Purpose: Investigation of paramagnetic properties of radiation-induced centers that occur when hair samples are irradiated with ionizing radiation, depending on the color of the sample. Material and methods: A Bruker Elexsys E580 electron paramagnetic resonance spectrometer was used. To improve the signal-to-noise ratio, the spectrum was recorded with three accumulations with a constant scan time equal to one minute. Measurements were made using a highly sensitive rectangular Bruker SuperHighQ resonator. For irradiation of samples, the linear electron accelerator UELR-10-10С2 of the innovation and implementation center for radiation sterilization of the Urals Federal University (Institute of Physics and technology) was used. Results: Research of the EPR signal parameters of the melanin in hair samples of different colors (black, brown, red and gray with different degrees of pigmentation) showed that the intensity of the EPR signal varies depending on the hair color. The higher the radiation sensitivity of the hair, the lighter the color of the hair. The melanin signal, which is the background for the radiation-induced signal, increases with increasing intensity of hair color. © 2022 State Research Center, Burnasyan Federal Medical Biophysical Center of Federal Medical Biological Agency.
