  • 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 ...

  • 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 ...

  • Evolution of radiocontamination in the Mediterranean Sea in the period 1985–1995

    Investigations were carried out on several biotic and abiotic samples to determine the environmental radiocontamination of the Mediterranean Sea after the Chernobyl accident. Special emphasis was put on the determination of Cs-137 in the Adriatic Sea. This caesium isotope was the most abundant radionuclide in a wide variety of samples (seawater, sediment, pelagic and benthic species). Attention ...

  • Can chemical treatments to displace radioisotopes influence soil fertility? A laboratory trial

    Soils contaminated with radionuclide pose a long–term radiation hazard to human health through exposure via the food chain and other pathways. Remediation of contaminated soils has become increasingly important. The feasibility to move radionuclides from superficial soil layers to a deeper level using an acid leaching solution was already illustrated previously. As this chemical treatment may ...

  • Activity of 226Ra, 232Th and 40K in riverine environs and evaluation of radiological hazards

    This paper discusses the results of systematic measurement of activity concentrations of 226Ra, 232Th and 40K in riverine samples of river Sharavathi, one of the major rivers of coastal Karnataka in India. Activity concentrations of 226Ra, 232Th and 40K in soil, sediment and rock were measured by Na(I) Tl gamma-ray spectrometry. To assess the radiological hazards of the natural radioactivity in ...

  • 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 ...
