Cigarette smoke is toxic. But does the smoke also contain radioactive particles?
Cigarette smoke contains more than 50 chemical compounds that are carcinogenic, and the smoke indeed also contains radioactive particles that remain in the lungs and can cause cancer.
There are sticky hairs on tobacco leaves, where radioactive particles from the air stick to it. Once they are stuck, it is difficult to get them off again. The plants also absorb radioactive elements through their roots.
