The selected schools were identified according to them being old and new and there places around the city. The radon activities were measured 15,95 ± 6,68 Bq\m3 in Vali Aydın Arslan Primary School, 23,46 ± 8,76 Bq\m3 in Girls? Vocational High School (Kız Meslek Lisesinde), 58,98 ± 19,77 Bq\m3 in Gazi Paşa Primary School, 33,78 ± 11,86 Bq\m3 in Industrial Vocational High School (Endüstri Meslek Lisesinde), 11,87 ± 5,53 Bq\m3 in Ali Fuat Darende Primary School, 36,94 ± 12,85 Bq\m3 in Mehmet Akif Ersoy Primary School, 18,03 ± 7,24 Bq\m3 in Isfendiyarbey Primary School.In the frame of International Nuclear Energy Agency basic Security Standards (IAEA-BSS) the advised radon levels for houses is 200-600 Bq/m3. According to the Turkish Nuclear Energy Institution?s (TAEK) Radiation Security Regulation the limit value permitted for houses is 400 Bq/m3, 1000 Bq/m3 for workplaces (TAEK 2009). The average radon activities measured in schools were under the value of the permitted International and Turkish standards.
