A group of about 30 Kanagawa Prefecture residents, including mothers with young children, started a service Monday to measure radiation levels in food.

The group will use devices worth around ¥1.3 million each, purchased with donations, installed at each of its two offices in Yokohama and Sagamihara to check for such iodine, cesium and other radioactive substances.

"We'll do what we can on our own without simply relying on local governments," said Etsuko Shono, a member of the project.

The group will accept reservations on its website (www.ycrms.net) and food samples by mail. The results will be mailed back in about 10 days of the test. It costs ¥3,000 to ¥5,000 per sample.
