During a normal operational regime of the nuclear power plants (NPPs) equipped with pressurized light water reactors (PWR), 3H and 14C are two biggest contributors to the effective dose of population. While 3H is responsible for the highest dose from all nuclides discharged in liquid effluents, 14C causes the highest dose from the nuclides liberated in airborne discharges. Monitoring of the...
Sorption behavior is one of the most important characteristics of material considered to be used in engineered barrier on the sites for radioactive wastes repositories. One such site in Russia is located near Krasnoyarsk on the Yeniseyskiy site, in the Nizhnekansky rock massive. It is designed for intermediate and high level radioactive wastes, including self-heating radioactive wastes...
Modern geoecological situation of “Crystal” peaceful underground nuclear explosion (PUNE) area basing on the geochemical and the geophysical sounding data is considered. New data of the contents of radionuclides in surface and underground waters are obtained.
Geophysical transient electromagnetic sounding, in other words - time-domain electromagnetic sounding method (TDEM) along two profiles...
Radioactive mineral waters (rich in dissolved 222Rn) are highly valued for their medical use. Therefore they have been intensively explored in last years (2005–2017) in the Lusatian and Saxothutingian units of the Bohemian Massif. Springs of radioactive medicinal water are bound up with the Cambrian/Ordovician orthogneisses and Tanvald granite of the Variscan age in the Lusatian unit and...
Hexavalent uranium is a prominent radioactive contaminant in both sediments and aquifers around nuclear activity sites, and poses a potential health and environmental risk to the biosphere. Understanding on the detailed interaction at the solid-liquid interface between uranium and granite is crucial for the safety assessment of high level radioactive waste geological repository in granitic...
After 30 years of accident on the Chernobyl NPP radioactive contamination in 30-km Chernobyl zone is determined by long-lived radionuclides of Cs-137, Sr-90 (with the half-life time 30.1 and 29.1 years, respectively) and alpha-emitting isotopes of Pu-238,239,240 and Am-241, also known as transuranium elements (TUE) (Sokolik 2004; Kashparov et al. 2003).
The overall aim of this article is to...
Artificial reservoir V-17 (Old Swamp) was formed as a result of the construction of dams in 1952 and 1954 (MAYAK Production Association), located in a natural depression relief. Intermediate level liquid radioactive wastes (ILLW) have been discharged to this reservoir since 1949. The water surface area of the lake is 0.13 km2 with the volume of 0.36 Mm3. The maximum depth is 6.5 m with the...
