Abstract

Radioactivity can be found in different degrees in the environment, Terrestrial gamma radiation is one of the major outdoor radiation exposures to the general public, depending on the activity and concentration of the radionuclides being handled, the main concern being exposure to natural radioactivity doses and external exposure rate. This research presents a measurement of the natural radioactivity of Ra-226, U238-, Th232- and K40- for 8 grasses samples around one of the old weapons warehouses located in the Al-Meshal, Libya, using a sodium iodide (NaI) detector. The results showed that the concentration of radioactivity for 238U ranges from [(65.32±6.06) to (85.59±6.77)] Bq/Kg. The mean activities of 226Ra ranges from [(60.02±0.13) to (84.03±0.13)] Bq\Kg, for 232Th ranges from [(66.09±3.07) to (86.42±1.30)] Bq/Kg. For 40K ranges from [(424.42±14.78) to (484.49±18.24)] Bq/Kg, all samples were found to be slightly higher than the world average values 20 ,50, 15, and 420 Bqkg−1, respectively. for uranium, radium, thorium and potassium (UNSCEAR 2010). For Radiological risk (radium equivalent, internal and external hazard indices), it was found that these samples have lower or within the recommended limits internationally.
