TALLINN - A small increase in radiation levels has been observed in northeastern Europe, and the source thereof must be ascertained, Estonian Minister of Foreign Affairs Urmas Reinsalu said.
"Various states have reported a small increase in the concentration of radioactive isotopes in northeastern Europe," Reinsalu wrote in social media. "While the levels are harmless to human health, the increase is definitely man-made and the cause thereof must be determined as it is important in terms of our security and international security more broadly."
"In Estonia, radioactivity monitoring is carried out by the Environmental Board. Estonia is staying in touch with the International Atomic Energy Agency and other states with regard to this issue. This morning, I exchanged information with the foreign ministers of Finland and other Baltic states," Reinsalu said on Sunday.
