For example, if a survivor of a nuclear bombing came to your fallout shelter or basement with radioactive fallout all over him or her, and you thoroughly washed all of the dust off of him or her, won't his or her own exposure to the fallout have particles radiating out of his body?

If not, then what exactly is radiation sickness -- is it the inhaling or injesting of the dust?

I just don't see how the dust can radiate into our bodies, but human bodies cannot -- is it not the chemical reactions of raioactive material in contact with non-radioactive material that causes radiation?

And even if you kept your distance from him or her, wouldn't the radiation radiate from him, through the air, to you and everywhere else like a chain reaction?

is it when you do:

f(f^-1(1))

or

i know that both would work but what is know as "composition"??

Tape will not work as an electrical insulator on the model i'm building.
Were can I find, or what can be used as a "non" - conductive
electrical insulation to cover the very small wires in this model. It would be easier for my application if it was in a liquid form, similar to a heavy paint that could be applied with a small brush.
