Wild monkeys and boars enlisted to help measure Fukushima radiation in Japan

Many challenges remain in measuring radiation leaked from the Fukushima Daiichi nuclear plant in Japan, after a devastating quake and tsunami 9 months ago left that site crippled. The crowdsourced efforts of a DIY tech group called Safecast were the subject of a report I produced with Miles O'Brien for NewsHour; other projects to capture this badly-needed data have been led by young mothers.

Today, a story is circulating about a group of researchers from Japan's Fukushima University who plan to enlist the help of wild monkeys, and maybe wild boars, to monitor radiation starting in Spring of 2012.

From the Wall Street Journal:

Researchers from Fukushima University plan to kit wild monkeys out with radiation-measuring collars to track the contamination levels deep in the forests, where it’s difficult for humans to go. (...) The monkey collars are geared with a small radiation-measuring device, a GPS system and an instrument that can detect the monkey’s distance from the ground as the radiation level is being tallied. Mr. Takahashi said more contraptions may be added, but these will be the three main ones.

So, it sounds like they'll capture the critters, tranquilize them, attach the devices, then free them again back in the wild to roam around and passively gather/transmit readings.

CNN reports that veterinarian Toshio Mizoguchi of the Fukushima Wildlife Rehabilitation Center (run by the regional government) came up with the idea. He wanted to find a way to observe the effect of radiation on the wild animals near Fukushima.

The researchers will first focus on the mountains near Minamisoma city, about 25 kilometers/16 miles from the Fukushima Daiichi plant. Some 14 monkey colonies are known to inhabit this area. Minamisoma city and its mayor Katsunobo Sakurai became "internet-famous" when the mayor posted a desperate appeal for help on YouTube.

During our reporting trip to Japan, I went with Miles to interview mayor Sakurai, by the way -- the interview didn't make it into our NewsHour piece, but man, he was really a fascinating character. Apparently things have not been easy for him personally or politically since.

  1. Originally they planned to put these devices on the various wild Godzillas now roaming the area but this has proved to be very impractical so they settled on wild monkeys and wild boars instead.

  2. Those monkeys look relaxed now, but wait until they find out they’ve been taking a hot soak in one of the reactor’s cooling pools.

  3. I hope the data collected can be put to good use, but it is sad to see animals come to harm. Today is Monkey Day, too… [www.monkeyday.com]

  4. I had an image of monkeys in lab coats with Geiger counters. 

    The reality is less cute, but I suppose necessary.

  5. Apropos of nothing in particular, I was just thinking about those snow monkeys the other day and how one never seems to see them photographed in any place OTHER than those thermal baths. Surely they must have other places to hang out?
