The seasonal variations of the indoor radon activity concentrations were determined in the 97 dwellings of Trabzon, Turkey. The annual average indoor radon activity concentration varied from 8 to 583 Bq/m³. The average winter/summer ratio of radon activity concentrations was 3.62. The gamma activity concentrations in the soil samples were determined as 41, 38, 443 and 25 Bq/kg for ²²⁶Ra, ²³²Th, ⁴⁰K and ¹³⁷Cs, respectively. The average gamma dose rate in air and the annual effective dose equivalent for outdoor occupancy were calculated as 63 nGy/h and 77 μSv/y, respectively.
在土耳其特拉布宗的97所住宅中测定了室内氡活度浓度的季节变化。室内氡活度浓度的年平均值在8至583 Bq/m³之间变化。氡活度浓度的冬夏平均比值为3.62。土壤样品中²²⁶Ra、²³²Th、⁴⁰K和¹³⁷Cs的γ活度浓度分别测定为41、38、443和25 Bq/kg。空气中的平均γ剂量率和室外居住的年有效剂量当量分别计算为63 nGy/h和77 μSv/y。
