RT of a valve body

Is it feasible (possible) to examine by RT (gamma ray) the body of a PCV (Pressure Control Valve) to point out the condition of its internals, in the following conditions:
- PCV diameter: 2"
- wall thickness : 20mm
-PCV is in operation and the body valve temperature is 185 degree Celsius?
Is there radiographics films that can be used in this conditions (185 degree Celsius)? If not, are there compensatory measures to carry out the purpose of the examination?
Thank you!

Re: RT of a valve body Insulate your cassette.
Use CR with image plates to reduce exposure time. Should get a good shot with Ir 192
