we had this question in a recent exam. does anybody know how to do this?
"Y-90, radioisotope of yttrium, is used in the treatment of localised cancer. it has a half-life of 64 hours. what percnetage of the initial dose would remain in the patient after 4 days?"
i got 33%, sum1 else got 35%, and another got 37% as the percentage of the initial dose.
just wanna know whose right.
