ActivityDecayCalc

ActivityDecayCalc is a handy tool made for professionals working with radioactivity and nuclear science. The app helps you easily calculate activity changes, decay rates, dose levels, and more with just a few inputs.

It includes useful calculators like build-up and decay during irradiation, decay-corrected counting rates, and inventory planning at regular times. You can also work out uncertainty, required starting activity, or cooling time to reach safe limits. Special tools like equilibrium checks, dose-rate estimates, and age-dating from ratios make the app versatile.

For deeper studies, it even offers a multi-step half-life table builder for different isotopes. Our aim is to make complex nuclear calculations simple, fast, and reliable for everyone.
