Knowledge Hub · I-131 Therapy
The clinical + regulatory framework around radioactive-iodine therapy.
I-131 therapy sits inside a two-layer framework: the clinical guidelines (ATA, EANM, SNMMI) defining who, when and how much; and the regulatory chain (AERB SC/MED-4, IAEA SRS 63, ICRP Publication 94) defining ward design, waste handling and patient-release criteria. Six anchor documents cover both.
Standards framework
Six documents that shape the therapy programme.
EANM procedure guidelines for therapy with iodine-131 (I-131) (2022)
The European Association of Nuclear Medicine's updated procedure guideline for I-131 therapy — indications for differentiated thyroid cancer ablation, hyperthyroidism, benign nodular disease, activity selection, patient preparation, dosimetry-based vs empiric activity choice.

American Thyroid Association Management Guidelines for Adult Patients with Thyroid Nodules and Differentiated Thyroid Cancer
The ATA management guideline — the definitive reference on when radioactive-iodine therapy is indicated in DTC, activity-selection tiers by risk stratification, and post-ablation whole-body-scan workflow.
Open standard →
SNMMI/EANM Practice Guideline for Post-Therapy Imaging in DTC Patients
Post-therapy planar + SPECT/CT scan workflow after I-131 ablation. Anchors the "why we image day-3 to day-10 post-ablation" answer and defines the imaging QC that closes out an ablation cycle.

Safety Code for Nuclear Medicine Facilities
India's regulatory code for nuclear medicine — includes the therapy-ward design requirements, isolation-room air-change rate, waste-handling for I-131 patient excreta, and the discharge-activity thresholds patients must fall below before release.
Open standard →
Release of Patients After Radionuclide Therapy
The IAEA guide on the calculations, hospital-stay logic, radiation-protection advice to household + travel companions, and hospital-discharge dose-rate thresholds for I-131 therapy patients.
Open standard →
Release of Patients After Therapy with Unsealed Radionuclides
The ICRP framework document behind IAEA SRS 63 — dose constraints for family members and the public, the dose-rate calculation logic feeding the AERB / IAEA release criteria.
