Abstract

The aim of this study is to
determine the concentration of Radon and its annual effective dose at the Nigde
Museum and in a number of historical places namely the Sungur Bey, the
Alaeddin, the Disari mosque and the Ak Medrese Culture House in Cappadocia,
Nigde, Turkey by using a nuclear track detector CR-39 to ascertain how much
Radon concentration affects the people who are working in or visiting such
places. Nuclear track detectors CR-39 were used for measurement for 132 days at
the Nigde Museum, and for 63 days in the historical places. The exposed nuclear
track detectors were then sent to the Sarayköy Nuclear Research and Training
Center (SANAEM) to determine of Radon-222. The average Radon concentration
results obtained for the Nigde Museum, the Sungur Bey, the Alaeddin, the Disari
mosques and the Ak Medrese Culture House were 13.0±2.94 Bq/m³,
31.67±3.86 Bq/m³, 52.0±5.72 Bq/m³, 42.67±19.34 Bq/m³
and 31.0±4.55 Bq/m³ respectively. The average effective dose of
Radon was calculated for the Nigde Museum, the Sungur Bey, the Alaeddin, the
Disari mosques and the Ak Medrese Culture House in Nigde and was found to be
approximately 0.137 mSv/y, 0.062 mSv/y, 0.103 mSv/y, 0.084 mSv/y and 0.327
mSv/y respectively
