What is the decay rate of tritium?
When tritium decays, it changes into an isotope known as helium-3. This decay process changes about 5.5 percent of the tritium into helium-3 every year. The time that it takes a radioactive isotope to decay to half the original amount is called the half- life. Tritium has a half-life of 12.3 years.
What percentage of a radioactive sample will remain after one half-life?
grams of this nuclide, how many grams of the nuclide will be left after 20.0 days?…Radioactive Decay Rates.
| Number of Half-Lives | Percentage of Reactant Remaining | |
|---|---|---|
| 1 | 100%2=50% | 12(100%)=50% |
| 2 | 50%2=25% | 12(12)(100%)=25% |
| 3 | 25%2=12.5% | 12(12)(12)(100%)=12.5% |
