Which type of radiation has the greatest penetrating power?
- Zac ZLv 71 month ago
Alpha radiation is helium nuclei - they can be stopped by a sheet of paper.
Beta radiation is electrons. They penetrate further but not very deep.
Ultraviolet and gamma radiation is electromagnetic radiation (energetic photons) and they penetrate a lot more. Of the two, gamma radiation is more energetic* which is why it is the radiation with the highest penetrating power.
* UV and gamma radiation essentially is the same thing (photons) but differ "only" in their energy (which is a function of wavelength/frequency).

alpha and beta are mostly particles.
