Radioactivity Concentration in the Air during Peptide Receptor Radionuclide Therapy with [¹⁷⁷Lu]Lu-oxodotreotide

Abstract

[¹⁷⁷Lu]Lu-oxodotreotide is a peptide receptor radionuclide therapy (PRRT) agent. The concentration of radioactive materials in the air was measured on patients during treatment with this drug. The concentration of lutetium (¹⁷⁷Lu) in the air was below the detection limit in the administration room and the waiting room, while it was detected in some cases in the special measures patient room. However, the detected levels were well below the concentration limits on radioisotopes specified in the second column of Appendix 3 of the Ordinance for Enforcement of the Medical Service Act.
