Abstract:

The results of geochemical assessment within Tomsk-city according to the dust-aerosols study are presented. The snow samples were collected to study of dust atmospheric fall-outs. Instrumental neutron activation analysis was used when studying geochemical composition of snow solid residue. According to the received data, places of anomalous values of daily dust fall-outs, containing rare, rare-earth and radioactive element were revealed. These places were revealed in the north-east of the city, where most part of plants of the construction industry are located, and in central part of the city, where the largest electric power station is located.
