چکیده
|
The activity concentration of 226ra, 232th, 40k and 137cs in soil, plant and some waste samples at the industrial facilities in helwan city in egypt were measured using γ-ray spectrometry to estimate the radiation hazard as well as establishing a database for radioactivity levels in helwan city. also the inductively coupled plasma-mass spectrometry (icp-ms) technique was used to determine concentration of al, ba, co, cr, cu, fe, mn, ni, pb and zn in samples. the activity concentrations of 226ra, 232th, 40k and 137cs were found to be 30.6 (8.5-238.2), 12.6 (6.3-37.3), 175.8 (66-327.8) and 1.1 (0.2-3.0) bq/kg for soil; 8.6 (2.1-26.2), 7.9 (3.7-14.3), 1070.3 (296.4-2083.5) and 2.30 (0.8-3.07) bq/kg for plant and 1853.7 (116.0-5019.0), 633.8 (51.0-1503.0), 132.5 (50.0-204.0) and 3.7 (2.0-8.0) bq/kg for waste samples, respectively. the concentrations of these radionuclides were compared with the typical world values. radium equivalent (raeq), representative level index (iγr), dose rate and annual effective dose were estimated
