[ RadSafe ] question about the HPS presentation titled "Physician into rad environment"

There was a University of Rochester researcher (Gilbert Forbes, I believe) who did work like this in the 1970s and 1980s. He had a beautiful whole body counter with some huge NaI crystals and a low-background counting room made of pre-WWII lead and steel. He did a number of studies on using K-40 for determining lean versus fat body mass. I don't know the full methodology, but I'm sure his papers are online somewhere.

Celi et al.,

Without doubt your interpretation is correct, unless probably you come across a very athletic female weight lifter or another woman athlet with more muscle than fat or a female bodybuilder with only muscles....... What an interesting topic for a research project.

Interesting work has been done by a friend of mine, who relatively shortly after the Chernobyl accident investigated the amount of Cs-137 in bodchurchies of "normal" people versus athlets and found that the latter had much higher concentrations in their body - I hope everybody on Radsafe knows about the similarity in biological behaviour of Cs(-137) and K(-40). You are free to explain this to our antinuclear experts. I am not sure that they will understand  this simple relation. Another former collegue The radiation risk therefore is significantly less for couch potatoes.....

I have no link, but his name was Heinz Oberhummer, he died last year. He was mostly engaged in nuclear physics, but also in the movement against privilegies of the church(es) in Austria. Together with another scientist he started quite a few years ago a TV program under the title "Who knows nothing has to believe everything." What a wonderful sentence, well applicable to all the discussions whether with our green friends or political agitation.

Best regards,

Franz

I am viewing this presentation and there is a slide that has this question on it Who is more radioactive, males or females?
I am assuming that since its on the page about K40 and since K40 is stored in the muscles the correct answer is males?
