Determination of radon concentrations in soil around al-Tuwaitha site using CR-39 detector
In this work radon concentration in 37 soil samples collected from 17 regions surround the (Al Tuwaitha) were measured by using solid-state nuclear track detector (SSNTD.s) CR-39 with natural exposure of one month, and by comparison with standard samples. The radon concentration in the soil samples...

| Summary: | In this work radon concentration in 37 soil samples collected from 17 regions surround the (Al Tuwaitha) were measured by using solid-state nuclear track detector (SSNTD.s) CR-39 with natural exposure of one month, and by comparison with standard samples. The radon concentration in the soil samples was about (9.583 ± 0.369
28.029 ± 0.631) Bq/m3 in locations one (Rotate Salman) and eight (An area agricultural near high-voltage towers) respectively, with rate of (20.939 ± 0.541) Bq/m3. The specific activity of radium (Ra) dissolved during generate radon were ranging between (9.857 – 3.37) Bq.kg-1, with rate of (7.393) Bq.kg-1, surface emission of radon gas rate in the soil was found between (0.144 – 0.422 Bq/m2.h) with rate of (0.314 Bq/m2.h) and their mass emission of radon gas rate has the highest value of (0.016 Bq / kg . h) and lower value (0.005 Bq / kg . h) with rate of (0.012 Bq / kg . h. These results are within the acceptable limit
