Fransson said routine checks at Forsmark later led to cooperation between various authorities in Sweden and the other Nordic countries. It was a major puzzle trying to sort out from where the radioactivity was coming. But later in the afternoon on that day Forsmark got a clean bill of health from Sweden's National Nuclear Inspectorate as wind-borne nuclear pollution from abroad was confirmed by reports from Nordic nuclear monitors. The disaster led to strict routines at the Forsmark nuclear station, Fransson said. We had to have shoe limits outside for months afterwards.
People put on shoe covers outside before going in.
Robinson, who today works at Uppsala University, says his life was changed through the events. The anniversary of Chernobyl around the world on Friday was marred by a new radiation incident at the plant on Thursday. Chernobyl spokesman Oleg Goloskokov blamed the incident on careless work practices and said contamination caused by a spillage of radioactive dust had been cleaned up overnight. There was no threat to the environment. The Forsmark plant, however, does not plan to commemorate the day.
