Vedclass · Answer

(A) The penetrating power of radioactive radiations depends on their mass and charge. Alpha particles $(\alpha)$ are heavy and carry a $+2e$ charge, making them highly ionizing but having the least penetrating power. Beta particles $(\beta)$ are high-speed electrons with much smaller mass, giving them greater penetrating power than $\alpha$ particles. Gamma rays $(\gamma)$ are high-energy electromagnetic waves with no mass and no charge, allowing them to have the highest penetrating power. Specifically, the penetrating power of $\gamma$ is approximately $100$ times that of $\beta$, and the penetrating power of $\beta$ is approximately $100$ times that of $\alpha$. Therefore, the increasing order of penetrating power is $\alpha$ < $\beta$ < $\gamma$.

Which of the following is in the increasing order for penetrating power?
