ERT SERIESMEDIUM DUTYRADIATION RESISTANT
PHYSICAL PROPERTIES
EFFECT OF RADIATION ON PHYSICAL PROPERTIESThe effects of radiation (neutron and gamma particles) on RYTON® R-4 materialhave been studied. Since Ryton®, as an engineering plastic, may fill applicationsin nuclear installations these effects are important. The test results show noeffects on physical properties by these relatively high exposures to gamma andneutron radiation. There is no indication from these data of crosslinking ordegradation of the RYTON® R-4 material.
