Ashland RAD-SURE

At blood centers, Ashland’s Rad-Sure indicators provide positive visual verification of the irradiated status of blood units. In addition, the Dose-Map calibration system validates the performance of blood irradiators.

Outdoors, Ashland reduces the need for pesticides with the Sterin system for the Sterile Insect Technology (SIT) program. Sterin irradiation indicators support SIT, an environmentally friendly method of controlling pests by causing sterility through irradiation during their pupal stage. The indicators help ensure verification of irradiation.
