Krypton Kr 81m Levels and Effects while Breastfeeding
Summary of Use during Lactation
Elective diagnostic nuclear medicine procedures should be delayed until the patient is no longer breastfeeding.[1] Information in this record refers to the use of krypton Kr 81m as a diagnostic agent. The International Commission on Radiological Protection states that breastfeeding need not be interrupted after administration of krypton Kr 81m gas.[2]
Drug Levels
Krypton 81m is an inert gas that is a gamma emitter with a principal photon energy of 0.19 MeV. Because of its rapid decay, the effective half-time of lung elimination is equal to the physical half-life of 13.1 seconds. Peripheral krypton 81m radioactivity is exhaled after the first passage through the lungs.
