Estimation of the radiation hazard indices in most types of Pasta spread in the Iraqi markets

Abstract

Abstract pasta (Macaroni) is a dry, hollow pastry, made from cereals such as wheat, rice, barley, etc. It is a diet rich in carbohydrates for different age groups. In this research study examines the emergence one of the long-lived gamma radiation emitters in the various types of pasta available in the Iraqi market. We found concentration of (238U), (232Th) and (40K) In units (Becquerel / kg) measured in (20) Various types for pasta that could be obtained in the Iraqi market.( Radium equivalent ), (internal hazard index), and (absorbed dose rate) were also calculated for all studied samples. radiometric measurements by using the gamma spectrometry NaI(Tl) detector. The specific activity in Macaroni samples were wide-ranging from (0.232±0.195) Becquerel / kg to (22.869±2.005) Becquerel / kg and at a rate (6.081) Becquerel / kg for238U, For 232Th From (0.018±0.36) Becquerel / kg to (114.269±1.40) Becquerel / kg and at a rate (21.672) Becquerel / kg and for 40K from (58.724±2.28) Bq/kg to (1145.99±10.57) Becquerel / kg and at a rate (663.092) Becquerel / kg. Also, Where we found that the internal risk index as well as the radium equivalent in the samples (pasta) ranged from (0.0135) to (0.8031) Becquerel / kg and at a rate (0.2672) Becquerel / kg and for the equivalent radium, the values were from (4.780) Becquerel / kg to (274,515) Becquerel / kg, and at a rate (177.262) Becquerel / kg. This study showed that, risk indicators calculated in this study are safe and do not constitute any health threat to humans.
