English Abstract
Indoor radon has been recognized as one of the health hazards for mankind because long-term exposure to radon increases the risk of developing lung cancer.
In this study, we report on the radon concentration levels, in the houses of Rafah city during summer season of the year 2016 using the CR-39 track detectors.
Passive diffusion Radon dosimeters containing CR-39 solid state nuclear track detectors of good quality were used to measure Radon and its daughter's concentrations throughout Rafah city.
Our sampling strategy was to distribute the dosimeters in houses in Rafah city (Tal El Soltan , Balad(Rafah camp) and El Genena) at different geographic parts of the region.
These dosimeters were distributed in bedrooms, living rooms and kitchens.
The (150) detectors were left for three months during the period from June to August of 2016.
The collected detectors were chemically etched by using NaOH of (6M) concentration at temperature 700C for a period of 5 hours.
Each detector was counted visually using an optical microscope with power of (40*10).
Tracks in the three distinct regions of Rafah city were observed, through the area (1cm2) of the detector.
The average Radon concentration at all the regions was found to be 73.8 Bq/m 3 (1.99 pCi/l) with a range of values between 16.5 and 150.4 Bq/m3 (0.44 and 4.06 pCi/l),and average standard deviation of 15.1 Bq/m3.
The average indoor radon concentration obtained was below the indoor radon concentration action level (148 Bq/m3) recommended by Environmental Protection Agency (EPA).
The results obtained in this work are quite limited and should only be considered as indicative of the variability in radon concentration that expected in normal building in Rafah.
However, in spite of this limitation, certainly this study provides an extrapolations about radiation concentration in general form in Rafah city, and indicates the health effects that radiation might cause in future, from environmental point of view.
