Past tests of nuclear weapons in the atmosphere, nuclear energy facilities and tritium of natural origin are main sources of tritium in the environment. Thanks to its presence in environment and its favourable properties, tritium is used as a radiotracer.
Development of selected radionuclides in surface water in the vicinity of the Temelín Nuclear Power Plant in the period 1990–2016
The paper presents results and interpretation of long-term monitoring of occurrence and behaviour of radioisotopes 3H, 90Sr and 137Cs in surface water in the vicinity of the Temelín Nuclear Power Plant. 3H, 90Sr and 137Cs originate predominantly from residual contamination due to atmospheric nuclear weapons tests and the Chernobyl disaster in the last century.
Cooperation of Water Research Institute and Povodí companies, state enterprise within the framework of radiation monitoring network of the Czech Republic
The paper sums up the legislative framework and cooperation of TGM Water Research Institute and Povodí companies, state enterprises.
Temporal and spatial changes in concentrations of selected radionuclides (tritium, radiostrontium and radiocaesium) were assessed in the parts of the Vltava and Elbe river basins affected by the operation of the Temelín Nuclear Power Plant.
In connection to the assessment of a radiological event, the procedure of rapid determination of the gross beta activity in water was proposed and validated. In cooperation with the radiological laboratories, the method has been tested in practice.
