COMPARISON OF RADON LEVEL CONCENTRATION IN SOILS WITH THE NATURAL RADIONUCLIDES CONTENT IN SOME REGIONS OF IONAIN COASTAL AREA, IN ALBANIA

Abstract

In this study we present the results taken in south-eastern part of the country, in Ionian coastal area. This study is realized into regions, in the some places in Ksamil town and Uji i Ftohte-Qeparo areas. The main sources of radon gas indoors are entirely related to the geological environment. The measurements of Radon can be realized in several ways such as: radon and permeability in soil; measurements of natural radionuclides (40K, 238U, 232Th) on the ground and soil; radon concentration level in water; measurements radon indoor in dwellings; radon level and soil permeability. Measurements (soil and permeability) have been realized using the Luka-s method. Tests have been carried out indoor at short and long measurement, using active defector with time interval 24h-72h and passive radon detectors in 3months time interval, respectively. The level of in soil Radon concentration has values from 10kBq/m3 up to160kBq/m3. From the interpretation of radon level according to Czech Classification, together with permeability of the soils results that in the two studies areas, Ksamil and „Uji i Ftohte- Qeparo“, the radon risk areas are present in 50% up to 60% of the studied area.
