Cost-effective methods are needed to identify the presence and distribution of tritium near radioactive waste disposal and other contaminated sites. The objectives of this study were to (i) develop a simplified sample preparation method for determining tritium contamination in plants and (ii) determine if plant data could be used as an indicator of soil contamination. The method entailed collec...

Nuclear weapons making and testing, operation of enterprises of the nuclear industry, of military and civilian nuclear fleet, as well as peaceful nuclear explosions – all that led in the USSR to release of radioactive products into the environment. In some parts of the FSU radioactive contamination exceeded permissible levels. The necessity of remediation of such territories became evident. The...

A coordinated research project initiated by the IAEA on “Radiochemical, chemical and physical characterization of radioactive particles in the environment” was conducted by a research group representing twelve countries (Brazil, Denmark, Finland, Hungary, Israel, Kazakhstan, Norway, Russian Federation, Spain, Ukraine, USA) and the European Commission Joint Research Centre Institute for Transura...

Labeling of eukaryotic cells with radioactive nutrients is a popular method in the detection of biomacromolecules. Less popular and much ignored is the radioactive contamination of cell-culture equipment that usually accompanies this activity. The reason for this contamination is the production of radioactive vapors or gases, either by spontaneous chemical decomposition or through metabolic con...
