“…Under natural environmental conditions, 137 Cs and 90 Sr mainly enter the human body through the food chain and respiration. Both 90 Sr and 137 Cs have long biological half-lives in the human body 3 – 8 , therefore it is important to continuously monitor 90 Sr and 137 Cs in environmental and food samples, especially those from the surroundings of nuclear facilities, to ensure the radiological safety of individuals and the environment. In contrast to 137 Cs, long-term monitoring data for 90 Sr activity in environmental and food samples worldwide are sparse.…”

Environmental radioactivity monitoring in the surroundings of nuclear facilities is important to provide baseline data for effective detection in case of any radioactive release in the region. In this work, we report for the first time the long-term monitoring data of 137Cs and 90Sr in environmental and food samples around Qinshan nuclear power plant in 2012–2019. The distribution levels, temporal variations and source terms of 137Cs and 90Sr in the investigated samples were discussed. The annual effective dose (AED) for the local population from the ingestion of foods was also evaluated. Peak values of 90Sr and 137Cs concentrations and 137Cs/90Sr activity ratio were observed in total atmospheric deposition in 2016 and some water and food samples in the following years. This seems to be associated to an additional radioactive input, mostly likely from the operational release of a local facility. This demonstrates that 90Sr and 137Cs, especially the 137Cs/90Sr activity ratio, are sensitive indicators for detecting potential radioactive releases. Nevertheless, overall 90Sr and 137Cs activity concentrations measured during 2012–2019 in this work were at the background levels with average AED far below the internationally permissible limit and recommendation.

Radioactivity in Food may be contaminated with radioactive materials due to the natural and a nuclear emergency. The vegetables and fruits will become radioactive by deposit of radioactive materials falling on that from the air or through rain water. The aims of the present work were to measure the specific activity and annual effective dose as a result of the intake of vegetables and fruits collected from local market in Najaf governorate. Natural radioactivity was measured in samples using gamma ray spectrometer in this study. The results show that the average specific activities in vegetables samples for 238 -1 , while the total average annual effective dose in vegetables samples for adults, children (10 years old) and infants is estimated to be 0.117, 0.122, and 0.179 mSv, respectively, while the total average annual effective dose in fruit samples for adults, children (10 years old) and infants is estimated to be 0.141, 0.295, and 0.388 mSv, respectively. The values found for specific activity and the annual effective dose in all samples in this study were lower than worldwide median values for all groups according to UNSCEAR (2000) and ICRP (1996) respectively; therefore, these values are found to be safe.Keywords: Natural Radioactivity. Vegetables and Fruits. Gamma ray spectrometer. Iraq food RESUMOA radioatividade em alimentos pode acontecer por meio de materiais radioativos, graças a ocorrências naturais e/ou nucleares. Legumes e frutas tornam-se radioativos por depósito de materiais radioativos que caem a partir do ar ou através da água da chuva. Os objetivos da presente pesquisa foram: medir a atividade específica e dose efetiva anual, como consequência da ingestão de frutas e legumes coletados de um mercado local na província de Najaf, Iraque. Neste estudo, a radioatividade natural foi medida em amostras utilizando espectrômetro de raios gama. Os resultados mostram que as atividades específicas médias em amostras vegetais para 238 U, 232 Th e 40 K foram 5,21, 4,76 e 186,15 Bq kg -1 e as atividades específicas médias para 232 Th, 40 K em amostras de frutas foram 2,53, 211,64 Bq kg -1 , enquanto que a dose média anual eficaz total em amostras de vegetais para adultos, crianças (10 anos) e recém-nascidos é estimada como sendo 0,117, 0,122, e 0,179 mSv, ao passo que a dose média anual eficaz total em amostras de frutas para adultos, crianças (10 anos) e recém-nascidos é estimada como sendo 0,141, 0,295, e 0,388 mSv, respectivamente. Os valores encontrados para essa atividade específica e a dose efetiva anual em todas as amostras neste estudo foram inferiores aos valores médios mundiais para todos os grupos de acordo com UNSCEAR (2000) e ICRP (1996), respectivamente; portanto, concluiuse que tais valores são considerados seguros.Palavras-chave: Radioatividade natural.

This paper investigates the activity concentration of radionuclides (226Ra, 232Th, 40K and 137Cs) in the wheat grain samples using a high-purity germanium detector. Thirty-six wheat grain samples were collected from different locations of Koya City, Iraqi Kurdistan region. Average activity concentrations of 226Ra, 232Th and 40K in wheat grain are found to be 0.407 ± 0.097 Bq.kg-1 for 226Ra, 0.36 ± 0.14 Bq.kg-1 for 232Th and 109.25± 2.214 Bq.kg-1 for 40K, respectively. The measured activity concentrations for the radionuclides are compared with the reported data from other countries. In addition, the fallout radionuclide of 137Cs has no detection of in the wheat grain samples. The radium equivalent activity Raeq, internal and external hazard indices Hin and Hex, and annual gonadal dose equivalent are calculated for the measured samples. The total ingestion dose is 113.19 µSv.y-1, which is below the world average value of 290 µSv.y-1.
