Abstract. Bayesian source reconstruction is a powerful tool for determining atmospheric releases. It can be used, amongst other applications, to identify point releasing radioactive particles into the atmosphere. This relevant applications such as emergency response in case of nuclear accident or Comprehensive Nuclear-Test-Ban treaty verification. The method involves solving an inverse problem ...

introduction: one of the sources of natural occurring radiation was soils. the purpose of article was to determine soil pollution by radiation absorbed dose rate, radium equivalent activity, external hazard index, annual gonad dose equivalent and annual effective dose equivalent. methods & materials: the soil samples was located in chahbahar city in blouchestan of iran, was chosen for studying ...

background: the concentrations and distributions of natural and anthropogenic radioactive materials in soils of the site of rooppur nuclear power plant (rnpp) were investigated with the aim of evaluating the environmental radioactivity and radiation hazard. materials and methods: soil samples were collected from 40 locations in and around the proposed site of rooppur power plant and determined ...
