BUCHANAN Terminal Blocks Note: All part numbers are RoHS Compliant. ERT Series, Medium Duty Radiation Resistant Physical Properties Effect of Radiation on Physical Properties The effects of radiation (neutron and gamma particles) on RYTON R-4 material have been studied. Since RYTON, as an engineering plastic, may fill applications in nuclear installations these effects are important. The test results show no effects on physical properties by these relatively high exposures to gamma and neutron radiation. There is no indication from these data of crosslinking or degradation of the RYTON R-4 material. Note: Determination of the suitability of the ERT Series Blocks for particular applications rests solely with customers.
