After radiotherapy people are concerns about the radiation risk that they pose to themselves as well as to others. In case of external radiotherapy no special precautions are needed to be taken.

► Proper hand washing after using the toilet.
► Using separate eating utensils and towels.
► Drinking plenty of fluids to flush out the radioactive substance from the body
► Avoiding kissing and sexual contact.
► Avoiding prolonged contact with infants, children and pregnant women.
