Many cigarettes contain radioactive polonium from the use of phosphate/apatite fertilizers. The National Institutes of Health lists tobacco as by far the largest source of radiation for the American public.
A common argument for organic cigarettes is that they don't contain as much radioactive material, and are therefore much safer:
Surprisingly, radiation seems to be the most dangerous and important factor behind tobacco lung damage. ... The unnecessary radiation delivered from soil-damaging, synthetic chemical fertilizers can easily be reduced through the use of alternative phosphate sources including organic fertilizers. ... Tobacco smokers can also use this information to avoid radioactive brands of tobacco. American Spirit is one of a few companies that offers an organic line of cigarettes, and organic cigars are also available from a few companies. - Radioactive tobacco
The best thing about organic cigs is the fact that they aren’t allowed to use radioactive fertilizer. This means that you won’t get a large dose of radiation like regular cigs. ... Actually smoking organic cigarettes is MUCH better than smoking commercial american grown cigarettes. American tobacco growers use phosphate fertilizers that are tainted with radioactive Polonium and Lead. The metals get stuck in bifurcations in our lungs which results in large amounts of ionizing radiation. This radiation causes about 97% of all lung cancers. Organically grown tobacco makes no use of contaminated fertilizer and hence you are ALOT LESS LIKELY to get cancer from smoking. ... Get all the chemicals out and the radioactive fertilizers and you have the same stuff or close to what the american indians were smoking and they had NO cancer. - Blog comments
Radiation comes from commercial tobacco because it is grown with radioactive fertilizers that leave Polonium 210 and Lead 210 concentrated in the tobacco. This is the major cause of cancer. Organic tobacco lacks these radioactive carcinogens, (yes it contains dozens of other carcinogens so it is not safe) but those dozens of other carcinogens only cause 10% of tobacco’s cancerous effects.

Is there any truth to the claims that the "organic" label implies a lower amount of radiation?
