IOTECH was a subsidiary company of CH2M HILL INC. created to provide a commercial entry in the product irradiation field. Its initial target was to sanitize packaged medical products, with food products as a targeted process in the future.

The process utilized by IOTECH involved the use of Cesium-137 which was stored in canisters. A great deal of money was invested in IOTECH on the strength of what was known about irradiation technology at that time. Unfortunately, canisters holding the critical component Cesium-137 had been found leaking in other user facilities and the U. S. Government stepped in to stop all operations using these canisters in their processing. This dealt a death blow to the IOTECH operation and it was forced to cease functioning.
