“…Wheat flour, the "Staff of Life", has been an essential commodity to human existence through the centuries and is currently the most widely consumed staple food. Moreover, numerous studies were conducted worldwide to investigate natural radionuclides in food consumed in different parts of the world (Hosseini et al 2006;Jibiri & Okusanya 2008;Ababneh et al 2009;Desimoni et al 2009). For a systematic treatment, a methodical approach is undertaken that focuses on a wheat flour type of food per study.…”

In this research, Uranium ( 238 U), Thorium ( 232 Th) and Potassium ( 40 K) specific activity in (Bq/kg) were measured in (12) different types of wheat flours that are available in Iraqi markets. The gamma spectrometry method with a NaI(Tl) detector has been used for radiometric measurements. Also in this study we have calculated the radiation hazard indices (radium equivalent activity and internal hazard index) and Ingestion effective dose in all samples. It is found that the specific activity in wheat flour samples were varied from (1.086 ± 0.0866) Bq/kg to (12.532 ± 2.026) Bq/kg, for

“…In this study, the average value of 40 K in beef is lower than the values reported in Korea by Choi et al (2008), in Nigeria by Akinloye et al (1999) and in Italy by Meli et al (2013), while our obtained value is higher than the value reported by Harb et al (2010) in Egypt 14,28,30,31 . Similarly, 40 K concentrations in milk were higher than concentration in milk from other countries 13,14,28,32,33 . Table 5 reveals some differences in activity concentrations in animal products compared to the countries reported.…”

Gülçin Bilgici cengiz in this research, the activity concentrations of 40 K, 232 th and 226 Ra in 41 grass samples collected from Kars region, turkey, were determined using gamma ray spectrometry. natural radioactivity concentrations in animal food products were calculated based on activity concentrations of these radionuclides in pasture-grass samples and dry-grass consumption of animals. the average annual effective dose from these radionuclides for local consumers due to indirect ingestion of cow milk, sheep milk, poultry, mutton and beef consumption have been calculated as 9.01, 0.24, 1.76, 0.38 and 5.25 µSv y-1 , respectively. Furthermore, the calculated average annual effective dose values for adults are within the values found in other countries worldwide. these results show that animal products can be safe for human consumption in terms of radiation exposure due to the natural radionuclides studied. Materials and Methods Sample collection and preparation. Since pasture plants are rich in protein, minerals and vitamins, they can meet the nutritional needs of all grass-eating animals. Pasture plants can be given as fresh, dry and silage to animals and can be grown for grazing 15. Grazing of various animal species in the pastures is the most economical and correct way 16. If the pastures are not used according to a certain system, they will deteriorate immediately. In order not to deteriorate the pasture structure and get the maximum yield from the pasture, it is necessary to graze

“…Wheat flour has been a fundamental staple to human presence across the centuries and is currently the more broadly expendable staple food. Additionally, several studies have been performed worldwide to inquire the natural radionuclides in food consumer in various areas of the world (6)(7)(8)(9). By spectroscopic analysis, the concentration of natural radionuclides ( 40 K, 232 Th, 226 Ra) is computed in diverse foods for human depreciation in the Abyan Delta in Yemen and it was found that the modified concentrations of radionuclides of 226 Ra, 232 Th, and 40 K in the selected specimens were 1.11 ± 0.08 , 1.00 ± 0.05 and 108.86 ± 3.49 , respectively.…”

In the present work, Uranium (238 U), Thorium (232 Th) and Potassium (40 K) specific activity concentration in (Bq/kg) was measured in five different types for wheat flours that are available in the Iraqi markets. The gamma spectrometry method with an NaI (Tl) detector has been used for radiometric measurements. Calculations of radium equivalent activity, annual effective dose equivalent, external hazard index (H ex), internal hazard index (H in), representing gamma index and gamma dose rate in all flour samples were 17.98132 Bq/kg, 0.0100334, 0.04502, 0.04857, 0.06872, 0.125883 and 8.181244 respectively. It is found that the average of specific activity concentration of wheat flour samples for 238 U, 232 Th and 40 K are 7.4564 Bq / kg, 6.27962 Bq / kg and 20.0658 Bq / kg respectively. This study proves that the natural radioactivity and radiation hazard indices were lower than the safe.
