The concept of population dose is of importance and of interest at the point of radiation protection of puplic. We devided it into two categories, source-related population dose and individual-related population dose, and estimated each population dose of Japan. We surveyed all sources that caused exposure to Japanese population. A number of sources, both naturally-occuring and man-made, contributed to population exposure. According to source-related dose assessment, average annual effective dose equivalent was about 3.3mSv, and about half of which, i. e. 1.6mSv, was given from medical exposure. And from the results of individual-related dose assessment we proposed the allocation of the annual dose limit of public for each controllable source, that is, 2.5mSv/yr to nuclear faculties, 1.0mSv/yr to miscellaneous sources, 1.5mSv/yr to probablistic exposure.
