Abstract :The radon area exhalation rate and mass exhalation rate of the soil samples collected from five different depths from soil surface with 20 cm intervals of a construction site at Kütahya, Turkey was determined by using the E-Perm detectors. Accumulator method is used to determine the radon concentration of the soil samples. Radon concentration of the soil samples were measured between 34 ± 4.4 Bq.m-3 to 86 ± 6.8 Bq.m-3 with an average value of 48.6 ± 5.1 Bq.m-3 for five days analysis time. Radon area exhalation rate of the soil samples were calculated between 163.7 ± 21.3 and 413.1 ± 32.6 mBq.m-2.h-1 with an average of 233.2 ± 24.4 mBq.m-2 .h-1. Radon mass exhalation rate of the soil samples were found between 32.9 ± 4.3 to 83 ± 6.6 mBq.kg-1.h-1 with a mean value of 46.9 ± 4.9 mBq.kg-1.h-1. The radon contribution to the indoor air from soil samples is estimated as 6.5 Bq.m-3.
