Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

It is known from the world literature that for EPR spectrometry for emergency dosimetry, where doses from 0.5 Gy and higher are used, the quality and reliability of calculating the experimental dose depends on the parameters of recording spectra (accumulation time, microwave power). This article describes the results of the development and application of a method for optimizing the parameter of recording EPR spectra on human tooth enamel, such as microwave power, but in the range of emergency radiation doses (from 1 Gy to 5 Gy), under conditions of a local radiation incident based on a biodosimetric laboratory. The results showed that the obtained experimental microwave power value of 5 MW is the most effective parameter for improving the quality of EPR spectra of human tooth enamel for a range of emergency radiation doses, even taking into account different types of spectrometers on which measurements are carried out. Optimization of the parameter for recording EPR spectra, in particular microwave power, improves the quality of the obtained spectra for the range of emergency radiation doses, even taking into account different types of spectrometers on which measurements are carried out.
