  • Enrichment of 210Po and 210Pb in the Padubidri environs of Karnataka

    The activity concentrations of natural radionuclides, viz 210Po and 210Pb, in soil samples of Padubidri in the coastal Karnataka, the site for the proposed coal-based thermal power station, were measured using a ZnS (Ag) alpha counting system to establish baseline data on radioactivity levels in the environment of the region. Soil samples were collected at different sampling stations and analysed ...

  • Analysis of reconstruction of the composition of liquid radioactive waste released into the Techa River in 19491956

    An analysis of archival data of liquid radioactive waste samples and Techa River bottom sediments was made, taking into consideration the radiochemical methods for extraction and beta-emitting radionuclide activity measurements existing in the early 1950s. It was stated that the radionuclide composition of the routine and accidental liquid radioactive waste releases in 19491951 corresponded to ...

  • Determination and use of scaling factors for waste characterization in nuclear power plants

    Disposal of radioactive waste requires knowledge of its radioactivity content in terms of the concentrations of specific radionuclides. This information is used by the repository operator and/or regulator to track radionuclide inventories and concentrations, which are generally limited by the repository safety assessment and resulting operating licence. It is normally the responsibility of waste ...

  • Radioactivity and radiation hazard evaluation in the environment of coastal Kerala, India

    Systematic investigations on the radiation level and distribution of natural radionuclides in the soils and sands of coastal Kerala were carried out to evaluate the radiation hazard. The gamma-dose rate in the high background area of coastal Kerala is exceptionally high compared with normal background areas. The activity concentrations of 232Th, 226Ra and 40K in soil and sand samples of coastal ...

  • Counting solutions LSC technical tips from PerkinElmer

    The advance of the nuclear industry in all its forms coupled with growing concerns for possible environmental contamination has led to an increased interest in the quantification of radioisotopes in the environment. Radionuclides currently present in the environment originate from a variety of sources such as fallout from nuclear weapons testing, and in discharges from both nuclear and ...

  • Polonium-210 in cigarette tobacco

    Tobacco and tobacco smoke contain minute amounts of some natural radionuclides such as 210Pb and 210Po, which are carcinogens. Intake of these radionuclides results in an increase of radiation doses to lung cells and tissues. Samples of the most frequently smoked cigarette brands were collected from the local market of Riyadh City, Saudi Arabia. Activity ...

  • Examination of hot particles originating from damaged fuels at the nuclear power plant Paks

    Radioactive samples can contain radionuclides not only in homogeneous form, but also as 'hot' particles. With the characterisation of these high activity particles, information about the source of the samples can be obtained. The examination of hot particles is important in the case of environmental as well as nuclear samples; this paper details the analyses of particles originating from ...

  • Pb–210 irradiation dose estimation for inhabitants living in high natural background areas on Pernambuco/Brazil

    This work was designed to: (a) determine 210Pb concentration in human urine samples of inhabitants of two regions with high natural radiation in the state of Pernambuco - Brazil; (b) estimate radiation dose in bones as a result of this radionuclide incorporation. For this, urine samples of healthy and non–smoker subjects were studied. Pb–210 was separated by ion–exchange resin ...
