DOI 10.1063/5.0193755
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

Results of studying impact of gamma-rays on adsorptive properties of silicon dioxide (SiO2) of various types are presented in this research paper.Temperature and dose dependencies of adsorption of oxygen and hydrogen on silicon dioxide samples undergone preliminary heat treatment within a temperature range 200-800°С were investigated.Manometric methods, infrared, electron paramagnetic resonance spectrometric methods were used.As a result the following was established: adsorption centers are appearing under exposure to radiation either having paramagnetic properties or without them.Dependence of accumulation of adsorption centers on preliminary annealing temperature and radiation dosage is observed [1-3].
