Which type of radiation is commonly found throughout the plant and has medium penetrating power?

Explanation:
Radiation types differ in how far their emissions travel. Beta particles are light and travel farther than alpha particles but not as far as gamma rays. They can penetrate skin and thin shielding, but are typically stopped by a few millimeters of aluminum, placing their penetrating power in the middle. In many plant environments, beta-emitting isotopes are common, so beta radiation is frequently encountered, which is why it matches the description of having medium penetrating power. Alpha is stopped easily by skin or paper, gamma travels far and needs dense shielding, and neutrons require different shielding materials, so they don’t fit as the middle option.
