The government’s failure to act quickly, a growing chorus of scientists say, may be exposing many more people than originally believed to potentially harmful radiation. It is also part of a pattern: Japan’s leaders have continually insisted that the fallout from Fukushima will not spread far, or pose a health threat to residents, or contaminate the food chain. And officials have repeatedly been proved wrong by independent experts and citizens’ groups that conduct testing on their own.
“Radioactive substances are entering people’s bodies from the air, from the food. It’s everywhere,” said Kiyoshi Toda, a radiation expert at Nagasaki University’s faculty of environmental studies and a medical doctor. “But the government doesn’t even try to inform the public how much radiation they’re exposed to.”
But not everyone was convinced. Some Tokyo residents bought dosimeters. The Tokyo citizens’ group, the Radiation Defense Project, which grew out of a Facebook discussion page, decided to be more proactive. In consultation with the Yokohama-based Isotope Research Institute, members collected soil samples from near their own homes and submitted them for testing.
