Sorry, I do not keep numbers in mind and it took me a long time to learn to
remember my own new telephone number...., but I can tell you that the
Brazil nuts are therefore "(in)famous", because they contain elevated
levels of Ra-226. I do not remember, how much it was, but I think it "very
unlikely" that it would be 500 Bq/kg. Maybe some people count the tritium
and C-14?
