Light Painting: Nuclear Radiation Testing in Bryansk Region in Russia

A special light painting tool displays radiation levels in real-time at the gates of a ruined church in Starye Bobovichi, Russia. Here white light shows contamination levels up to 0.23uSv/h, while orange highlights elevated levels – from 0.50uSv/h to 0.85uSv/h around the gates. 30 years after the 1986 Chernobyl nuclear disaster, the schoolyard still contains areas of elevated radiation levels.
