Performance of graphene oxide and coconut shell activated carbon for 131i isolation from delay tank

Iodine-131, with a half-life of 8 days and about 971 keV excess energy, is the well-known radionuclide used for hyperthyroidism and thyroid cancer. Due to its considered low-medium half-life, differentiated thyroid cancer (DTC) patients administered with high energy 131I need to be isolated until...
