Abstract: The aim of the current study was to measure indoor radon concentration levels
and its resulting doses received by the students and staff in schools of the directorate of
education in the north of Hebron region- Palestine, during the summer months from June to
September (2018), using CR-39 detectors. In this study, a total of 567 CR-39-based radon
detectors were installed in the selected schools. The average radon concentrations were
found to be 90.0, 66.5, and 58.0 Bqm-3 in Halhul, Beit Umar and Alarrub camp schools,
respectively. Based on the measured indoor radon data, the overall average effective dose
for the studied area was found to be 0.31 mSvy-1. Reported values for radon concentrations
and corresponding doses are lower than ICRP recommended limits for workplaces. The
results show no significant radiological risk for the pupils and staff in the schools under
investigation. Consequently, the health hazards related to radiation are expected to be
negligible
