For dose calculations for adults, the Uranium Radiation Individual Dose Calculator offers more options. If organ-specific doses for adults are required, see the Uranium Radiation Organ Dose Calculator.
The calculator only determines exposure to radiation; the chemical toxicity of uranium is not covered (see Uranium Toxicity).
The calculator only determines doses to exposed individuals. For collective dose calculations, see the Nuclear Fuel Population Health Risk Calculator.
The calculator only determines doses for situations, where the pathway and the rate of exposure to a contaminant is known. Otherwise, some more sophisticated software has to be used (see Uranium Mine and Mill Resident Individual Dose Calculator and Dose calculation software).
The parameters used for the calculation can be set in the Input, Exposure Parameters and Consumption Parameters tables. These parameters show reasonable initial values which can be modified as needed. There are no other hidden parameters used in the calculation. Any assumptions made for the calculations are described on this page.
The Calculator uses the dose coefficients from ICRP 72. At present, the dose coefficients of ICRP 60/61 (1990) are widely used, while revised dose coefficients have been presented for workers in ICRP 68 (1995) and for the public in ICRP 72 (1997). The new dose factors show significant differences from the old ones for the nuclides of interest.
The calculator simplistically uses only the committed effective dose coefficients, rather than the organ specific dose coefficients. It thus does not perform the exact calculations prescribed by ICRP; the results are approximations only.
Cautionary Notice:
The user should be aware that several of the parameters used in the biokinetic model for the dose factors are subject to variations and uncertainties, while the calculator produces only one result, without indicating these elements of uncertainty.

Solubility Class | Chemical form | f_{1} | |
---|---|---|---|
age <= 1 y | age > 1 y | ||
F | UF_{6}, UO_{2}F_{2}, UO_{2}(NO_{3})_{2} | 0.04 | 0.02 |
M | UO_{3}, UF_{4}, UCl_{4} | 0.04 | 0.02 |
S | UO_{2}, U_{3}O_{8} | 0.02 | 0.002 |
For decay products, the calculator assumes the same solubility class as for the parent nuclide.
For ingestion, there is no distinction between solubility classes in ICRP 72.

Note for StrlSchV 2001 (Germany): Add another 115 ltr/year to the drinking water amount for age 3 months, if the infant receives no breastfeed (not shown in the pick list).
