background: due to the presence of radioactive minerals such as monazite, the beach sand of the west coast of kanyakumari exhibits high natural background radiation. hair is a good indicator of radionuclides in the human body. an attempt is taken to measure the 210po activity in human hair samples and the factors affecting it. material and methods: 210po activity was analysed in 47 individuals ...

The aim of the study was to determine activity concentration natural radionuclides (226Ra, 210Po, 228Ra and 40K) artificial radionuclide 137Cs in muscle marine fish species most consumed city São Paulo evaluate annual effective dose due consumption fish. Samples were collected supermarket chain Extra Carrefour distribution center CEAGESP. Six selected among available city: anchovy, tuna, dogfis...

In this paper, we present some results of shell-model calculations employing effective interactions derived from the CD-Bonn free nucleon-nucleon potential. These concern 18O, 134Te, and 210Po, and are part of a comprehensive study of nuclei around doubly closed shells. Comparison of the calculated results with experimental data illustrates the degree of accuracy of modern realistic shell-model...

The concentrations of various trace elements and radionuclides have been measured in marine protein concentrates prepared from surface feeding fishes. As with concentrates prepared from benthic fishes, the 210Pb-210Po pair are the most significant radionuclides present. Concentrations of stable Pb, Co and Ag in certain concentrates are sufficiently high to contribute substantially to estimated ...

OBJECTIVES To identify public perceptions of the risk to health after the poisoning of Alexander Litvinenko with polonium-210 (210Po) in London and to assess the impact of public health communications. DESIGN Cross sectional telephone survey and qualitative interviews. SETTING London, United Kingdom. PARTICIPANTS 1000 people completed the cross sectional survey and 86 potentially exposed ...

This article presents the results of studies content natural (228Ra, 226Ra, 232Th, 40K, 210Po, 210Pb, 238U) and technogenic (137Cs, 90Sr) radionuclides in drinking water from centralized (wells) decentralized supply sources observation area Belarusian NPP, performed 2016 to 2020 within framework radiation hygienic monitoring at stage construction NPP.

The richest uranium ore bodies ever discovered (Cigar Lake and McArthur River) are presently under development in northeastern Saskatchewan. This subarctic region is also home to several operating uranium mines and aboriginal communities, partly dependent upon caribou for subsistence. Because of concerns over mining impacts and the efficient transfer of airborne radionuclides through the lichen...
