The paper presents the results of research on rare earth elements (REY) and selected radionuclides in barren rocks deposited a heap at mine belonging to Polish Mining Group (the largest producer hard coal EU countries). maximum concentration REEs determined silstones was 261.6 mg/kg sandstones 221.2 mg/kg. average uranium thorium content 6.8 11.6 mg/kg, respectively. On other hand, samples burn...

Activated corrosion products (ACPs) may represent a significant source of radiological hazards in nuclear fusion reactors. Corrosion and erosion phenomena mobilize activated materials which are transported by the working fluid regions cooling system accessed worker personnel. Predicting contaminant transport tokamak circuits benefit radiation exposure assessment, design optimization, waste mana...

This study is aimed at assessing radiation hazards associated with natural radioactivity in common building materials used Ho Chi Minh City, Vietnam. Thirty-six samples from eighteen types of were collected to measure activity concentrations using the gross alpha/beta counting system and gamma-ray spectrometry. The alpha beta ranged 94.7 ? 31.3 1045.1 112.3 Bqkg-1 104.9 4.7 834.4 37.1 Bqkg-1, r...

Activities related to the marine exploration of oil and gas reservoirs tend cause a concentration natural radionuclides in materials. As such, knowledge regarding distribution sedimentary basins with current operations is essential for modeling radiological hazards possible risks site contamination. This study investigated 226Ra 228Ra, radioisotopes from 232U 232Th decay chains bottom sediment ...
