Decay and ingrowth
Decay any of 1,500 radionuclides with full chains, branching fractions and metastable states. Watch Tc-99m grow in from Mo-99, Ac-225 reach equilibrium with its daughters, or Lu-177m linger in a Lu-177 vial.
Built on the logic of radioactivedecay (opens in a new tab). Research and education only.

What is Decay and ingrowth lab?
Runs in your browser
The Decay lab decays any of about 1,500 radionuclides with full chains, branching fractions and metastable states using ICRP-107 data through radioactivedecay, so you can watch Tc-99m grow in from Mo-99 or Ac-225 reach equilibrium with its daughters.
Key features
- ICRP-107 nuclear data via radioactivedecay
- Full progeny chains, branching fractions and metastable states
- Activity versus time charts and tables
Frequently asked questions
What is ingrowth?
Ingrowth is the build-up of a radioactive daughter from its parent, such as Tc-99m growing in a Mo-99 generator. The Decay lab calculates it with the Bateman equations.
