NEW POSSIBILITY FOR ESTIMATION OF RADIATI ON-DOSES BY ELECTRON-SPIN-RESONANCE TECHNIQUES

Spin-lattice relaxation rates of radiation induced and background cent ers in dental enamel have been investigated by electron spin resonance techniques. It has been found that these centers differ in the value of the saturation half-power and the saturation process. Based on thes e experimental results a new approach to discrimination of the radiati on induced signal from the total ESR spectrum of dental enamel is prop osed. Comparison of the current methods of radiation dose estimation b y the ESR analysis has been performed using the new approach.
