Resumo
Measurements of free radical densities in sugar by electron spin resonance (ESR) constitute a useful method for
determining the dose received in the case of accidental irradiation because this material retains its radiation history. The
aim of this work is to establish methods for practical dose assessment of people involved in ionising irradiation
accidents, using two types of sugar: sucrose and dextrose. In this regard, practical considerations of sample preparation,
grain size, ESR spectrum and spurious mechanical-induced ESR signal are discussed. Also presented are results for
signal reproducibility, radiation response, signal stability and low-dose values. Studies on irradiated samples were
carried out to explain the complex spectra derived from different paramagnetic species.
