About This Tool

Model radioactive decay and other exponential decay processes. Given any two of half-life, initial quantity, remaining quantity, or elapsed time, calculate the rest. Visualize the decay curve and understand the mathematics behind exponential decay.

How to Use

  1. Enter the half-life and initial quantity
  2. Specify either elapsed time or remaining quantity
  3. View the calculated result and decay statistics
  4. Examine the decay curve graph
