Investigation of Radon Concentrations in Pamukkale-Turkey

Radon is an inert gas produced by the radioactive decay of radium with a half-life of 3.81 days. Radon is the largest source of natural ionizing radiation and every 2.6 km² of surface soil, to a depth of 15 cm, contains approximately 1 gram of radium, which releases radon in small amounts to the atmosphere. On a global scale, it is estimated that 91 TBq of radon are released from soil annually. In this work, the radon concentration in soil gas, which is transported from soil (1 m depth), is measured at five points in Pamukkale and its neighbourhood.
