Abstract
The results of the investigation of the effect of mobile phone radiation on the formation of electron paramagnetic resonance (EPR) spectra and electromagnetic noise on the example of measurements of dental enamel samples for the low dose range are presented. To this end, spectra of irradiated dental samples were obtained. The spectra of ten samples irradiated in nominal doses of 0, 100, 200, 300 and 500 mGy in pairs were registered at different times with and without a mobile phone. The mobile phone was located near the resonator of the EPR spectrometer. Specially software was used to extract the radiation-induced signal (RIS) from the full EPR spectrum and determine its intensity. As mentioned above to study the effect of the mobile phone signal on the EPR signal in this study, the radiation signal (RIS) (standard deviation (SD)) will be estimated by the background signal and the residual amount. These parameters were obtained for single measurements and, on average, for four repeated measurements.
