It is found that the response curve at low doses has a concavity directed opposite to that of quartz grains extracted from archaeological potteries. To explain this behavior a model is proposed here based on oxygen vacancies and [AlO4/h](0) centers. The experimentally observed ESR intensity of E-I'-centers as a function of radiation dose can also be explained by this model.123-132engGamma irradiationOxygenQuartzSedimentsThermoluminescenceVacanciesArtigo10.1080/10420159808220028WOS:000165533100010Acesso restrito2-s2.0-00316403458507741729691974
