Conclusion

The direct monitoring or measurement of personal radiation doses was not carried out sufficiently, especially for internal dose estimation at the early period after the accident, compared with monitoring of radiation dose rates and radioactivity in the environment. The huge numbers of becquerels (Bq) in the environment (kilo, mega, giga) caused severe concern initially, although if these numbers were converted to effective doses, the actual personal radiation doses are not so significant. I wish to conclude this chapter by stressing that it is important in the future to clarify the personal radiation dose soon after an accident so that suitable and effective protective measures can be undertaken for residents against radiation risks to ensure their safety.
