Hazel Park company tests tech for cleaning up radiation at Chernobyl site Shutterstock image Advertisement HAZEL PARK — Exlterra, a Swiss company with offices in Hazel Park that specializes in cutting-edge “green” technology, has unveiled a new invention it hopes will benefit the environment. Called the Nucleus Separation Passive System, or NSPS, the technology is currently being tested at a 1-hectare site in the Chernobyl exclusion zone. The purpose of the technology is to reduce radiation contamination in the area. For this experiment, Exlterra has partnered with SSE Ecocentre, a Ukrainian state-owned operation in charge of environmental monitoring at Chernobyl. The details of the experiment were announced in late April, on the 35th commemoration of one of the worst environmental disasters in history. In 1986, the Chernobyl nuclear power plant in Ukraine suffered two massive explosions when a routine test went horribly wrong. The roof was blown off, and the amount of radiation released was 400 times more than the atomic bomb dropped on Hiroshima.
