Decontamination
All items, which come into contact with a labeled probe, should be
decontaminated before re-use. In many cases, a short rinse in water will be
sufficient. In some instances, however, further decontamination procedures
will be required.

Meshes

The quantity of radioactivity adhering to the mesh can be minimised by
leaving the mesh in with the membrane throughout the washing
procedure. Any radioactivity remaining can then be stripped from the
mesh by the following procedure:
1. Strip wash the mesh by incubating it in distilled water at 65°C in a
shaking water bath for 15 minutes. Repeat.
2. If the mesh is still contaminated, soak it in a diluted solution, such as
Decon 90, overnight.
3. Remove the detergent and proceed with two washes in distilled water
for 10 minutes each.
4. If the mesh has been decontaminated, no further action is necessary. If,
however, the mesh is still contaminated, it will be necessary to leave it
to decontaminate in Decon 90 for a longer time period.
5. Meshes should be allowed to dry flat between uses.
