alpha
Neutrinos.
The Least penetrating form of radiation is Alpha as it only travels 10cm in air and is stopped by paper. Alpha is also the most ionising, Beta is less ionising still and Gamma is the least ionising as photons carry no charge so they have less effect.
The gamma radiation is extremely penetrant.
1. Alpha Particles are the least penetrating, but do a great deal of radiation damage on the surface of what they hit.2. Beta Particles penetrate to a certain extent depending on their energy.3. Gamma Rays penetrate the most, and a Gamma source requires heavy (lead, etc.) shielding.

Gamma Ray
Gamma radiation
Alpha particles are the least penetrating form of radiation. However, that does not mean they are the least dangerous. Even though they can be stopped with only an inch or so of air, or even by our skin, if they are ingested and come into contact with sensitive body tissues, they can be dangerous, because they have the highest charge and the highest mass.
Alpha Radiation
Gamma radiation. Alpha radiation is the least penetrating, beta radiation penetrates and lasts longer than alpha but also "dies out" relatively quickly, but Gamma radiation will not only penetrate deep, but it will also stay long.
