Abstract:

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 the activity level by using a gamma-ray spectrometry. Results: The concentrations of 226Ra, 232Th, and 40K in soil samples, radium equivalent activity (Raeq) for soil, absorbed dose rates, external hazard (Hex) values were determined. No artificial radioactivity (137Cs) was found in these samples. Conclusion: This present study provides a baseline of radioactivity and radiation levels in the proposed nuclear power plant site area at Rooppur. It will be utilized to correlate the radioactivity measured after operation of the reactor.

Radioactivity from Fukushima Nuclear Power Plant

Several inquiries have been made to Ocean Networks Canada with regard to the fate and severity of oceanic contamination from the leakage of radioactive material into the Pacific Ocean as a result of the March 2011 damage to the Fukushima Dai-ichi Nuclear Power Plant (FNPP). There are on-going studies and assessments of the impacts on the ocean, primarily by the World Health Organization (1) [2]...

Radiological Hazard Resulting from Natural Radioactivity of Soil in East of Shazand Power Plant

Introduction: Nuclear radiation is potentially harmful to humans and soil contamination with radionuclides is the main source of human radiation exposure. These radionuclides can., enter to human body through the food chain. In this study, 34 soil samples were collected from between Arak city and Shazand Power Plant over 20 km length and analyzed. Materials and Methods: The specific activities ...

Radioactivity level of soil around a coal-fired thermal power plant of northwest China

Background: The activity concentrations of natural radionuclides in soil around a coal-fired thermal power plant of northwest China were investigated for assessing the radioactivity level. Materials and Methods: Soil samples were collected around the coal-fired thermal power plant and their radioactivity levels were determined using gamma ray spectrometry. Radiation hazards were assessed by rad...

Environmental releases of radioactivity and the incidence of thyroid disease at the Ignalina Nuclear Power Plant.

The Ignalina Nuclear Power Plant consists of two Russian-made RBMK-1500 reactors. The plant uses Lake Druksiai as a natural reservoir for cooling water. Within the framework of the revised radiation dose limitation system, site-specific routine release conversion factors and maximum annual effective doses for the dominant radionuclides and pathways were evaluated for both atmospheric and aquati...
