A new resonator for X-band in vivo EPR nail dosimetry, the dielectric-backed aperture resonator (DAR), is developed based on rectangular TE102 geometry. This novel geometry for surface spectroscopy improves at least a factor of 20 compared to a tradi

Exposure of finger- and toe-nails to ionizing radiation generates an Electron Paramagnetic Resonance (EPR) signal whose intensity is dose dependent and stable at room temperature for several days. The dependency of the radiation-induced signal (RIS)

Radical pairs produced by the photolysis of 4-bromo-2,6-di-tert-butylphenol single crystals doped with 2,6-di-tert-butyl-p-quinone are studied by EPR spectroscopy. The mechanism of radical pair generation changes from hydrogen-atom transfer to electr

We have investigated the temperature and time dependences of the D -value and the intensity of mechanochemically generated radical pairs in order to establish the nature of these radical products. The method of synthesis of those pairs, based on the

The pulse action of elastic waves on polycrystalline mixtures of 3,6-di-tert-butylcatechol and 3,6-di-tert-butyl-o-benzoquinone produces radical pairs stable at room temperature, and the addition of polycrystalline sulfur considerably increases their
