Examples

1. Astronomical literature tends to write " gamma-ray " with a hyphen, by analogy to X-rays, rather than in a way analogous to alpha rays and beta rays.
2. :Different types of radiation have different ranges . alpha rays are stopped in a very short distance by air . gamma rays OTOH can go much farther.
3. Skin is sufficient to stop Alpha radiation, so I would assume that alpha rays were stopped by the watch parts and the radon gas amounts were neglegable.
