1. What types of radiation are most dangerous to the outside body and indide and why

2. What is nuclear fission? what is nuclear fusion?

3. Alpha particles are easily stopped, and this makes them useful in smoke detectors, Americium-241, with a half-life of 433 years, is often used as the source of alpha particles. Why is alpha radiation used in this case? Why is a radioisotope with a long-half-life needed?
