This is Dr. David
this sounds like a bone scan.
which tends to use technicium 99 which is very low dose and usually is eliminated in the urine and has a very short half life.
this radiation decays very quickly and is not a risk to the family
washing close warn in the washing machine is enough and flushing the toilet twice after patient use is enough safety precautions.
the family is not at risk from bone scan technetium 99 radiation from a bone scan.
let me know if you have questions.
Family member had an MRI scan of the whole body and injected radioactive substance to detect cancer of the bone. Would there be any radioactive leftovers in dishes, carpets or table and if so what is the best way to clean it?
no, there would not be any radioactive left on dishes carpet or table.
you don't have to worry about this.
we all get exposed to radiation just living on earth.
we all get about 3-5 mSv worth of radiation each year just living on planet earth.
you don't have to worry about the radiation from his bone scan.
