Radiation found in cigarettes

The tobacco industry was aware for decades that smoke from cigarettes was radioactive and potentially carcinogenic, but concealed that information from the public, according to a new research. Scientists at UCLA have discovered that the tobacco industry began studies on possible effects in smokers by radioactive particles of the element polonium-120, in the early 1960's. 

The findings were based on an examination of internal documents of the companies in the industry, which had not been studied previously. Scientists from UCLA estimate that the radiation may cause between 120 - 138 deaths per 1000 regular smokers over a period of 25 years.
