RE: Po-210 in tobacco

[Bernard L Cohen <blc+@PITT.EDU>]

	About 25 years ago, Ed Martell at National Bureau of Standards in

Boulder, CO published a series of papers purporting to show that the lung

cancer from smoking was due to the Po-210 in the tobacco. This theory was

debated fairly extensively, and I thought the final conclusion was that

Martell was wrong - it was chemical effects rather than radiation that was

causing the lung cancer. What is causing this new flurry of interest?
