A Study of the Composite Character of the ESR Spectrum of Alanine

摘要

Both L and DL-alanine ESR powder spectra have been studied in the dose range of 1-10~6 Gy. By using Maximum Likelihood Common Factor Analysis (MLCFA), it has been demonstrated that the ESR spectrum of L-alanine is at least 3-fold composite over the whole dose range considered. For DL-alanine, in certain dose ranges only two ESR components could be detected. Possible consequences for the application and optimization of alanine dosimetry are discussed.
