A technique for fabrication of a flexible shielded afterloaded silicon
e nasal radiation carrier is described. The technique uses a rubber ba
se impression of the nasal cavity from which a silicone radiation carr
ier is made. Plastic tubes for afterloading of the radioactive sources
and a lead shield were incorporated into the carrier. The carrier per
mitted accurate location of the radioactive sources in the nasal cavit
y and reduced the radiation exposure.
