90Sr has a long half-life, strong radioactivity, and high mobility. The removal of radioactive strontium from the water environment is great significance to human safety sustainable development nuclear energy. In this study, two-dimensional rare earth phosphate K3Nd(PO4)2 efficiently captured Sr2+ ions in aqueous solutions. At room temperature, adsorption isotherm, kinetics, pH dependence exper...

The distribution of natural (at the level global background) and technogenic radionuclides in groundwater industrial zone Sosnovy Bor town, where several nuclear power facilities are operating, was analyzed. main recorded samples cesium (137Cs), strontium (90Sr), tritium isotopes. first two aquifers from surface subject to contamination: Quaternary upper Lomonosov aquifer. Based on extensive ma...

The migration of radionuclides from radioactive waste into the environment poses a public safety concern. Thus, long-term assessment for near-surface disposal sites in South Korea entails providing reasonable assurance that annual radiation dose exposure radionuclide release repository biosphere will not exceed regulatory limit 0.1 mSv/yr. At first site Gyeongju, concrete was crucial component ...

The article presents the results of assessment absorbed dose rate from incorporated radionuclides 137Cs and 90Sr in body wild boar living an area with different levels radioactive contamination. internal irradiation was evaluated for muscle bone tissue boar. During assessment, it assumed that uniformly distributed are equilibrium conditions, concentrated animal, during year concentration is to ...

The aim of the present study was to investigate the inhibitory effects of 90Sr-90Y β-irradiation in a rat model of alkali burn-induced corneal neovascularization (CNV). Alkali burn-induced CNV was induced in the right eyes of 30 female Wistar rats, which were randomly divided into the following three groups (n=10/group): i) The alkali burn control group, which received a balanced salt solution ...

Radioactive wastewater contaminated with 137Cs and 90Sr are produced at different stages of the nuclear fuel cycle. Transferring these radionuclides to a stable solid matrix is crucial for safe management long-term storage. Sitinakite Crystalline silicotitanates (CSTs) among most selective mineral ion exchangers Cs and/or Sr depending on pH medium CST chemical composition (Nb doping). To better...

Strontium-90 concentration was measured in human bones and teeth collected in Greece during the period 1992-1996. One hundred and five bone samples, mainly cancellous bone, and 108 samples, taken from a total of 896 individual teeth were processed. Samples were classified according to the age and sex of the donors. Samples were chemically pre-treated according to a specially devised method to e...

In order to study the role of natural killer (NK) cells during the early period of Leishmania infection, BALB/c mice were selectively and permanently depleted of NK cells by injection with 90Sr and subsequently infected with Leishmania (Leishmania) amazonensis (HSJD-1 strain). 90Sr is known to selectively deplete NK cells, leaving an intact T- and B-cell compartment and preserving the ability t...
