Basic Survey: Responses

During the survey period, i.e., the four months from March 12 to July 11, 2011, ambient dose rates were especially high and ascertaining people's external doses during this period is most important.

Approx. 566,773 people have made responses so far (response rate: 27. 6%).

Thanks to the introduction of the simplified inquiry sheet and assistance for filling in the inquiry sheet offered at venues of the Thyroid Examination, the response rate improved, mainly among young people.
