Calculate radioactive decay and ingrowth of uranium and its decay products for a variety of nuclide mixes found in the nuclear fuel industry.
Covers the natural U-238 and U-235 series, and the artificial U-236 and U-232 series.

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