Cows in Fukushima radiation zone graze with new purpose
In an abandoned Japanese village, cows grazing in lush green plains begin to gather when they hear the familiar rumble of the ranch owner’s mini-pickup. This isn’t feeding time, though.
Instead, the animals are about to be measured for how they’ re affected by living in radiation—radioactivity that is 15 times the safe benchmark. For these cows’ pasture sits near Fukushima, a name now synonymouswith nuclear disaster.
The area was once a haven for agriculture with more than 3,500 cattle and other livestock. Ranchers who refused a government order to kill their cows continue to feed and tend about 200 of them. The herds won’t be used as food; now science is their mission.
Researchers visit every three months to test livestock living within a 20-kilometer radius of the Fukushima plant, where three reactors had core meltdowns after the facility was swamped by a tsunamiin 2011. It is the first-ever study of the impact on large mammals of extended exposure to low-level radiation.
The ranchers are breeders, as opposed to those raising cattle to sell for beef, and tend to be attached to their animals. They treat them almost as if they were children, even giving them names. The research gives them a reason to keep their beloved cows alive, and to hope that someday

ranching might safely return here.
Under a drizzling rain, doctors and volunteers wearing blue Tyvek protective suits draw the cows into a handmade pen of aluminum pipes. Five to six cows line up in the cage and are tied with a rope around their head and through their nose ring for solid support, so they won’t be hurt when the needle draws blood from their neck.
A ghost town
The gentle beasts moo from discomfort. The doctors work swiftly, drawing blood, collecting urine and checking for lumps or swollen lymph nodes. The checkup takes five minutes or less per cow.
Namie, 11 kilometers northwest of the plant, is a ghost town with no prospect of being habitable for years. But 57-year-old Fumikazu Watanabe comes every day to a ranch to feed 30 to 40 cows owned by seven farmers.
“What is the meaning of slaughtering the cows?” Watanabe said at a worn-out barn where healthy cows used to spend the night tending to their calves. The bones of animals that have died litter the ground outside.
“Keeping the cows alive for research purposes means that we can pass on the study to our next generation instead of simply leaving a negative legacy,” he said.
The research team, made up of veterinary and radiation experts from Iwate University, Tokai University and Kitasato University, was established a year after the meltdowns. They formed a nonprofit group called the Society for Animal Refugee and Environment Post Nuclear Disaster. Members volunteer to take the blood and urine samples and test them.
In 2012, the Japanese government ordered all livestock in the restricted area killed for fear that the breeding cows would continue to reproduce, and that cows exposed to radiation would have no sale value.
Keiji Okada, associate professor of veterinary medicine and agriculture at Iwate University, disagreed. He said the data will help researchers learn whether farmers can eventually work in affected zones.
“There are no precedent studies of animals being exposed to low-dose radiation, and we have no idea what results we are going to get,” he said. “That is exactly why it needs to be monitored .”
