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.
