I have one, and it looks like some kind of test chart. I have no instructions.

It's an 11x14 piece of transparent material with some sort of black emulsion on it. I suspect it should be contact printed, but what am I supposed to find? Maximum contrast of a paper?

I think it is supposed to test the strength of gamma radiation. Look about half way down the page...

It's the little, rather evil looking dude that lives under your computer. Eats unwary digishooters
