I am very very interested in why you didn't post the second paragraph of your Wikileaks reference?
The median lethal dose (LD50) for acute radiation exposure is generally about 4.5 Sv. The committed effective dose equivalent 210Po is 0.51
µSv/Bq if ingested, and 2.5 µSv/Bq if inhaled. Since 210Po has an activity of 166 TBq per gram (4,500 Ci/g) (1 gram produces 166×1012
decays per second), a fatal 4.5 Sv (J/kg) dose can be caused by ingesting 8.8 MBq (238 microcuries, µCi), about 50 nanograms (ng), or inhaling 1.8
MBq (48 µCi), about 10 ng. One gram of 210Po could thus in theory poison 20 million people of whom 10 million would die. The actual toxicity of 210Po
is lower than these estimates, because radiation exposure that is spread out over several weeks (the biological half-life of polonium in humans is 30
to 50 days) is somewhat less damaging than an instantaneous dose. It has been estimated that a median lethal dose of 210Po is 0.015 GBq (0.4 mCi),
or 0.089 micrograms, still an extremely small amount.
NOte the dosages - 2.4 ugSv/Bq if inhaled. That means all at once!
Now let us look at the dosage that smokers are exposed to:
The annual effective doses were calculated on the basis of (210)Po and (210)Pb intake with the cigarette smoke. The mean values of the annual
effective dose for smokers (one pack per day) were estimated to be 193 and 251 microSv from (210)Po and (210)Pb, respectively.
That is the dosage PER YEAR!!! And again Polonium 210 has a half-life of 138 days.
Nice try - but its the same trick used over and over again. The fact remains: The poison is in the DOSE. Not the substance. Even water is toxic if
you drink enough of it.
I would really like to know if you are deliberately trying to mislead people and instill fear or if you honestly believe that the Polonium 210 in
tobacco is at sufficient quantities to cause death?
If the Polonium 210 in tobacco were at sufficient quantities to cause death - then every smoker would develop lung cancer and die. The fact is that a
hard-core, heavy smoker still has only a 17 % lifetime chance of developing lung cancer.

So, you said it has a half life of 138 days. That means that once ingested or inhaled it will remain active for 138 days.
You said the lethal dose active at one time would take a year to accumulate at 1 pack a day.
If someone smokes 2 packs a day, he achieves the same lethal dose in 182.5 days, 44 days over the half life. So if you smoke a little over two packs
a day, you're a dead man in 4 and a half months....
There is also something to be said for dosages, especially when it comes from radiation. If you are radiated but below the minimum lethal dosage, you
claim no damage is done... and that is simply not true. It wears down and has affects that accumulate, especially when the stream of damaging
pollutants is a constant, like smoking.
If I were to take slightly less than lethal doses of Po everyday, I would die in under a week.
Not sure you know what you're talking about... just saying.
Oh and we're only talking one foreign substance of potentially hundreds depending on what exactly you smoke. Cigars, Ciggarettes, Cloves, Pipe
Tobacco, they all have different chemical blends in them.
I'm not saying that all smokers die, I'm not saying that this is 100% going to kill you every time, but I am saying that everyone's physiology is
different, and the amount they can or can't withstand of a foreign body varies. What is considered a safe dose to one man, may be a lethal dose to
"Safe Dose" is calculated by an average. There are many hundreds of thousands of people who can with stand below this dosage, as there are some that
can withstand a slightly greater dose.
In any way, the health risks are great.
Yes, I am a smoker. No, I haven't seen a single person use an electronic cigarette and quick smoking real ones. My mom tried to quit, she quit the
e-cigarette. My brother tried to quit, he smokes his e-cigarette until it's empty, and then proceeds to smoke a pack.
The amount of nicotine saturation levels one gets from e-cigarette's is likely much greater than just smoking regular cigarettes unless used as
instructed. However, most people smoke 3 packs worth of nicotine from an e-cigarette in the amount of time they would have smoked an entire pack of
cigarettes. Then when they are done, they proceed to smoke a pack of cigarettes.
Taking the amount of nicotine saturation in the body to "nicotine poisoning" levels.
I'm not saying they can't work if used responsibly, I'm just saying that more often than not, like anything in life, it's abused rather than used
I'm not supportive of a ban, however, I understand the sentiment. I honestly think cigarette's should be out right banned. Why do we allow
corporations to sell things that will ultimately kill you and provide no noticeable benefit? Before I smoked I was fine... My stress levels were
cool, now my stress levels are dependent on my nicotine levels. My health becomes dependent on my nicotine levels as well.
This places me in a situation where it's like, die or do something dumb, or sit in a room by myself clawing my eyes out over a stupid craving I
otherwise shouldn't have. Yes, it was my choice to start smoking, but it's much less of a choice to quit... and that is by design, so why is it
allowed, better yet, promoted?
