METHODS FOR ESTIMATION OF INTERNAL DOSE OF THE PUBLIC FROM DIETARY

Following the issue of its Publication 26, ICRP has successively published itsPublication 30 to meet the great changes and improvements made in the BasicRecommendations since July of 1979. In Part 1 of Publcation 30, ICRPrecommended a new method for internal dose estimation and presented someimportant data. In this report, comparison is made among methods for estimation of internaldose for the public from dietary. They include: (1) the new method suggested byICRP; (2) the simple and convenient method using transfer factors underequilibrium conditions; (3) the methods based on the similarities of severalradionuclides to their chemical analogs. It is concluded that the first method is better than the others and should beused from now on.
