Özet |
Internal exposure arises from the intake of natural radionuclides by inhalation and ingestion. Inhalation exposure is mainly caused by alpha and beta radiation from the radioactive radon gas (a daughter product of 226Ra in the 238U series), which emanates from rocks and soils and tends to concentrate in enclosed spaces like houses, and its shortlived decay products (218Po, 214Pb, 214Bi, and 214Po). In this study, the radon concentrations in the outdoor air resulting from the topsoil samples collected from 39 different locations in the Karabük industrial city were determined based on the activity concentration of 226Ra contained in the soil samples. For this purpose, the activity concentration of 226Ra and radon emanation coefficients of the soil samples were measured by gamma-ray spectrometry with the measurement of porosity and true density of soil samples. The radon concentration in outdoor air varied from 31 to 140 Bq/m3 with an average of 71 Bq/m3. Annual effective dose due to inhalation of radon estimated for adults varied from 291 to 1330 µSv/y with an average of 974 µSv/y. The average value of annual effective dose is lower than the recommended limit of 1000 µSv/y. |
