Releasing thyroid cancer patients from the hospital based on dose rate measurement after 131I activity administration

Abstract

The treatment of thyroid cancer generally comprises
total thyroidectomy and oral administration of radioiodine
(
131I). One consideration in this therapy is the radiation exposure
risks, which have led the Sri Lankan Regulatory Authority to
lay down criteria on releasing patients from hospitals when
the therapy procedure involves 131I activities greater than
1.85 GBq (50 mCi).
