For more than 60 years, the issue of the occurrence and behavior of radioactive substances in water has been dealt with in the Water Management Research Institute. With the observation of natural and artificial radionuclides in the hydrosphere, the team started under the guidance of Dr. Ing. Jaroslav Bulíček.
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.
Traditional conference The Radionuclide and Ionizing Radiation Conference on Water Management took place on 24.–25. May. 4. 2018 at the Clarion Hotel in České Budějovice. Expert guarantor was Ing. E. Hanslík, CSc., (TGM WRI, p. r. i.) and organizational guarantor Ing. V. Bečvář, CSc. (ČVTVHS, z. s.).
This article deals with new Czech Standard 75 7221 Water quality – Classification of surface water quality  and replaces the previous 19 years old standard . It was necessary to take into account actual demands of the surface water protection from two points of view: pollution indicator selection and current environmental quality standards. The range of pollution indicators and limit values of water classification were revised.
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.
Traditional XXIV. Conference Radionuclides and ionizing radiation in water management was held from 2 to 4 May 2016 at the Clarion Hotel in České Budějovice. Professional guarantor was Ing. Eduard Hanslík, CSc. (WRI, p. r. i.) and organizational guarantor Ing. Václav Bečvář, CSc. (ČVTVHS).
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.
