«Liquid contamination should in future be included in the NAMS accident quantification. The problem here, which is beyond the scope of the present paper, is how to estimate the radiological equivalences for the various isotopes and to return a value for the magnitude, given also the variety of paths by which activity might eventually be ingested.»
