I've heard of obviously vacuum packing something  , anti-mate ( dog repellent) coffee which is probably useless.

« on: 26/11/2011 12:04:02 »

Hi I just joined , so take it easy on me ! haha

Anyway i have a few odd questions about Lead that are very important to me.

1. how dense is lead?
2. how thick would a sheet of lead be to block gamma / x ray ray's?
3. how hard would it be to obtain Lead customised to a specific area/dimension.
4. is their different grades of Lead

Thanks , please help!
