Impact of the Former Salaspils Nuclear Reactor on the Surrounding Territory

The paper presents results of the long-term environment radioactivity monitoring in the vicinity of the decommissioned Salaspils Nuclear Reactor. Data include Cs-137 contamination levels of soils, H-3 concentration in ground waters, as well as gross beta activity of sewage and rainwater drainage of SNR. Special attention is devoted to the radioactive pollution of water due to leakage from the special wastewater basin detected in December 2014.
