Abstract
Natural radioactivity has attracted a lot of attention in the world due to its crucial role in human safety. macaroni (Macaroni) is a dry, hollow pastry, made from cereals such as wheat, rice and barley. Macaroni is one of the basic and important for human beings, as well as its proven usefulness to the general health of human beings. Therefore, the measurement of natural radioactivity is a critical because of its direct impact on human safety. In this research, quantification has been made of natural radionuclide concentrations using NaI(Tl) gamma-ray spectrometry. The analyses of samples reveal the mean activity concentrations of 226Ra, 232Th, 40K% are found to 4.5E-01±0.071, 4.46±0.163 and 2.14±0.021, respectively. RLI,AUI,IC and Iα were also calculated the values were less than one also estimated annual gonadal equivalent dose (AGED) resulting with an average 302.98±07.59 mSv.y-1 where was higher than globally limits. Consumption of macaroni for adult was found (0.035±0.0015) mSv.y-1 which less than global studies , while the average value of cancer risk ( 1.21E-04±0.000005*10-3 mSv.y-1 Below the international permissible limits. The study can be considered as a basis for future studies on this basic substance in food.
