The primary source of radiation exposure for the public in indoors is recognized as the inhalation of radon-222 and its short-lived decay products. When the daughters of radon-222 accumulate in the human lungs, bronchi or trachea, they can cause cells to mutate or die. Therefore, investigating how radon concentration changes over time in indoor environments is crucial for evaluating its impact on populations.
In this study, radon concentrations were determined in some schools in the Tatvan district of Bitlis province using LR-115 detectors. During the spring semester (March-
April-May), the arithmetic mean of radon concentration was measured as 86.82 Bq/m3,
while during the fall semester (September-October-November), it was 137.28 Bq/m3. It was found that the radon concentration was higher when schools, which were not ventilated throughout the summer, resumed education. Additionally, according to measurement results taken from different floors, the arithmetic mean of radon concentration in the ground and basement floors of schools was determined as 122.89 Bq/m3, while it was 99.38 Bq/m3 for the upper floors. It was observed that the radon concentration decreased as one moved from the ground to upper floors.
