The concentrations of Natural Radioactivity in Pergamum Harmala Seeds

ABSTRACT The concentrations of naturallyradioactive occurring and technically enhanced radioisotopes of 10 samples of Peganumharmala insecular equilibrium, collected from different markets in province of Baghdad, have been investigated; using HPGegamma-ray spectroscopy established at low background configuration. Also, the activity concentrations of 40K (1460.81 keV ), 75Se (96.73keV ), 85Kr (513.99 keV), 88Y (1836.01 keV) and 134Cs (563.23 keV, 801.93 keV and 1167.94 keV ) are determined. The average Activity concentrations of the radio elements 40K,75Se, 85Kr and 134Cs in Peganumharmala samples are found to be 425±12.22, 350±10.05, 304±8.73 and 159.17±4.57 Bq/kg respectively, which are below the international global limits. Apparently, the traces of different medium and heavy elements have been investigated using the X-ray fluorescence spectrometer analysis. The measures show the dominant of Potassium-K element in PM samples with the average concentration obtained 53652.62ppm. The other measured traces of the elements indicate a decreasing in the order of K>Fe>Ti>Zr>Nb>Sr>Y>Zn>Ga for the PM samples rather than the order mentioned in reference [37].
