do you accuse ecologists of going back to school? Do you think it's the green people who smoke?
because they can't compare 1 and 1000?
I thought that with all the messages I had left on radioactivity, you had at least read a few!
the radioactivity of a man, pfffff ..... either, according to the WHO standards recently accepted with the CEA, but certainly not in the middle ages ... but let's move on!
there is a huge difference between an alpha, beta and gamma ray!
you did not know ? don't you remember high school class "an alpha ray is stopped by a sheet of paper"?
yes but our lungs are not sheets of paper, and all the particles + fine that the micron pass directly into the blood ... they are transported and are accumulated like all heavy metals in the heart and the brain. as soon as they are in the blood, they radiate everything around!
understand ? that is to say that it necrosis, carcinogenesis, mutagenesis etc ... by force, several years later it is the declared cancer which metastasized where are the heavy metals ... and it is transmitted from generation to generation! what the hell is that ... birth defects? my eye.
then it is sure that tobacco will be carcinogenic!
what catches up with a previous discussion I don't know if you remember, who tried to differentiate cancers due to tobacco and cancers due to radioactive elements (radio-nuclides) inhaled.
short .... you mean numbers I guess, so what is a simple, average irradiation: the particle in the lung that irradiates and kills everything around it, is reported relative to its size to the mass of the lung! therefore specialists in quantitative figures conclude: this is negligible!
but the qualitative ones conclude: it kills all around, and it accumulates.
so I laugh when we talk about radioactivity from the sea!
I hope someone understands out of pity; if you have not understood the nuclear lobby is causing trouble with the figures to say that it is negligible, by comparing the "natural" radioactivity of a soil in GAMMA rays in the Vosges or Brittany, or that of the sea or humans (which means NOTHING) with artificial radioactivity ALPHA.
a Bq = 1 disintegration ... whether beta or alpha it's the same isn't it? Gamma waves cannot be measured in Bq I think ...
Weren't there lessons on radioactivity at your school?
I have however put the links for ages, it doesn't surprise me that you cry when you hear me, if you still haven't understood ...
if you don't read it, AT LEAST read the page titles! -)

to say that you almost closed this subject it bores me ...
Well, anyway we knew that cigarettes were carcinogenic, ... but without knowing why!
