Radon222 levels were measured using the solid state nuclear track detector (CR-39). 21 dosimeter containing CR-39 placed in seven different sites in Al-Kerak region; Mutah, Adder, Madden, Barada, Al- Smakia, Rakeen, and Al-Haweya. It was found that Barada and AL-Smakia possessed the highest Radon levels 356.891 Bq/m3 and 353.379 Bq/m3 respectively. The lowest value of Radon concentration was 100.89Bq/m3 and found in Madden. Also Radon levels was measured in 9 different types of building materials; Ordinary Portland Cement; O.P.C, Aggregate (Lime stone), Marble, Sand, Fly Ash, Oil Shale, Soot, Slag and Zeolites). It was found that Marble contains a high level of Radon222 (96.169 Bq/m3) and Oil shale has the lowest value of Radon level equal to 9.587Bq/m3. The detected CR-39 were inspected and analyzed at Jordan Atomic Energy Agency using high accuracy Optical Microscope. Uncertainty calculation were made on the whole data taken from the Agency to figure out the accuracy of the results. A comparison has been made between the results comes out from this work and the others results regard some places and some construction materials.
