Configured to provide gamma dose rates over four orders of magnitude, the gamma irradiation facilities have been used extensively for food irradiation studies, developing optimized radiation doses for medical product sterilization, and radiation effects evaluations on electronic components and other materials such as optical components (mirrors, lenses and windows) for space applications. Biomedical studies have focused on radiation induced cross-linked polymers for medical applications in tissue engineering and improved prostheses. Other studies include radiation effects on plastics used in the treatment of cancer.

Facilities (from highest to lowest dose rates)

Quality Assurance

All facilities are assessed for accuracy and precision using traceable technologies. Accurate radiation exposure is assured by using aminotriphenylmethan / optichromic dosimetry (Far West Technology) and alanine/electron paramagnetic resonance (EPR) (Bruker) dosimetry systems. A Quality Assurance Program meeting the requirements of the Nuclear Regulatory Commission regulation (10.CFR.Part 50 Appendix B) that provides for the performance and maintenance of gamma dosimetry calibration traceable to the National Institute of Standards and Technology.
