WTF?
1. "Attaching", as you put it, is a chemical reaction, Not only is it not a given that it will react from its original state, but it will become neither less or more radioactive as it does so.
is there a more proper term?
I can float an iron needle on water right....
would stick to dust be better? carried by dust?
2. If it's a heavy metal, it ain't gonna float on dust. The nanoparticles you describe have just as much mass as the huge chunks, just less volume. If you drop a 40 lb chunk of lead and a 3 oz chunk of lead from a height, they'll both fall at the same rate. Gravitational pull is independent of size. Trade winds will not carry it anywhere.
point is regardless of the weight and yes it is heavy it can be carried on dust if the particles are small enough, in the range of nano.
put it this way...if the buoyancy of a chunk of dust is greater than the gravity acting against the particle and the dust it will float on the air. Thats not to say every particle of dust will have with it a particle of plutonium etc or be capable of floating it, but how many ways woud we like to slice this.
I'm not saying it won't find its way over here, but if the path is long enough, it'll be dispersed by the time it gets here. Remember, if the fuel is uranium, the fuel is nothing more than naturally occurring uranium that was concentrated in a centrifuge. If it's dispersed, well, that's how it was in nature in the first place.
well sorta kinda.... its not like they strip the top of a field to get it you know. most is mined.
3. It will NOT be peed out. It won't get that far into the body. As I said above, it is NOT water soluble. Anythiing that is peed is absorbed into the body (usually through digestion), collected from the cells, filtered through the kidneys, and passed out. That is impossible for things that are not water soluble. If any heavy metal isotopes are ingested, they will NOT be absorbed into the stomach lining in the first place and will be excreted out (to put it politely). In other words, no damage.
yup good cal I should have said shit out.
if you are claiming no damage that is not correct, there certainly is damage from any ionizing radiation in your body. the longer it stays in the body the more like you will get cancer the more dna get mutated. If it get caught on something on its way through then it can and does stay there for years nuking the person.
At Rocky Flats, we analyzed the four separate pathways that plutonium could enter the body - ingestion (as above, not a concern), inhalation, absorption (skin contact), and injection (entering through an open wound). Absorption was obviously not an issue since Pu is not water soluble. Injection was done by reducing sharp edges in the workplace. Inhalation was a serious concern and measures were taken to reduce it.
As I said above, this depends on what the isotopes are. I sure as hell hope they're not water soluble.
the problem is the size. submicron particles of any substance is well known to enter into the mitochondria simply due to its incredibly small size and has nothing to do with absorbtion.... if you are reading absorption as the same thing as "dissolving" or breaking down somehow. That is not necessary. I dont plan on looking up the precise label put in it though
