Radioecological Monitoring of Adjacent Territories to the Former Semipalatinsk Nuclear Test Site, East Kazakhstan

Abstract

This paper presents the results of complex radioecological monitoring of the territories, which are situated near the Semipalatinsk Nuclear Test Site, East Kazakhstan region. The radiometric measurements showed that the concentration of radon and beta particles are below the permissible levels. EROA values of a radon in rooms fluctuates from 44 Bq/m3 to 195 Bq/ m3. The measured values of fluency of betta-particles in all the studied points are less than 10 freq/ min*cm2. A specific activity of radionuclides, such as Am-241, Cs-137 and Pu – 239/240 in soils, plant, water, meat and milk were evaluated.

A Risk and Hazard Analysis Model for the Production Process of a New Meat Product Blended With Germinated Green Buckwheat and Food Safety Awareness

“…Irrespective of the outcomes described above, the likelihood that meat and meat products exceed the standards for these indicators (MACs) cannot be ignored. Since environmental pollution due to these heavy metals increases every year, and the East Kazakhstan region of the Republic of Kazakhstan was the nuclear testing region for around 42 years, this could lead to the presence of these contaminants in the meat industry eventually ( 46 ). The analysis of toxic substances in the meat and meat products revealed that the average concentration of heavy metals did not exceed the respective MACs.…”

The quality of beef in the conditions of the former Semipalatinsk Test Site

“…A detailed analysis of AA showed a decrease in the AA composition in all samples in comparison with the standards established by WHO/FAO. In the work of Duyssembaev et al (2016) a study of beef from four zones of the test site was also conducted, the following results were obtained: the amount of AA in beef from Sarzhal village (the extreme risk zone) was 87.3%; Akzhar village (the maximum risk zone) was 86.4%; Novopokrovka village (the increased radiation risk zone) was 86.4%; Karatau village (the minimum radiation risk zone) was 84.2%. Thus, this study did not reveal any dependence of the AA content level on the contaminated zone in which the animals were raised.…”

“…So, obtaining a safe and complete product is important for the region development (Ospanova, 2017). The territories of the former SNTS have all the conditions for growing high‐quality meat breeds of animals, this is facilitated by the traditions of selective breeding and animal husbandry, large areas of pastures (Duyssembaev et al, 2016). However, the biggest problem, even many decades after the test termination, remains the issue of radiation contamination and its impact on the quality of animal products that can be obtained under these conditions (Kukhtyn et al, 2020).…”

“…In the work of Anuarbekova et al (2011) found the features of structural differences in the cows muscles, as well as mineral composition, connected with radiation risk zones from which the samples were obtained. Duyssembaev et al (2016) cite the studies' results of the amino acid (AA) composition of beef from various risk zones. These researchers conclude that in extreme radiation risk zones, not only the structure, but also the composition, and with it the nutrition value of beef decreases.…”

Индикаторы Ядерного Техногенеза На Примере Территории, Прилегающей К Бывшему Семипалатинскому Испытательному Полигону

“…Так, проведен комплексный радиоэкологический мониторинг территорий, расположенных вблизи СИП, где объектами исследования являлись: поч ва, растения и продукты питания местного произ водства. В данных компонентах оценены удельные активности радионуклидов, таких как 241 Am, 137 Cs и 239/240 Pu [8,9]. Также оценены активности 137 Cs в почве, воде, растительности и коровьем молоке в 10 точках трех регионов (Абай, Аягуз и Урджар) которые расположены к юго востоку от СИП [10].…”
