Determine the radiation dose for an individual that is exposed to a known amount of uranium and/or its decay products.
For a variety of nuclide mixes found in the nuclear fuel industry, this calculator covers ingestion, inhalation, external exposure from contaminated soil, and external exposure from a point source. Calculations can not only be performed for actual exposure situations, but also for future scenarios, taking decay and ingrowth of decay products into account.

Enter the parameters and click the "Calculate" button below. HELP
Numbers can be entered in exponential notation: 5 · 10-6 = 5e-6
"t" means metric tonne.
