Found that none of the berries or in trees radiation does not accumulate dirt . Nevertheless , began rehabilitation work in contaminated areas. Acted dvadtsatisantimetrovy layer of earth mounds and exported in special areas in each of the three areas for radioactive waste disposal . In the region there are currently three burial capacity from 60 to 200 cubic meters. Has a number of large public research center RIAR . In 1992 was held gamma — spectrometric survey areas of Ulyanovsk and Dimitrovgrad. It is costly to local environmentalists managed to carry through the state budget. Viewed the land within 30 kilometers of these cities. The helicopter ride was installed special equipment , which recorded the places of strong radiation contamination . After shooting all the sources of increased radiation in the cities studied . In Ulyanovsk record for pollution became Instrument Plant in whose territory found 167 radioactive sources. Blame was slag. Once the plant was brought radioactive coal and control in the enterprise was not. Coal is burned , and the slag used in the territory , some portion sold . Subsequently, all the radioactive slag removed from the plant . Ground leveled , and the place built hundreds of garages. Still a big problem for Ulyanovsk — garages that are on radioactive soil. In addition, there is no » capacity » for such large amounts of contaminated soil . Small spot of unknown origin was found between average and Old Algashami . It is known that there ravine phosphorite and oil shale outcrop . But where radiation is not clear. Dimitrovgrad one of the most radioactive sites was Borstal .
