Both of these PDFs of Radiological Instruments for Civil Defense are Civil Defense Technical Bulletins. TB 11-20 to be exact. One is from September 1955 and the other October 1958
I have covered radiological instruments before and have a couple videos on the basic use of these machines, calibration of the meters, as well an article on personal dosimetry.
If you are still unsure of what radiation actually is I have a pretty good article on that also.
As a trained responder, I would rather deal with a radiological emergency that a chemical or biological incident of the same scale. Nuclear events follow specific physical rules. I can determine a safe level get out my meter and set a flag at the exact spot where it is unsafe to pass. With a chemical you can’t do that.
However, I find that in the prepping community and to a much greater extent the base population, false information and fear cause most people to fear radiological events much more than chemical.
To easy those fears by education, I have a lot of information on this website dealing with nuclear incidents. I hope they are helpful to you.
