Abstract: After being irradiated by X-rays or γ-ray, new free radicals would produce within the fingernails. Using electron paramagnetic resonance (EPR) technique, signals representing free radicals can be detected and form an electron paramagnetic resonance spectroscopy. EPR signal formation, method of abtaining radiation-induced signal, signal stability and its affecting factors were discussed in this paper.

Key words: EPR signal, fingernail, stability
