Hi All,
I need to find a tungsten foundry or a source for tungsten sheet
to make some radiation shielding for a prototype PET scanner. The head
of the program has decided not to use lead and has asked me to design
and build the shielding. We want to use the tungsten alloy with the
highest density that is economically available. From my research so
far I believe we will be using one of the K18** alloy's but I'm not
sure if magnetism is an issue for us or not. The energy level we are
using is 511 KeV.
The problem that I am running into is that we only need a handful of
pieces and no one that I have talked to so far seems terribly
interested. I need 8 elliptical strips with a length of ~26" and a
width of 3.5" to 7.5", the thickness will be .25" for four of the
pieces and .094" for the remaining four pieces.
I realize that most tungsten parts are formed by powder metallurgy
and that would probably be best, but, we do have a high-quality water
jet available so if I have no other options and I can find sheet
material we can make the parts here.
Any help or suggestions you can give me on a supplier or material
selection would be greatly appeciated.
Thank you in advance, Dave Wilson
