I had to X-ray some stuff for work today and since I was qualifying one of my V-742 dosimeters and had never seen the insides of one I stuck it in the X-ray machine. It was pretty cool to see the ion chamber, the meter needle and how they sealed both ends so well that they last 45 years.
And oh yeah, it got a 20R dose of radiation!
