Answer
Alpha radiation
Explanation
Alpha radiation is particularly dangerous when emitted from contamination inside the body because it is strongly ionising and can cause significant damage to internal tissues.
Common mistake
Contaminated Object Emission
Students often think that a contaminated object stops emitting radiation once it is removed from the radioactive source.
Emphasize that a contaminated object continues to emit radiation because it contains radioactive atoms, regardless of its location.
