The radiation shield is designed to prevent further radioactive material leaking out over the next century. It measures 275m (900ft) wide and 108m (354ft) tall and cost $1.6bn (£1.3bn) to construct.

Previous research has shown how frogs inside the Chernobyl Exclusion Zone may have rapidly evolved melanism to survive the historically high levels of radiation in the region.

Love's research established that wolves in Chernobyl have altered immune systems, "similar to cancer patients undergoing radiation treatment." This is important — as scientific research reveals more ...

Chernobyl wolves are growing resistant to cancer despite their high radiation exposure. The wolves are exposed to six times the legal safety limit of radiation for humans.

Where to find the current radiation background To track the radiation background in Ukraine, a special online map was launched by the developers of the SaveEcoBot service. It started working last year ...

When a radiation cloud at a high altitude is exposed to rainfall, the radioactive fallout contaminates the downwind area below. Crops and livestock are acutely affected by this.

But “there’s no evidence of that.” Scientists have been trying to pin down how radiation exposure at Chernobyl has affected wildlife for decades (SN: 5/2/14).

One of the reactors blew up, releasing a cloud of radiation over Ukraine and across Europe. The Chernobyl disaster remains the worst civilian nuclear incident in history.
