Abstract

Radio-ecological researches, i.e. studies about the radioactivity on the Absheron peninsula were launched since 1930-1932, initially based on samples taken from the soil, water, and underground water. It was determined that the main cause of the radioactive pollution in the area is not limited to the effects of radioactive isotopes of natural origin rather it takes place also due to the contamination of oilfields driven by technogenic processes and the contact of water solutions of different mineralization with rocks and oilfields. However, complete exploration of the area in those times was not possible because of lack of modern equipment and devices and new technologies. It should be noted that despite the critical ecological situation prevalent in the Absheron peninsula, no comprehensive studies have been conducted on the radiation level of the area and the diminishing of possible radiation risk among the population living and working in the nearby areas. In this paper, the regularities of distribution of the radiation background in the territory of Absheron peninsula were analyzed and the most dangerous areas in terms of dwelling and operating were identified with proposing necessary measures towards such areas. Moreover, the changing of the radioactive background in relationship with age and types of a soil was determined for the first time based on laboratory analysis of samples taken from the area and the fieldworks conducted. In the presented paper, the radiation background of the Absheron peninsula was studied, thus determining the areas with the average value of the radiation background at 8.5 mcR/h but also the areas where it equaled 400-600 mcR/h, that is, the dangerous levels for living and working.

根据放射性核素光谱分析评估辐射生态状况
自 1930-1932 年以来,对 Absheron 半岛进行了放射性生态研究,即放射性研究。研究结果表明,该地区放射性污染的主要原因并不局限于天然放射性同位素的影响,而是由于技术工艺造成的油田污染以及不同矿化度的水溶液与岩石和油田的接触。然而,由于缺乏现代设备和装置以及新技术,当时不可能对该地区进行全面勘探。应该指出的是,尽管 Absheron 半岛的生态状况十分严峻,但却没有对该地区的辐射水平以及降低在附近地区生活和工作的居民可能面临的辐射风险进行过全面研究。本文分析了 Absheron 半岛辐射本底分布的规律性,确定了居住和工作最危险的地区,并提出了针对这些地区的必要措施。此外,根据对从该地区采集的样本进行的实验室分析和开展的实地工作,首次确定了放射性本底的变化与土壤年龄和类型的关系。本文对 Absheron 半岛的辐射本底进行了研究,从而确定了辐射本底平均值为 8.5 mcR/h 的地区,以及辐射本底等于 400-600 mcR/h 的地区,即对生活和工作有危险的地区。
