More and more people have been engaged in monitoring connected with numerous spheres of natural sciences. In Northern Tajikistan radiation monitoring is considered as mostly important, as due to intensive reclamation of radioactive ore deposits the pollution of biosphere with nuclides is quite possible. With the purpot we have been conducting permanent control of natural radioactivity of air, soil, water and food stuffs by portable and stationary apparatus for the last ten years.

Measurements comprise a vast territory: 11 districts, 156 populated settlements of the left bank of the Syr-Darya river, 50 kinds of food stuffs sold at the markets of Northern Tajikistan. All in all we have explored about 5000 units.

According to the results of the measurements we can say that the general radiation background of the Syr-Darya river basin in the range from Kanibadam to Bekabad dyke and up to the northern slopes of the Turkestan mountains in the boundaries of 60-120 kilometres zone constitutes 10-20 micro-Roentgens per hour and is in the limits of sanitarily admittable doze.
However, there are local places connected with the processing of uranium ore, with anomally high radiation reaching 600-800 micro-Roentgen's per hour. On evincing those heterogeneities we notify local authorities, the administration of enterprises and sanitary services for taking urgent measures aimed at the isolation of highly radioactive spots in order that radionuclides should not spread and get into the natural environment. Into the bargain we undertake arrangements of the enlightenment of people about the action of radiation through mass media.
