[Leakage of gaseous 125I during radioiodination using Na125I].
Gaseous 125I was present at 48 +/- 33 and 122 +/- 15 kBq in Na125I vials (74 MBq) purchased from Amersham and New England Nuclear, respectively. Gaseous 125I leaked to the amount of 37 +/- 22 and 130 +/- 67 kBq during radioiodination by the chloramine-T and the enzymatic methods using 18.5 MBq Na125I, respectively. Radioactive wastes from radioiodination using 18.5 MBq Na125I evolved about 5.5 kBq of gaseous 125I in first day of storage.
