Radioactive Decay Rate Calculator
The Radioactive Decay Rate Calculator will calculate the:
- Decay rate of a radioactive sample when the initial number of nuclei and half-life are known
| The radioactive decay rate as a function of time R(t) is Bq [Becquerel] |
| Radioactive decay rate as a function of time calculation |
|---|
| R(t) = ln 2/T1/2 ∙ N0 ∙ e-ln 2/T1/2 ∙ t R(t) = / ∙ ∙ e-/ ∙ R(t) = ∙ ∙ e- ∙ R(t) = ∙ ∙ e R(t) = ∙ ∙ R(t) = |
| Radioactive Decay Rate Calculator Input Values |
| Initial number of atomic nuclei (N0) |
| Half-life of radioactive element (T 1/2) s [second] |
| Time elapsed since the beginning of process (t) s [second] |
Please note that the formula for each calculation along with detailed calculations are available below. As you enter the specific factors of each radioactive decay rate calculation, the Radioactive Decay Rate Calculator will automatically calculate the results and update the Physics formula elements with each element of the radioactive decay rate calculation. You can then email or print this radioactive decay rate calculation as required for later use.
