Measurement of Indoor Seasonal and Regional Radon (222Rn) Gas Activity in Çanakkale (Turkey)

Radon gas, which undergoes radioactive decay, can cause damage to the lung tissue and cancer over time in indoor environments where it is inhaled. gas radioactivity concentrations were measured using CR-39 passive solid state nuclear track detectors (SSNTD) basement ground floor simultaneously summer winter periods 17 dwellings Çanakkale (Turkey). Accordingly, an average of 163.67 Bq.m-3 basements summer, 63.26 floors 148.73 winter, 77.57 winter. In addition, annual effective dose (AEDE) values lifetime risk (ECLR) parameters calculated radon activity concentrations. mean AEDE period found be 4.52 mSv.y-1 1.59 mSv.y-1, respectively. was as 3.75 1.95 mSv.y-1.
