Neutron damage studies of organic materials with NQR spectroscopy
- Univ. of Florida, Gainesville (United States)
Noninvasive techniques for the evaluation of radiation damage to materials exposed to neutrons provide valuable methods for monitoring neutron-induced radiation damage. Radiation damage to many organic materials is difficult to monitor without destructive testing. The authors present a new technique for the evaluation of neutron-induced radiation damage based on nuclear quadrupole resonance (NQR) techniques. This demonstrates the NQR response to neutron damage in two organic materials and provides quantitative estimates of microdosimetry and damage sites associated with neutron-induced damage in these materials. They have used {sup 14}N as a probe nucleus to detect molecular bonding changes induced by neutron irradiation. For these studies, two simple, nitrogen containing, organic materials known to provide strong NQR signals were chosen: urea (CO(NH{sub 2}){sub 2}) and thiourea (CS(NH{sub 2}){sub 2}).
