Nuclear quadrupole resonance (N.Q.R) frequencies are influenced by the symmetry of the charge distribution of a compound around the site of interest. Damage by ionizing radiation causes changes in this charge symmetry which can be detected by standard pulsed N.Q.R. methods. Previous work done on various chlorates of {sup 35}Cl at room temperature (Vargas et al., 1978) shows a linear effect between absorbed gammadose and the N.Q.R. frequency shift and line broadening. This paper reviews the theory of N.Q.R. and details our experimental apparatus. The accumulated data on {sup 14}N-containing compounds, both irradiated and nonirradiated, is discussed. The long term goal of this research is to choose an appropriate organic compound to duplicate the effects of radiation on human tissue. Under such conditions, we may be able to extend this work to provide a mixed radiation field (gamma and neutron) dosimeter which does not require knowing quality factors or energy fluences.
