Beta radiation predominantly affects which areas?

Explanation:
Beta radiation has limited penetration into matter; beta particles travel only a short distance in tissue and can be stopped by a thin layer of material, like skin. Because of this, external beta exposure mainly affects the outer surfaces—the skin—and can also impact the eyes and other exposed extremities (hands, arms). Deeper organs such as the lungs or digestive system aren’t the primary targets of external beta exposure; they would be affected mainly if the beta-emitting material is inside the body (inhaled or ingested). So the areas most affected by external beta radiation are the skin, eyes, and extremities.
