i am starting my fourth round of rai-131. i had surgery on june 21,2005. (eight hours worth). after being told i couldnt be helped in munice, i was refered to goshen.Center for cancer care. i had 300mci my first time ,188mci my second time,and 300 mci my third time. in two weeks i will take another dose(amount yet to be determined). with out it i surly would have been a gonner by now. anything less than 200mci you can go home and keep yourself seperated from your family haveing direct contact with you for a few days but at least you at home and not the hospital!!!
