Management of biological waste of patients after radionuclide therapy

Radioactive waste management is a modern-day issue in terms of radiation safety due to the development radionuclide therapy, emergence new radiopharmaceuticals, radionuclides, and treatment methods, which allow for therapy day hospital. According current domestic regulatory methodological support biological wastes generated during patient’s metabolic activity after injection radiopharmaceuticals refer liquid radioactive waste. These must be collected kept decay hospitals safe levels before being spilled into municipal sewerage. It requires additional expenses hospital making special To increase availability it necessary update requirements nuclear medicine departments, considering volume activities different diagnostic therapeutic radionuclides patients. On basis findings, possible evaluate feasibility binding requirement sewerage departments therapy. In this work, excretion used therapy: 89 Sr-dichloride, 223 Ra-dichloride, 131 I-MIBG, 177 Lu-PSMA, 225 Ac-PSMA was studied based on published data determine As results preliminary computations, some procedure will not lead generation from patients system usual operating condition strictly necessary. For example, estimations showed small with limitation 50 beds can enough reduce level specific wastewater one patient Sr-chloride Ra-dichloride. order revision each department differentiated approach ensure environment protection people, continue research including modeling realistic scenario staff exposure confirmed experimental results.
