Outdoor Radioactivity and Health Risks for Nurdağı,Turkey

In order to determine the outdoor gamma dose rates, the study area was separated to 35 sampling stations with approximately 3 km distance. Measurings were done in 3 different locations for each sampling station. The average of these 3 measurements was taken and was specified as outdoor gamma dose rate for sampling stations. The outdoor gamma dose rates were measured by Eberline smart portable device (ESP-2) connected with an SPA-6 model plastic scintillation detector. Measurements were taken in air for two minutes at 1 m above the ground and the gamma dose rates were recorded nGy/h. The average outdoor gamma dose values measured at 35 locations measured per hour in the air at an altitude of 1 m was 59.4 nGy/h. The average annual outdoor gamma dose is determined to 72,8 μSv for Nurdagi province.
