Beta particles are:

Beta particles are:

• A. Ionizing radiation like X-rays.
• B. Deadly radiation.
• C. Large particles that easily pass through protective gear.
• D. Having weight and mass.

Answer: (A)

Beta particles are a form of ionizing radiation, which is the key idea being tested. They are high-energy electrons (or positrons) emitted by radioactive decay. Because they ionize atoms as they move through matter, they share this damaging property with X-rays, so describing beta radiation as ionizing radiation like X-rays is accurate. They aren’t large particles; they’re relatively light and have mass, but the defining feature for safety and classification is their ability to ionize, not their size. Their ability to penetrate protective gear is limited, and they’re not inherently deadly—the danger depends on dose and exposure.
