Physical properties of irradiated polymers are subject to
variations due to: 1) Stress (residual and functional), 2)
Section thickness, 3) Molecular weight distribution, 4)
Morphology, 5) Moisture, 6) Environmental (oxygen
temperature) and must be tested in the specific application
under consideration
