タバコ会社は,タバコに放射性物質が含まれることを40年間隠蔽していました

「Tobacco companies knew that cigarettes contained a radioactive substance called polonium-210, but hid that knowledge from the public for over four decades, a new study of historical documents revealed.
Scientists from the University of California, Los Angeles, reviewed 27 previously unanalyzed documents and found that tobacco companies knew about the radioactive content of cigarettes as early as 1959. The companies studied the polonium throughout the 1960s, knew that it caused ”cancerous growths” in the lungs of smokers, and even calculated how much radiation a regular smoker would ingest over 20 years. Then, they kept that data secret.
Hrayr Karagueuzian, the study's lead author, said the companies' level of deception surprised him.
”They not only knew of the presence of polonium, but also of its potential to cause cancer,” he said.
Karagueuzian and his team replicated the calculations that tobacco company scientists described in these documents and found that the levels of radiation in cigarettes would account for up to 138 deaths for every 1,000 smokers over a period of 25 years.
The study published online in the journal Nicotine and Tobacco Research.」
また,タバコ会社は,ポロニウムー210を除去するacid washingは,ニコチンラッシュを損なうとのことで,採用されなかったことも明らかになりました.
「Officially, tobacco companies said acid washing would cost too much and might have a negative impact on tobacco farmers and on the environment. But Karagueuzian said the documents his team reviewed revealed another reason why the industry avoided acid washing for tobacco leaves: the process would alter the nicotine in the plants and make it less able to deliver the ”instant nicotine rush” smokers craved.」

肺のホットスポットに集まったタバコの中の放射性粒子により,今後25年で死亡する可能性のある人は,喫煙者1000人のうち120~138人とのことです.
日本のタバコ会社の内部文書は,米国のタバコ会社の内部文書とは異なり,公開されていないので,同様の認識だったかはわかりませんが,日本のタバコ会社は米国のタバコ会社と同様の技術レベルにあったことは事実です.
なお,明日10月12日午後2時から東京高裁でタバコ訴訟の期日があります.タバコ訴訟は,明日で,争点整理,時系列表等がほぼ完成になりますので,終結時期もちかいでしょう.
