Appl Radiat Isot. 2011 Oct;69(10):1554-9. doi: 10.1016/j.apradiso.2011.06.016. Epub 2011 Jul 13.

Abstract

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.
