Which of the following arrangements of radiations is in the order of decreasing penetrating power?
- \(\alpha, \beta, \gamma\)
- \(\alpha, \gamma, \beta\)
-
\(\gamma, \beta, \alpha\)
- \(\beta, \gamma, \alpha\)
The correct answer is: C
Explanation
The alpha rays are the least penetrating, followed by beta rays, and gamma rays are the most penetrating.
in descending order \(\gamma, \beta, \alpha\)
