Question
- A. High ionising power
- B. Low penetration ability
- C. Moderate penetration ability
- D. High energy
Answer
Moderate penetration ability
Explanation
Beta radiation has a moderate penetration ability, allowing it to pass through materials to a certain extent, making it ideal for thickness monitoring without excessive ionisation.
Common mistake
Misunderstanding Beta Radiation
Students often confuse beta radiation with alpha radiation, thinking both have similar penetration abilities.
Remember that beta radiation has greater penetration power than alpha radiation, making it suitable for thickness-control systems.
