Abstract
The present research aims to estimate the concentrations of natural radioactive gamma rays and radon gas in Sadat City's surface and subsurface sediments by using active tools for field measurements. The gamma-dose rate in (µSv/h) directly assessed by using Digilert200 instrument in situ. Whileradon gas (Rn-gas)is estimated in situ by using CR-39. The gamma-ray results range from 0.007 at stations number 25 and 33 to 0.024 at station number 6 and 54, a narrow range was obtained. These values are great far less than the permissible value recommended by the IAEA, 10 (µSv/h). The Rn – gas measures ranged from 0.430±0.351 station no (SI-30) to 4.635±0.930 station no (SA-68). These values are very small compared with the average world values for Rn- gas concentrations ICRP -60. The results of investigated sitesindicate thatthere are no expected potential environmental risks resulting from natural radioactive gamma-rays and Rn-gas in Sadat City surface and sub-surface soil. Add to that, present human activities such as industrial and agricultural have no effects on the radioactive percentage.
