Question
The New Horizons spacecraft, launched in 2006, spent 9.5 years on its journey to Pluto. It derives its electric power from the heat generated by 10 kg of 238Pu, which has an activity of 6.3 × 1015 Bq. Each decay emits an alpha particle with an energy of 5.6 MeV. What is the total thermal power generated by this plutonium source?

- A radioactive sample with a half-life of 5.3 weeks has 1.04e+15 nuclides present in the initial sample. a) What is the initial activity of this sample?

This radon isotope in turn decays by alpha emission with a half-life of 3.82 d. If this process continues for a time much longer than the half-life of 222Rn, the 222Rn decay rate reaches a limiting value that matches the rate at which 222Rn is being produced, which is approximately constant because of the relatively long half-life of 226Ra.
