Determination of the crystalline fraction in bone and other mineralizing tissues within the histochemical range by electron spin resonance spectroscopy.

The theoretical principle based on the application of electron spin resonance technique for calculation of the crystallinity coefficient of mineralized tissues is presented. The method is based on measurements of radiation-induced stable paramagnetic centres derived from the crystalline fraction of tissue mineral. The high sensitivity and accuracy of the discussed method allows to apply it in the histochemical range.
