I'm afraid radiation is not so good as giving up smoking first
Carcinogen or toxicant is 250 at more least kinds in the known cigarette.
The smoker's lung cancer mortality is more than ten times of the non-smoker's.
80%- 90% of the lung cancer death relates to smoking.
210 for a microgram of polonium can kill a person.
It equivalent to does X-ray chests 300 times a year completely to smoke 1.5 packs of cigarettes every day.
Mention nuclear radiation, whom people expect the atomic bomb, hydrogen bomb explode often, Hiroshima and cut the intersection of promise and Pele, terrific incident these seem very much remote from us. The nuclear leakage of nuclear power station of Fukushima of Japan until recently, did not let a lot of people realize, this kind of terrible things that can not see, can't feel, smell may come by us originally, then very panic.
In fact, in daily life, nuclear radiation is ubiquitous. The most unexpected nuclear radiation source, it may be a cigarette.
Is the cigarette poisonous? Radioactive material polonium 210 exists
In 1964, Harvard University researchers found, contained micro- radioactive material polonium 210 in the cigarette. By materials radioactive,but cigarette lighting later, polonium 210 can volatilize a portion to become smog, suck into the lung, is worth worrying. American tobacco company carries on secret research, want to find the method which removes 210 of polonium to this. But never succeeded, they conceal all the research, have been exposed in recent years.
210 of polonium is drama poisonous substance quality, 210 for a microgram of polonium can kill a person. However, 210 content of polonium in the cigarette is really too low, its toxicity is not worth worrying.
Why is the cigarette so fragrant? Apply fertilizer repeatedly, reduce the nitrogen content
How could contain 210 of polonium in the cigarette? They may be the phosphorus fertilizer constructed when come from planting the tobacco. Low in nitrogen of the tobacco, knows the comparison " fragrant " for the cigarette ,And through constructing the high phosphorus fertilizer repeatedly, can reduce the nitrogen content of the tobacco. So, should exert the high phosphorus fertilizer in a large amount while planting the tobacco. Contain micro- uranium 226 in the phosphorus fertilizer, uranium 226 decays and turns into 210 of polonium, 210 of polonium in the soil is absorbed by the root of the tobacco, collect in the tobacco leaf richly. While applying fertilizer, 210 of polonium falling on the tobacco leaf will be absorbed on the tobacco leaf surface too.
One and a half packs of cigarettes every day Make chests 300 times a year completely in other words
It is the radioactivity of 210 of polonium that is worth worrying about. What 210 of polonium is radiated is retarded ray, does not wear people's skin completely, if is outside the body, have not threatened the health. But the cigarette has been lighted, 210 of polonium is inletted with the smog into the lung, will be far from good. 210 of the polonium is deposited in lung cells, keep in touch with a distance of cell, the mental deficiency ray radiated can cause damaging to cells too, thus bring out cancer. If release cigarette of 1 and a half packs every day, will get off in one year, the radiation quantity received is to do X-ray chest 300 times completely.
Compared with other carcinogen in the cigarette, a factor not very important that 210 of polonium actually just causes lung cancer, probably only 1% of the lung cancer is caused by 210 of polonium, lead to the fact every year more than 10,000 people die. But people should be much better than carcinogen to the sense of fear of the radioactivity material. So contain radioactive material, a strong reason why the opium pipe gives up smoking that perhaps can become in the cigarette to advise. Should not smoke in the public occasion at least, that is not only poisoning but also throwing " bomb " away ,Because contain the radioactive material in the second hand smoke too.
