The Annual Dose for Qena Governorate Population Due to Consume the Animal Products
Proceedings of the 4 th Environmental Physics Conference, 10-14 March 2010, Hurghada, Egypt THE ANNUAL DOSE FOR QENA GOVERNORATE POPULATION DUE TO CONSUME THE ANIMAL PRODUCTS S. Harb, K. Salahel Din, A. Abbady and Nagwa Saad Physics Dept., Faculty of Science, South Valley University, 83523, Qena, Egypt Several kinds of cattle and poultry fodder samples collected from South Valley University and Qena governorate farm, Qena, Upper Egypt were estimated for their natural radioactivity concentrations due to Ra-226, Ra-228, Th-232 and K-40 radionuclides. Twenty nine samples were analyzed by using low-level gamma- spectrometric. Based on radionuclides concentrations in animal fodder and annual consumption rate, the human health risk from irradiation due to indirect ingestion can be assessed. The annual effective dose from these radionuclides, which may reach the local consumer through beef, milk, poultry and eggs consumption have been estimated as 2.7E+00, 1.4E+01, 1.0E-01 and 1.4E-01 µSv/y, respectively.

INTRODUCTION Radiation from natural sources gives more than 80 % of the total exposure received by the average member of a population and a portion of this exposure comes from dietary intake [1]. The natural radioactivity elements are distributed everywhere in the environmental with different concentrations, their concentrations have been found to depend on the local geological condition and as such they vary from one place to another. It is necessary to monitor release of radioactivity into the environment in order to be able to provide an appropriate protection of humans [2].
