In 1982, an article titled `Radioactivity in Cigarette Smoke' in the New England Journal of Medicine by T.H.Winters and J.R.DiFranza of the University of Massachusetts Medical Centre, provided the wake up call. They showed that cigarette contains radioactivity in the form of polonium-210 (Po-210) and lead-210 (Pb-210). They claimed that a person smoking 1 and 1/2 packs of cigarettes per day receives a radiation dose to certain regions of the lung equal to 300 x-ray films of the chest per year. Others estimated that the dose is over 70 times more. The dose rate depends on the radioactive content of the tobacco, the puff size and the frequency and number of cigarettes smoked.
