionally been the task of alpha...

Nuclear Chemistry and Radiochemistry

oral presentation

Tritium exists rather uniformly in the environment as a result of both natural production by cosmic-ray interaction with the upper layers of the atmosphere and residual fallout from nuclear weapons tests carried out from 1952 till 1980. Naturally occurring tritium mainly reaches the Earth’s surface in the form of precipitation, becoming part of the hydrological cycle. Nowadays, the possibility...
