Radiation Resistant Lubricating Oil and Greases
The world's highest radiation-resistant lubricants supporting advanced radiation sciences and decommissioning
MORESCO-HIRADs have been supporting lubrication of moving equipment in severe, high radiation environments, such as worldwide accelerators, radiation therapies, irradiation sterilizations, nuclear fusions, nuclear power plants, nuclear fuel reprocessing, and decommissioning with their outstanding radiation resistance, while contributing significantly to stable operations and longer maintenance cycles of equipment and facilities.
【Note】 Remarkable findings through irradiation to the radiation resistant greases/oils have been published as some literature in a joint academic studies with the European Accelerator Project.
