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.

“…Drinking water can be affected by man-made radiation caesium-137 ( 137 Cs) which made through nuclear accidents and processes is an example of anthropogenic radionuclides [10]. The average of doses to many of organs of the human body also represent a significant way for long-term health conditions [11]. Most of people are subjected to these sorts of radiation sources every day and in anywhere.…”

An investigation was carried out on several radiological hazard indices in twenty three bottled drinking water samples that were collected from various locations in Basrah/Iraq. The specific activity of 238U, 232Th, 40K and 137Cs isotopes was measured using the surveillance and measurement (SAM) device, model 940-2G. The specific activity values of U-238, Th-232, K-40 and Cs-137 ranged as (0.029±0.001-3.017±0.003) Bq/l, (0.025±0.002-2.326±0.001) Bq/l, (4.706±0.002-161.560±0.001) Bq/l and (0.040±0.003-0.953±0.001) Bq/l, respectively. The calculation of many risk indices have been carried out for all drinking water samples. All results have agreed with those reported in published studies and all these obtained findings have been recognized to be below the worldwide limit values. Therefore, there is no significant radiological risk in drinking bottled water brands in Basrah governorate, Iraq.

“…In addition, 137 Cs is the most important fission product released to the environment as a result of nuclear activities, because this radionuclide rapidly passes through soil to vegetables and creates a dose effect (Hammood and Khalifa, 2011. p. 22). Several studies have been measured and evaluated values for the level of natural radioactivity in worldwide national studies; such as, in Malaysia (Alzubaidi et al, 2016;Salih, 2018), India (Sureshgandhi et al, 2014;Punniyakotti and Ponnusamy, 2017), Nigeria (Fasae, 2013: Jibiri andBiere, 2014), Brazil (Veiga et al, 2006), Egypt (Darwish et al, 2015), and Saudi Arabia (El-Taher and Abdelhalim, 2013: Al-Zahrani, 2012).…”

In this work, the activity concentrations of natural radionuclides 226Ra, 232Th and 40K in soil samples from Erbil governorate, Iraqi Kurdistan were investigated by a gamma-spectroscopy system based on high-purity germanium (HPGe) detector. This is to assess the dose of radionuclides exposure to the population, knowing the health risks and to have a baseline for future changes in the environmental radioactivity. It was found that the activity concentrations of 226Ra, 232Th and 40K were ranged from (14.6 ± 1.6 to 38.2 ± 2.8 Bq.kg-1), (4.5 ± 1.4 to 52.4 ± 5.8 Bq.kg-1) and ( 302.8 ± 12.6 to 388.6 ± 12.8 Bq.kg-1), respectively. The measured activity concentrations for these radionuclides were compared with the reported data of other countries and with the worldwide average activity of soil. Radium equivalent activities, absorbed dose rate, excess lifetime cancer risk and the values of hazard indices were calculated for the measured samples to assess the radiation hazard of the natural radioactivity in all samples to the people. It was concluded that the radium equivalent activities of the studied samples are below the internationally accepted values. These results show that annual effective dose absorbed via occupant from activity construction of soil samples used in the under place is below 1.0 mSv.y-1. It is concluded that the assessment radioactivity of soil are within acceptable levels and does not pose any health hazard to the population.
