The radio nuclides in piping drinking water, cultivated soil and consumed food material from Zahedan city

The ionizing radiation can affect the human health and the life of other organizes living things in short time, especially when the dose of radiation exceed the ICRP standard. The amount and type of radioactive matter were not known in water, soil and food products of Zahedan. Therefore this study was aimed to survey the safety of such materials for the human being. Five different places in Zahedan city were chosen for sampling from water, soil and food materials and concentration and type of radionuclide were determined. Sieving, drying and mix Turing were amongst the method utilized for suitable preparation of the materials. The results show no existence of any artificial radio nuclides. However there were some natural radionuclides such as K-40, U238, Th232 and Ra226 in different dosages in the examined samples. The study confirmed that there is no risk of radio nuclides exposure with regard to the soil, water and food materials in Zahedan
