Question
- A. High ionising power
- B. No mass or charge
- C. Low energy
- D. Short wavelength
Answer
No mass or charge
Explanation
Gamma radiation has no mass or charge, allowing it to pass through materials with minimal interaction, which contributes to its high penetrating ability.
Common mistake
Gamma Radiation Characteristics
Students often confuse the ionising power of gamma radiation with its penetrating ability, thinking it is strongly ionising.
Remember that gamma radiation is weakly ionising due to its high energy and ability to pass through materials, but it does not cause as much ionisation as alpha or beta radiation.
