It is assumed that short lived decay products are in equilibrium with their parent nuclides. But, for nuclide mixes other than those given in the Material Type pick list, activities can be entered directly. It is also possible to modify activity data after selection from the pick list. The Calculator uses the dose coefficients from ICRP 72. The new dose factors show significant differences from the old ones for the nuclides of interest.
All coefficients used are for adults.
For ingestion , there is no distinction between solubility classes in ICRP 72. The Risk Factor describes the risk of contracting fatal cancer per effective dose equivalent received. In addition, the organ doses for some important organs are shown, and the weighted contributions of these organ doses to the Committed Effective Dose and the Risk. Moreover, for each organ, the nuclide which is the major contributor to the organ dose, and its fraction of contribution to the organ dose is mentioned. The limited accuracy of the organ dose factors used may result in minor inconsistencies.
