“…In contrast to the results derived for 137 Cs and 90 Sr, the trends in the concentrations of 3 H at unaffected (reference) and affected river sites were greatly different. In the period 2000-2013, the mean 3 H concentration at the reference sites was 1.1 Bq/l.…”

The paperfocuses on an analysis of the results of long-term monitoring of the concentrations of 137 Cs, 90 Sr and 3 H in hydrosphere in the vicinity of Temelín Nuclear Power Plant (Temelín plant). The radionuclides were monitored in surface water, river sediments, aquatic flora and fish species. The main objective of the study was to analyze and integrate all of the knowledge on concentrations and behaviour of these radionuclides, which originate mainly from residual contamination, in order to assess the impacts of Temelín Nuclear Power Plant on hydrosphere in these indicators during its standard operation and possible accidents. The radionuclides were analyzed in terms of spatial and temporal variability in their concentrations and their inflows and outflows, mainly into and from Orlík Reservoir. The analysis included standard radioecological characteristics, which were applicable for assessing long-term development and behavior of radionuclides in the environment affected by their possible accidental releases on the territory of the Czech Republic or outside this territory. For all of the components of the environment, the concentrations of 137 Cs and 90 Sr which were used for calculation of their effective and ecological half-time, were decreasing. For 137 Cs in surface water and fish, the rates of the decrease in the first and second monitoring period were different. The rate of the decrease in 90 Sr concentration was invariable. The results of the monitoring showed that 86% of suspended solids and 62% of 137 Cs inflowing into Orlík Reservoir accumulated in the reservoir while accumulation of 90 Sr was not substantiated. Outflows of 137 Cs and 90 Sr activities were assessed in relation to their concentrations that were accumulated in individual basins until 1986 consequently to Chernobyl accident and tests of atmospheric nuclear weapons. The results for the whole area of the Vltava, Lužnice and Otava River basins upstream from the Vltava River at Solenice showed that during the period 1986-2013 only 0.49% of 137 Cs activity and 3.6% of 90 Sr activity that accumulated in the basins were washed and flowed out from the area. Distribution coefficients derived from summary analysis of sediments and concentration factors for biota were calculated. Concentrations of 3 H in river sites not affected by Temelín plant were slowly decreasing and their values were substantially below those from the sites affected by the plant.

“…Extensive literature has been published on tritium measurements in rivers and river basins used to estimate the residence time of ground water. Recently published papers have provided tritium concentration values in surface waters, in ground waters and also the average tritium concentration measured in precipitation, which did not exceed 2 Bq L −1 or 15 TU (1 Tritium Unit (TU) = 0.11919 Bq L −1 , corresponds to 1 3 H atom per 10 18 H atoms) [14][15][16][17][18][19][20][21][22][23][24][25][26]. A detailed presentation of these values together with the relevant references is contained in Table 1.…”

“…Based on the daily urine tritium concentration data, the effective dose produced by the daily dose can be estimated using formulas (3) and (4). The effective dose on the last monitoring day on March 28 was 14.413 mSv, and the last dose is estimated to be 0.123 mSv.…”

“…With the continuous development of nuclear energy, the levels of tritium in the environment are increasing, and considering that tritium is affecting the health of humans, it is gaining more attention. 1 -3 In particular, with the development of controllable thermonuclear fusion research at home and abroad, the commercial operation of controllable thermonuclear fusion reaction devices in the near future is also within sight. Such reactors produce approximately 10 4 times the amount of tritium produced by the fission reactors currently used in nuclear power plants; consequently, even if only some of this tritium is released into the environment, tritium emissions would still increase by hundreds of times.…”

In this study, we aimed to investigate the damaging effects and clinical therapy of internal contamination with tritium to provide information and gain experience for medical treatments in case of an emergency due to a nuclear accident. Histories were taken by several doctors who observed and recorded the clinical symptoms of the patient described herein. The general health situation was evaluated by laboratory and equipment analyses. Tritium concentrations in the urine were estimated according to relevant standards during the monitoring period using a liquid scintillation counting method. Clinical observation revealed that the patient had symptoms of mild asthenia and sleep disorder with improvement after appropriate treatment. The last committed effective dose was determined through measurement of the urine tritium concentration and dose estimation and was estimated to be 0.123 mSv; the total effective dose was 14.536 mSv. The medical treatment and dose estimation in this patient with tritium contamination were successful and can provide a reference for similar cases in the future.
