Although it's impossible to say for sure what consequences an accident at a nuclear power plant might have on human health in the environment nearby, experts can make some predictions.

On February 24, the first day of Russia's war in Ukraine, Moscow's troops took over Chernobyl, the scene of the world's worst ever nuclear accident. Following a 35-day occupation, Ukraine regained control of the defunct plant but workers have had a hard time returning it to regular functioning. Employees were forced to rebuild IT systems from scratch after specialist equipment and software was ransacked by Russian soldiers. Chernobyl remains a highly volatile site, with hundreds of tonnes of radioactive material still sitting under a protective cover.

This week, we start with some good news. Radiation levels are "quite normal" around Chernobyl. The head of the UN's nuclear watchdog confirms that Russian forces have pulled back from the site of Europe's worst-ever nuclear disaster. The IAEA is working with both sides to avoid Chernobyl again becoming a frontline in the war in Ukraine.

Down an overgrown country road, three startled wild horses with rugged coats and rigid manes dart into the flourishing overgrowth of their unlikely nature reserve: the Chernobyl exclusion zone.

Boston Dynamics robotic dog known as 'Spot' designed to detect radiation, was spotted working at Chernobyl’s nuclear reactor number four, as the State Agency of Ukraine on Exclusion Zone Management reported on October 23.

Firefighters worked for 10 days to extinguish fires that broke out in the forest around the Chernobyl nuclear plant. Ukrainian officials say they've tracked down two men who are believed to be behind the blazes.
