Question

Consider `alpha-, beta`- particles and `gamma-` rays, each having an energy fo `0.5Mev` in increasing order f penertation power, the radiations are:
A. `alpha, beta, gamma`
B. `alpha, gamma , beta`
C. `beta, gamma , alpha `
D. `gamma, beta, alpha`

Answer 1

Correct Answer - a
For given energy , the radiations in the increasing order of penetrating power are `alpha lt beta lt gamma `
