Dogs carrying radiation detectors the size of a mobile phone have been dispatched to Ukraine to provide troops with early warning of a nuclear disaster.
Real-time data on radiation levels collected by eight dogs will be sent to soldiers on the ground, who will be able to decide whether to move forward into battle.
The radar technology, made in NETPark, Sedgefield, County Durham, is so sensitive that it will pick up even the lowest levels of radiation. It can also identify the exact nature of the radioactive source material, such as plutonium or uranium.
