Wild monkeys to help gauge Fukushima radiation
FUKUSHIMA–Wild Japanese monkeys wearing special collars fitted with dosimeters and Global Positioning System devices will be used to measure radiation levels in the mountain forests of Fukushima Prefecture in an experiment due to start this month.
A group of researchers at Fukushima University plans to start the experiment to determine the dispersal of radiation due to the crisis at the Fukushima No. 1 nuclear power plant and support decontamination work.
Led by Prof. Takayuki Takahashi, who is also the university’s vice president, the group will attach the collars to monkeys as early as this month.
Radiation levels on mountains are currently measured by plane from the air, but using monkeys should make it possible to measure levels deep in mountainous areas that planes struggle to cover.
