88. Radon measurements indoors, in soil and in water by track detectors and/or by Geiger-Muller counters

Invited talk

The large radon concentrations of the home’s indoor air can be caused essentially by two sources, the soil or the water supply. A thoroughly investigation of the indoor radon may require the measurement of radon indoors, in soil, in water respectively. With existing technologies, these radon measurements require a variety of different devices and sampling procedures. Finally, a new generation...

Abstract
In the Fukushima-Daiichi Nuclear Power Station (FDNPS) accident that occurred in March 2011, existing monitors for radioactive materials in the atmosphere are expensive and often large, so they could not be deployed in a wide range of locations after the accident. Thus, there are few data on internal exposure doses of residents after the FDNPS accident. On the other hand, small and...

32. Site-specific dose conversion factors for radon progeny based on actual aerosol size distributions at various environments

The ICRP recommended a new dose conversion factor for radon, which is two times higher than the value by the UNSCEAR[1,2]. Therefore, an inhalation dose assessment for radon and its short-lived progenies gets more essential recently. The ICRP also mentioned the importance of the aerosol size distribution in the inhalation dose assessment. Many researchers reported that the inhaled aerosol size...

126. Determination of 226Ra/238U and 228Ra/232Th disequilibrium in surface soils from HBRA, Odisha, India and its radiological implications

Dr Nimelan Veerasamy (Institute for Environmental Sciences)

Naturally occurring radionuclides of terrestrial origin are ubiquitous in the Earth’s crust. The radionuclides which are responsible for the enhanced natural background radioactivity are 238U, 232Th and their decay products. Therefore, it is necessary to monitor the environmental behavior of the naturally occurring radionuclides and radiation patterns in the HBRAs to increase awareness with...
