How does radioactive material get into a cigarette?
The tobacco leaves used in making cigarettes contain radioactive material, particularly lead-210 and polonium-210. The radionuclide content of tobacco leaves depends heavily on soil conditions and fertilizer use.
Soils that contain elevated radium lead to high radon gas emanations rising into the growing tobacco crop. Radon rapidly decays into a series of solid, highly radioactive metals (radon decay products). These metals cling to dust particles which in turn are collected by the sticky tobacco leaves. The sticky compound that seeps from the trichomes is not water soluble, so the particles do not wash off in the rain. There they stay, through curing process, cutting, and manufacture into cigarettes.Lead-210 and Polonium-210 can be absorbed into tobacco leaves directly from the soil. But more importantly, fine, sticky hairs (called trichomes) on both sides of tobacco leaves grab airborne radioactive particles.
For example, phosphate fertilizers, favored by the tobacco industry, contain radium and its decay products (including lead-210 and polonium-210). When phosphate fertilizer is spread on tobacco fields year after year, the concentration of lead-210 and polonium-210 in the soil rises.
What happens when I smoke a cigarette?
Research indicates that lead-210 and polonium-210 are present in tobacco smoke as it passes into the lung. The concentration of lead-210 and polonium-210 in tobacco leaf is relatively low, however, this low concentration can accumulate into very high concentrations in the lungs of smokers.
As it passes into the lungs, the smoke impacts the branches of the lung passages, called bronchioles, where the branches split. Tar from tobacco smoke builds up there, and traps lead-210 and polonium-210 against the sensitive tissues of the bronchioles. Studies show filters on ordinary commercial cigarette remove only a modest amount of radioactivity from the smoke inhaled into the lungs of smokers. Most of what is deposited is lead-210, but polonium-210 (whose half life is about 138 days) quickly grows in as the lead-210 (half life = 22.3 years) decays and becomes the dominant radionuclide. Over time, the concentration of polonium-210 directly on tissues of the bronchioles grows very high, and intense localized radiation doses can occur at the bronchioles.
Inhalation tests have shown that PO-210 is a cause of lung cancer in animals.
It has also been estimated to be responsible for 1% of all US lung cancers, or 1600 deaths a year.
The US authors analysed 1500 internal tobacco company documents, finding that tobacco companies conducted scientific studies on removing polonium-210 from cigarettes but were unable to do so.
"Documents show that the major transnational cigarette manufacturers managed the potential public relations problem of PO-210 in cigarettes by avoiding any public attention to the issue."
Philip Morris even decided not to publish internal research on polonium-210 which was more favourable to the tobacco industry than previous studies for fear of heightening public awareness of PO-210.
The more you smoke, the more radiation you have in your body..and it builds. The amount is significantly more than the levels in
Japan..scary stuff indeed.
Think carefully my friends...what are you smoking?

I should have told my uncle this. He died at age 96 after smoking 2 packs of either Camel, Chesterfield, or Pall Mall every day since he was 14 yrs. old living on the family's tobacco farm....I guess what the paid media says is true after all...Radiation will not hurt you......Be Happy, Don't Worry....
That's awesome, haha. One conspiracy I wouldn't mind being true

There is a conspiracy that the radiation in cigarette smoke is actually beneficial to the human body and prevents many diseases that non smokers get normally .
Government health organizations say smoking is bad because the big business owners and think-tanks figured out that smokers need far less health care than non smokers.
The source of tobacco’s polonium is all natural. It’s a decay product of radon that escapes from the ground, especially in regions with a lot of bedrock close to the surface or soil containing uranium-238. (On average, the authors say, the top five feet in each square mile of soil contains some 30 tons of uranium-238.)
I was familiar with the issue generally, having written about it 27 years ago. What I wasn’t aware of until reading this new piece by health physicists Dade Moeller and Casper Sun was that “a filter for removing it [polonium-210] from cigarette smoke has been available for more than 40 years.”
Below I will list just a few of the addictives that are inhaled with each puff of a cigarette.
DDT - An insecticide that was eventually banned
Acetone - This is usually found in nail polish remover
Butane - You can find this in your lighter fluid
Cyanide - By now we should all know that cyanide is a very deadly poison
Ammonia - Used to clean your home and the smell is awful and overpowering to the senses
Benzene - This product can be found in synthetic rubber and also used to make dye products
Arsenic - Another deadly poison that is often used to kill rats
Formaldehyde - An embalming fluid and teens often use it to get high
Naphthalene - Mothball ingredient
Nicotine - Nicotine was a poison that was once and may still be used to kill roaches
A few other key ingredients include Carbon monoxide and nitrogen oxides,

Roll ups can be even more harmful, sorry.
