i did. it says "unable to connect: null." how did u know i used to be ezra_maliki?

 

you can get it at messenger.yahoo.com

I knew you are named ezra by using the built-in bot on the chatroom that google searches for you. I just typed in "google yourdadonapogostick".

i wonder how it connected them.

Obviously the bot is already on the internet, so it probaby did a google search like some metasearches can do (remotely).

yay, i figured it out.

 

i think it would be safer if i change from using my upstairs to using my garage.

NO! NO ALUMINUM! Aluminum, when hit with radiation, likes to shoot off neutrons (I think... I'll check in a minute) and neutron radiation is quite dangerous. You better get a Dosimeter and a charger off of eBay (preferably one with a low scale and one with a high scale) just to be safe. No, not a geiger counter, dosimeters will measure the amount of radiation you are exposed to over an extended period of time.

 

~10 keV X-rays aren't going to eject neutrons from Al. The energy required to eject a neutron from Al-27 is about 13 MeV. You are probably thinking of alpha scattering experiments.

 

_{edit: used "alpha" instead of the tex. It worked in preview mode, though...}

Maybe I was thinking of alpha radiation hitting aluminum... sorry.

In the early 70's, wasn't NASA planning on using aluminum to send astronauts to Mars?

Does he mean an aluminum space ship? Or aluminum propulsion????

in the ship. for the hull. they used it on Apollo, cuz it aint that heavy.

So using it for a proposed Mars trip would be

a) revolutionary

b) obvious

but bad cuz radiation. read the whole thread.

If you want lead glass like you see in a xray room your looking down the barrel of a grand. If you plan on buying an old xray machine don't, they are usualy from tight dentists who run then into the ground and only buy new when they get caught with dangerous equipment. My company was asked to service equipment for a dentist that was untested and so old it was ilegal. Don't bother you'll hurt your self or someone else. The higher the kv the more penitrating the radiation. You will not know this with an untested old machine. I don't want to spoil your fun but
