Due to the incorporated radioactivity, patients must remain hospitalized until radiation levels are deemed safe, according to national regulations. This is particularly problematic for patients who require hemodialysis (HD). While contamination of dialysis waste after radionuclide therapy is generally well recognized, a critical gap remains regarding its duration and extent. This poses risks for patient management and outpatient staff.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Purpose<\/jats:title>\n                    <jats:p>This study aims to demonstrate the problems with classifying residual waste and provides arguments for appropriate regulation.
