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

(a) `alpha, beta, gamma`

B

(b) `alpha, gamma, beta`

C

(c) `beta, gamma, alpha`

D

(d) `gamma, beta, alpha`

Text Solution

Verified by Experts

The correct Answer is:
A
Penetrating power is maximum for `gamma-rays`, then of `beta`-particles and then `alpha`-particles because basically it depends on the velocity. However, ionization power is in reverse order.
