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

Next generation for Phased Array UT is here now with FMC/TFM! Have higher resolution imaging, impr
...
oved signal to noise ratio, characterize, size and analyze defects better with access to several wave mode views and save raw FMC data for higher quality analysis.  Some of the benefits are:
  • Beautiful Image! Easier to understand what you're looking at
  • Completely focused in entire image or volume
  • Much easier to define setups before inspection
  • Easier to decipher geometry echoes from real defects
  • Oriented defects (e.g. cracks) are imaged better
  • See image from different wave modes from one FMC inspection
  • FMC data can be reprocessed/analyzed without going back to the field
