Fukushima University researchers plan to measure forest radiation levels in Fukushima Prefecture by placing special monitoring collars on wild monkeys, in light of the nuclear crisis.

Each of the collars contains a small radiation meter and a Global Positioning System transmitter, and can be unclipped by remote control. This will allow a team led by robotics professor Takayuki Takahashi to recover the collars and collect the data within one to two months after the monkeys are released back into the wild, they said.
