My goodness, what a wall of text.
I do not know how to say it delicately, but it is not scientific.
Knowing the physics and characteristics of radiation and radioactive contaminations is one of my job requirements. I take classes on the subject.
You can say it anyway you want. I used to work in the fisheries industry as a biologist. Fire away.
PS: I’ve taken classes on the subject too, and performed experiments with radiation. It’s really not that obscure - the content is available in reliable websites online (i.e., EPA documentation)
