How does a gravitational field affect alpha particles beta particles and gamma radiation?

Answer 1

Gamma rays are a form of electromagnetic radiation, and therefore travel at the speed of light.

This would require an extremely massive gravitational field, i.e. an extremely massive object, on the scale of stars.

The same goes for beta particles; electrons and positrons, who already travel at nearly the speed of light due to their low mass.

Alpha particles, however, due have some mass, and therefore travel at only 5% the speed of light, still fast enough to escape the Earth, but not fast enough to be affected by larger planets, perhaps.

Answer 2

A gravitational field affects all these particles and radiation in the same way, by exerting a force on them that depends on their mass (and charge, in the case of alpha and beta particles). However, due to their different properties, they will be affected differently. For example, alpha particles are more massive and charged, so they will be more affected by gravity compared to beta particles and gamma radiation.
