ICRP Publication 94: Release of Patients after Therapy with Unsealed Radionuclides (Ann. ICRP 34 (2), 2004)

After some therapeutic nuclear medicine procedures with unsealed radionuclides, precautions may be needed to limit doses to other people, but this is rarely the case after diagnostic procedures. This book recommends that young children and infants, and visitors not engaged in direct care or comforting, should be treated as members of the public.
