Lots of people are discussing all sorts of weird souces of radioactive material to use in a detector for an RNG. None of this is necessary. Scientific supply houses will happily sell you small calibrated sources for use in your lab, classroom, or in our case, machine room (:-). There is no need to find objects to dismantle or silly dangerous radioactive sources. You can get a source that produces exactly as much activity as you need very cheaply. Perry
