Re: Toxic Trivia

["David Whitfill" <DWhitfil@kdhe.state.ks.us>]

Philippe Duport gives a good reply to your question. In addition, the
tobacco leaves have an ideal surface for the collection of the longer-lived
decay products of radon (Pb-210 and Po-210). Page 94 of NCRP 45, page 94,
has the following:

"In addition to a dose to the lungs, cigarette smoke also contributes a
substantial fraction of the Pb-210 and Po-210 to the body of a smoker,
since both these elements are volatile at the burning temperature of
tobacco (about 1500 deg K). For a person smoking one pack per day,
cigarettes can account for 40 % of the total Pb-210 intake."

Does anyone know the chemical form of polonium in tobacco in cigarettes?
In the
smoke that is inhaled?  In the lungs after deposition?  Al Tschaeche
