Is there a list of acceptable materials for LL radiation?
Is there a list of acceptable materials for LL radiation?
(OP)
Has anyone a list of acceptable materials such as;
Stainless Steel, elastomer's, motor's and lubricants
that are acceptable in LL radiation service?
What is considered LL radiation?
I've checked out nrc web pages and can't find anything
really outlined. A thread connection would be nice
if some has a reference for me.

there is no such thing as ll radiation. probably u r referring to radiation caused by low level activity sources. normally in radioactive service SS304L is normally used as vessel and piping moc.

If you are intending to sell to the Nuke Power industry, you need to set up a 10CFR50 Appendix B quality program and be set for a very stringent quality audit. Then, run the material through a test lab and see if it holds up. At that time you can offer it for sale.

For example elastomers increase hardness and decrease elongation depending of the composition.
if you make a more detailed question may be possible indicate to you radiation level.

This is a list taken from a nuclear industry design specification:-
Recommended Materials (with 'good' stability at ambient temperatures in air with irradiation levels of 100,000 Grays):
Polyurethane, SBR Butadiene styrene, Ethylene propylene, copolymer EPDM, Polychloroprene;
Polystyrene, Polyethylene, Hypalon, ABS, PVA, Polyamide, Nylon, Polycarbonate, Polyester (mineral or glass filled), Mylar (Melinex)
Epoxy and Phenolic Adhesives
Mineral Oils (aromatics are more resistant than aliphatics) NB Bearing manufacturers will supply bearings packed with special grease if requested.
DO NOT USE:-
Fluorocarbon, Butyl Rubber, Silicone rubber, Neoprene, Polypropylene, Phenolformaldehyde
Natural (animal, vegetable) Oils.
Hope that this helps
