“…The researchers concluded that the levels of these radionuclides in the grains were generally low and did not pose a signi cant health risk and the values in (mBq/kg) were as follows: 66, 1.5, 19, 5500, 1100 for 239+240 Pu, 238 Pu, 241 Am, 137 Cs, and 90 Sr, respectively. Chen et al (1995) determined the radioisotope levels consisting of grains and oil seeds and about 1,098 samples of Oats. The grains and seeds samples were burnt and converted to ash and the gamma emitters 137 Cs and 40 K concentrations were determined using a HPGE well detector.…”

The aim of this study is to measure the natural radioactivity of potassium-40, uranium-238 and thorium-232 in rolled oat brands that widely consumed in Iraq. Based on these results, the radiological hazard parameters were evaluated. Five types of oat brands retailed Baghdad markets were tested. High purity germanium detector (HPGE) was used for the radiometric analysis. The mean activity concentration values of 238U, 232Th and 40K ranged from 6.88–10.61, 3.92–6.68 and 210.44–484.2 Bq/kg, respectively. The annual effective dose was the highest for a Ukrainian brand with 36.02 µSv/yr, while the radium equivalent activity values range from 31.43–56.1 Bq/kg. The results show that, regular consumption of these kinds of oats is radiologically safe for human health.

Oat is a nutritious healthy type of food that is widely consumed by various athletes and diet food in Iraq. This study aims to measure the natural radioactivity of potassium-40, Radium-226, and Radium-228 in rolled oat brands that are widely consumed in Iraq. Five types of oat brands retailed in Baghdad markets were collected and analyzed. A high-purity germanium detector was used for the gamma spectroscopy analysis. The mean activity concentration values of 226Ra, 228Ra, and 40K ranged from 6.9–10.6, 3.9–6.7, to 210–484 Bq/kg, respectively. The annual effective dose was the highest for a Ukrainian brand with 36.02 μSv/year, while the radium equivalent activity values range from 31.43 to 56.1 Bq/kg. The results of the study have been compared to a number of studies and showed good agreement. The findings of the paper show that regular consumption of these kinds of oats is radiologically safe for human health.
