The health department in Kashiwa, a city in Chiba Prefecture with multiple radiation hot spots, has received numerous inquiries from worried residents wanting to find out their internal radiation levels.

Kashiwa official Seiichi So meya says he understands their concerns, especially when it involves parents with small children, but he still has to ask them to wait.

"We want to (conduct radiation checks) and are holding discussions with a radiation research institute, but there is no concrete plan yet," he said.
