Wild monkeys are soon going to be used to track radiation levels around the Fukushima Dai-ichi nuclear disaster site in Japan according to reports.

Researchers apparently plan to attach collars with GPS transmitters and Geiger counters to around 1,000 monkeys roaming the forests around Fukushima.

A huge earthquake and subsequent tsunami caused a triple meltdown at the Fukushima power plant in March 2011, releasing radioactive material into the atmosphere.

Fukushima University professor Takayuki Takahashi told news outlets the monkeys could help researchers get more accurate readings in areas that aren’t so accessible because 70% of the region is covered by forests.
