The least penetrating form of radiation is a. beta radiation c. alpha radiation b. gamma radiation d. x rays

The correct answer is option (C) Alpha radiation

Explanation:

The types of radiation which are alpha, beta and gamma radiation have different penetration power.

Penetration power is the ability of each of the types of radiation to pass through matter. The more they penetrate, the more dangerous they will be.

Alpha has the least penetration power because it has large mass size

Gamma has the highest penetration power because it has no mass size

Beta has the medium penetration power because it has a small mass size

Therefore, the penetration power is affected by the size of mass they carry.
