holy crap but makes sense. When I was a kid they did not initially use the lead covers and then later they did. Seems like between 70 and 80 they started treating them much more seriously.
And then someone pointed out the little measuring machine with the sliding parts on the ruler works just as well without the whole “staring into a primary x-ray beam all day” thing
