Question

Which of the following has the maximum penetrating power ?

• A. $\text{Alpha particle}$
• B. $\text{proton}$
• C. $\text{Gamma particle}$
• D. $\text{Posistron}$

Answer 1

The correct option is C $\text{Gamma particle}$

Gamma rays and x-rays are high-energy electromagnetic radiation (high energy photons). This classification of radiation has the greatest penetrating power.

Gamma rays are able to pass through several centimeters of lead and still be detected on the other side.

Hence,option C is correct.
