Re: Radon class demo

[Jjblute1@aol.com]

I may stand corrected, but heres my explaination...

It is not the radon itself that is posatively charged (it is an inert gas) 
but the radon daughter products (Pb Bi Po) that attach to charged particals 
in the air.  When you collect a "radon sample", you are not actually 
collecting radon as it is inert, but the daughter products that are produced 
by radon in the air.

The charged daughter products (or charged particals in the air that they are 
attached to, someone else may be able to elaborate) are attracted to TV and 
computer monitor screens.  This is why you can usually get a pretty hot swipe 
off of a computer screen that has been on for a while.
