title: [Radiation measurement and dose assessment].
abstract: In order to assess an effective dose, it is necessary to evaluate the external exposure caused by gamma ray or neutron, and the internal exposure caused by ingestion from contaminated food or soil and inhalation from radioactive fallout. It is also necessary to consider the equivalent dose of the skin in case of the existence of a high density surface contamination by beta emitters. An early evaluation on the effective dose should be indispensable by a dose calculation using easy expression and by a suitable radiation measurement for the radiation emergency. The accuracy of the effective dose may not be significant at the first stage, but the true value should be included in the range of the fluctuation. Here, radiation measurement is the most effective means to be able to avoid the misjudgment.
