Abstract:
SAM 940TM detector has been used to detect and identify the radioactive isotopes (Radio - Isotope Identification (RIID)) at low levels of gamma rays emitted from food materials.Six samples of fresh milk have been pick out for six locations in Basrah. Ten samples of imported milk powder have been taken into account. Ten samples of lentils, rice, coffee and tea have been taken into account.Eight samples of mineral water, one of distilled water and one sample of piped water; the last one has been picked out from the net distributed water at physics department building in college of science university of Basrah.The results of our study show that, the annual effective dose for the radioactive potassium ????40 in food materials of the highest value. For local fresh milk is (0.216,0.529)mSv/y for adults and children respectively. It is of these samples have been taken from Zubair city, and its less value is (0.076,0.186)mSv/y for adults and children respectively. These samples have been taken from Abuo Al Kasseb. As for the imported milk powder, the highest value is (0.556,1.349) mSv/y for adults and children respectively. The sample is related to Al - munash milk from New Zealand, and less value is (0.272,0.660)mSv/y for adults and children respectively. The sample is related to modhash imported milk powder from Oman.For rice, the highest value is (0.303,0.636) mSv/y for adults and children respectively. The sample is related to Mahmood rice from India, and less value is (0.149, 0.313) mSv/y for adults and children respectively. That is for Galaxy rice imported from India.As for lentils, the highest value is (0.029 ,0.061) mSv/y for adults and children respectively. The sample is related to Wade al akdar lentils from Syria, and its less value is (0.020,0.042)mSv/y for adults and children respectively for Urbak lentils imported from Tukey. For water, the highest value is (0.189, 0.398) mSv/y for adults and children respectively for distilled water and Janaan drinking water from Baghdad. Its less valueis (0.183, 0.385)mSv/y for adults and children respectively for Aquafina drinking water imported from Kuwait.For coffee, the highest value is (0.041) mSv/y for adults for two samples from Brazil and one sample from Spain and other produce from Poland. Its less value is (0.019)mSv/y from European Union production. For tea, the highest value is (0.019, 0.039) mSv/y for adults and children respectively for Jant almunaash and Gazalian samples tea, its less value is (0.008,0.015)mSv/y for adults and children respectively for Alwaza, Mahmood and Baiet alteb samples tea imported from Sri Lanka.The annual effective dose of Iodine ????131 , Cesium ????????134 and Cesium ????????137 in lentils, rice, coffee, tea, mineral water, distilled water and piped water have been carried out and the results are listed in thesis.
