Common mistake
Ionising Power Confusion
Students often confuse the ionising power of alpha, beta, and gamma radiation, thinking they are similar.
Remember that alpha radiation is strongly ionising, beta radiation is moderately ionising, and gamma radiation is weakly ionising. Use a table to compare their properties.
