Common mistake
Misunderstanding Radiation Absorption
Students often confuse the materials that can absorb or reduce different types of radiation, thinking that the same material is effective for all types.
To fix this, students should study the specific properties of alpha, beta, and gamma radiation, focusing on which materials are effective for each type. For example, paper can stop alpha particles, while lead is needed for gamma radiation.
