Abundance. Same problem that we have with sugar. Tobacco was a luxury, so you couldn't smoke it all day every day. More exposure to carcinogens means more cancer.
And those fiberglass filters probably don't help, either.
Everybody always forgets or ignores something that changed in the environment after WW2. All the above ground nuclear weapon testing that was done by the US and other nuclear nations put a lot of long lasting radionuclides into the air, water and soil. Those radionuclides entered our bodies and food and water supply. Radioactive particles, especially in micro- and nano-forms will cause cancer in the body by long term, close range exposure. It's easy to blame tobacco and other carcinogens, but I guarantee you the radioactive contamination of everything is the likely cause of much of the cancers we see now. It's bad shit and we put it everywhere, including tobacco plants.
BTW, the cigarette filters are made of cellulose fibers not fiberglass.
In general bad things in the lungs are more harmful than in the gut. They can more easily enter the blood through the lungs, and dust collects so if radioactive it keeps exposing the lung cells to it.
Million percent. I was recently discussing this with someone, trying to make the point there have been hundreds if not thousands of nuclear blasts on this planet. Above ground, at ground, below ground... in water- sheeeeit.
The radioactive half life is only like 35 years, I thought.
The radioactive half life is only like 35 years, I thought.
That depends on the particular radionuclides that are created during the blast. Some radionuclides will have very short half lives while others will have much longer half lives. Also, half life means how much time must past for the radioactivity to reduce by half. That means that a 35 year half life would cut the radioactivity by half in 35 years and in another 35 years it's one quarter as radioactive as its initial radioactivity. A 35 years half life radionuclide would still be radioactive for a long time and, in close proximity to your soft tissues, the amount of radioactivity will fuck you up over the years.
Dose over time and proximity to the source determine what happens to your body. You can live unharmed with the very small amount of Americium-141 in your smoke detector that is on the ceiling in your home, but put that same amount of Americium-141 inside your body and you'll definitely get very sick and die very soon. These radionuclides, no matter how active they are, are inside us all and causing trouble for us. This is what makes them dangerous and the likely cause of many modern cancers. All other carcinogens only add to the problems here.
