I'll take your word and expertise for it. My point is that the radiation levels are very samll and are not dangerous for humans or film.

I have at least one of the "radiactive" lenses and I'm very happy with its performance, given it ii a 40 year old lens

One of the things I have noticed is the use of the "Radioactive" term, whether it is true or not to raise the price at the auctions, given the "legendary status" you mentioned.
