We spoke to a radiation expert in Kyiv about the current nuclear accident risk

Russian troops have been bringing death and destruction to Ukraine since they invaded on February 24. But there's a risk they could cause a nuclear accident too, according to Vadim Chumak, head of the external exposure dosimetry lab at Ukraine's National Research Center for Radiation Medicine in the country's capital, Kyiv.

Since Russia took control of two nuclear power plants inside Ukraine earlier this month, reactors inside those plants have been cut off from their power sources, and radiation-monitoring devices have been disconnected, leading to concerns of a potential nuclear disaster.

One particular worry is that if a nuclear catastrophe strikes, scientists might not be able to monitor it or measure its impacts, says Vadim Chumak, head of the external exposure dosimetry lab at Ukraine's National Research Center for Radiation Medicine, who played a key role in dose assessment following the Chernobyl disaster. Today, he remains close enough to Kyiv to help should a nuclear disaster result from Russia's invasion.

From a house in Ukraine's countryside, just outside the capital, Chumak spoke to MIT Technology Review about his hopes and fears, the risks of radiation leaks from hospitals, and the fact that much of the country's radiation monitoring equipment is obsolete. Read the full interview.
