“…The building materials may also have low concentration of radon precursors or/and low radon exhalation. This result is in contrast to what was observed in a similar study conducted in Amman (Jordan) where some age dependent variations in indoor concentrations were reported in kindergartens (Kullab et al, 1997). However, Kullab et al (1997) also indicated that the classrooms in the older buildings were relatively smaller in size, have cracks in the floors and walls, and have relatively poor ventilation compared to new kindergartens.…”

“…The high indoor radon levels are associated with a number of factors including soil porosity, uranium content of the soil, building material, mode of construction, indoor air characteristics, wind speed, and ventilation conditions. The variability of these factors accounts for the large range of the radon levels measured in dwellings [1][2][3][4][5][6].…”

An indoor radon survey has been carried in 120 schools situated in four districts of the Punjab province, namely Attock, Chakwal, Jhelum, and Rawalpindi. In each season, a total of 360 CR-39-based radon detectors were installed in the selected schools. After exposure the detectors were etched in 6M NaOH at 80°C solution for 16 h and tracks densities, which are related to the radon concentration, were measured. Indoor radon concentration varied from 18 ± 7 to 168 ± 5 Bq·m-3 with an average value of 52 ± 9 Bq·m-3. High indoor radon concentration values were found in the summer season, whereas lower values were recorded in autumn season. The mean annual radon effective dose equivalent was estimated to be 0.49 mSv per year. Present indoor radon concentration values are higher than that of the world average value of 40 Bq·m-3, but lower than the action level recommended by the ICRP.

“…These two mechanisms are affected by many factors including the properties of the soil (Tauner, 1964). Radon emanation and migration in the Earth and the atmosphere have been the subject of numerous studies, in Jordan Kullab et al, 1997;Al-Bataina, 1999;Al-Bataina and Lataifeh, 2000;Abumurad and Al-Tamimi, 2001;Al-Bataina and Abu-Kharma, 2004) (Holkko and Liukkonen, 1992;Duenas et al, 1997, Vaizoglu andGüler, 1999;Sun et al, 2004). The aim of this study is the measurement of radon concentration levels in soil covering different rock formations, in Deir Abu-Said region, Jordan, its relationship with depth and its seasonal variations.…”
