>Radiation is the ONLY way an active material can be quickly identified. This tool has been ignored. I'm trying to get you and other people to use it
Understood, the system I'm building will have at least one GM tube of equal or better sensitivity to the LND7313 you used in your experiment.... in fact that instrument arrived yesterday. Setting up a quick IR temp measurement from inside a hot pressurized vessel is neither cheap nor easy... I'm trying to determine if the radiation only is sufficient or if I should stick to my original plan to put in IR temp sensing of the material under test. Its looking like a robust reliable IR sensing of small targets inside the chamber will be about $5K and 4+ weeks of lead time. The lower cost IR stuff won't go to high enough temperatures to be useful... (As others have pointed out one needs to be above the curie temperature of the material being tested.) Paul
