RE: Looking for vendor-polyethylene pig for neutron source

Mr Wickland,



Try Thermo Electron Corporation http://www.neutron-shielding.com/

I have used their products for applications requiring neutron shielding

on many occasions. [5% Boron-Polyethylene excellent attenuation of thermal 

neutrons and significant reduction of capture-gamma dose].

Subject: Looking for vendor-polyethylene pig for neutron source





We are in the process of leasing a 1 mCi Cf-252 sealed neutron source from ORNL under its university loan program. At first we thought that we would be allowed to keep the lead-lined polyethylene pig the source ships in, but now we're told we must return it as soon as we receive the source.



Does anyone know of a vendor who carries such a pig ready-made? Or are we going to have to make our own?



We're also looking for a source of polyethylene bricks, or are these also a make-it-yourself item?



Thanks for any info you can provide.
