Material suitability:

some polymer materials are sensitive to radiation processing.

here a small list of some materials:

Material	Tolerance Level kGy	Remarks
ABS	1000	avoid high doses on high impact grades
PET, PETG	1000	retains clarity. Drying is essential
Cellulosics:
Ester, Ether	100
Paper, Card, Corrugated, Fibers	100-200	discoloration, embrittlement
Cellulose Acetate, Butyrate, Propionate	100
Fluorpolymers:
