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.

Highlights

The Semipalatinsk Nuclear Test Site (SNTS) left a huge mark in the history of a nuclear race of the period of Cold War
Settlements of the Abaysky, Beskaragaysky and abolished Zhanasemey areas, Akbulak, Abralin, Algabas, Aynabulak, Karaolen and Tanat rural districts of the city of Semey of the East Kazakhstan region, Akzhar and Maldar rural districts of the May region of the Pavlodar region belong to a zone of the maximal radiation risk
Settlements of Borodulikha, Zharma, Ayaguz, Glubokoye, Shemonaikha, Ulan districts, the cities of Semey, Kurchatov, UstKamenogorsk and Ridder of the East Kazakhstan region belong to this zone; Karkaralin district of the Karaganda region within the territory of the abolished Kazybek bi district, the May region of the Pavlodar region

Summary

Introduction

The Semipalatinsk Nuclear Test Site (SNTS) left a huge mark in the history of a nuclear race of the period of Cold War. 2) A zone of the maximal radiation risk - a part of the territory, which underwent radiation pollution with a dose of impact on the population from 35 to 100 rem for the entire period of tests. 3) A zone of the increased radiation risk – a part of the territory, which underwent radiation pollution with a dose of impact on the population from 7 to 35 rem for the entire period of tests. Many scientists and residents of settlements, adjacent to SENTS, consider hasty return of lands to national use, in connection with danger of migration of dangerous radionuclides in a biological line-up of a surrounding medium In this regard, there is a need of carrying out monitoring of SENTS and identification of radiation-hazardous places [5,6]. There are sites where radioactive waste placed [7]
