As a result of these actions the contamination levels of the surfaces have been reduced from 10⁶ to 2000-8000 β-part/(cm².min) and gamma radiation levels dropped from 10-600 mR/h to 2-10 mR/h. As a result of the power plant site decontamination the overall gamma level around the first unit was reduced to 20-30 mR/h. The actions taken for the decontamination of the 30 km zone and the prospects for its return to economic activity are also presented
