This paper summaries the reports on early internal exposure to the public due to the accident of TEPCO Fukushima Daiichi Nuclear Power Station in March 2011 and the issues on the internal dose assessments. The results by whole-body-counter (WBC) measurement for early internal exposure showed that the committed effective doses to most of the residents were less than 1 mSv. Thyroid equivalent doses were much smaller than the mean thyroid dose in the Chernobyl accident. Through the internal exposure measurements made so far, there are the issues such as lack of the data associated with the internal dose assessments, radioactivity measurement by the WBC, selection of intake scenarios, and internal dose assessments for insoluble and radiocesium-bearing radioactive particles with a high activity.
