Consider a particle , beta particle and ...

Consider a particle , `beta` particle and `gamma - rays` , each having an energy of `0.5 MeV` . In increase order of panetrating power , the radiation are .

A

`alpha,beta,gamma`

B

`alpha,gamma ,beta`

C

`beta,gamma,alpha`

D

`gamma,beta,alpha`

Text Solution

Verified by Experts

The correct Answer is:
c
The penetrating power is dependent on velocity. For a given energy, the velocity of `gamma`-radiation is highest and `alpha`-particle is least.
