I have two magnesium-thorium castings that I want to dispose of. Each weighs
about 25 pounds (11 kg). I am trying to estimate the amount of thorium in
each. These were fabricated 30 - 40 years ago, and I have nothing to tell me
the percentage of thorium in them.
Does anyone have information on mag-thor alloys, such as what an average
thorium content might be?
Incidentally, I've measured about 2 mrad/hr (0.02 mGy/hr) window-open, and
about 1 mrad/hr (0.01 mGy/hr) window-closed at the surface of these castings.
