I wish that I could recall the details of the paper I’d read years ago. It was in NJ in a nondescript building housing research element of the MP, as I recall. Unrelated to this case (as far as I know), but germane to how radiation sites exist in populated areas, particularly NJ.
This is going to nag at me and cause much distraction over the weekend...
It’d be interesting to read if you find it. Maybe pass it on to that guys fb page if you can find that.
