تحديد تركيز غاز الرادون و الثورون في عينات من أهوار المنطقة الجنوبية باستخدام تقنية كواشف الأثر النووية الصلبة

Abstract EN

many samples of water ,sediment and plant have been collected from southern marshes of Iraq to determine radon concentration Long-term technique for alpha particles emission with solid state nuclear track detectors (SSNTDs) Type CR-39 and LR-115 type II were used in closed cylinder technique.

Each sample is placed in a closed cylinder plastic container.

The result showed that radon concentration in sediment samples were ranged between minimum value (872.457 Bq.m-3 ) in Al-chebaish marsh and maximum value (4436.243 Bq.m-3) in Al-hawizah marsh which situated in the allowed level of radon concentration in soil.

The radon concentration in water samples were ranged between minimum value (315.471 Bq.m3) in Al-chebaish and Al-hawizah marsh and maximum value (1744.914 Bq.m-3) in Al-hamar marsh which situated in the allowed level of radon concentration in water.

The radon concentration in Beach sand samples were ranged between minimum value( 315.471 Bq.m3) in Al-hamar marsh and maximum value (3415.871 Bq.m3) in Al-hawizah marsh.

In general we found that the radon activity concentration in sediment ,water and plant under studies are in the range of allowed level .
