Measurements of radon concentrations in well waters near the Aksehir fault zone in Afyonkarahisar, Turkey

Abstract

Afyonkarahisar is located in the mid-west Anatolia in Turkey where Aksehir fault zone lies. This earthquake active zone has produced earthquakes in magnitudes from 3.0 to 7.1 in Richter scale. The Rn-222 concentrations in well waters near the fault zone in Afyonkarahisar and its surroundings were determined for the first time. Samples were studied with a Packard Tri-Carb 2770TR/SL model liquid scintillation analyzer. The measured values ranged from 0.7 to 31.7 Bq/L
