Glue and duct tape used to fit rat snakes with dosimeters and GPS movement trackers to help researchers understand long-term effects of radiation

Researchers have used snakes fitted with tracking devices and dosimeters to measure radiation levels in the area around the Fukushima Dai-ichi Nuclear Plant, which suffered triple meltdowns in March 2011.

The meltdowns in Japan caused by a giant tsunami released more radiation into the atmosphere than any nuclear disaster except Chernobyl in 1986.
