COMPARISON OF THE RADIATION SITUATION IN THE AGRICULTURAL AND OIL REGIONS OF THE ATYRAU REGION

Аннотация

The article is devoted to the comparison of radiation levels in the Issatay and Makhambet districts of
the Atyrau region. Atyrau region belongs to the regions of the oil-producing industry, which in turn can lead to
environmental pollution, including radiation. Therefore, a radiation analysis was carried out to measure the exposure
dose on the territory of the Isatai region, in which the oil-producing industry is developed, and for comparative
analysis, the same measurements were carried out in the Makhambet region, where there is no industrial activity and
the region belongs to an agricultural region. The studies carried out show that, according to the average values of the
exposure dose in both regions, it is in close values, which range from 9 to more than 14 mR/h in the industrial region
(Issatay region) and from 10 to 11 mR/h in the agricultural region (Makhambet region). In the Issatay district,
according to the average values, there is a slight increased content. The data on the exposure dose rate at the entrance
to the village and in the center of the village show that in the Makhambet district, the exposure dose data is higher in
the center of the village than at the entrance to the village, while in the Isatai district the indicators at the entrance to
the villages are, on the contrary, higher. In the Issatay region, within the villages, the data are similar to the
Makhambet region, and outside the settlements, there is a slight increase associated with the additional load from oil
pollution. The data on the level of measurement height show that at the level of the earth's surface and at the level of
50 cm, the values of the exposure dose are close in the values of the two regions, while there is a difference at the
level of 1 m. In the Issatay region, the exposure dose is higher than in the Makhambet region, this may be due to the
relatively greater accumulation of gaseous radioisotopes that accumulate as a result of evaporation from oil fields.
The background radiation in both regions does not exceed the maximum permissible dose and is not hazardous to
health.
