Lyoluminescence and ESR measurements on alanine and sucrose dosimeters
TLDR
A lyoluminescence reader was constructed and the response of irradiated dl -alanine and sucrose was investigated as a function of the sensitizer concentration, solution pH, mass of material and absorbed dose.About:

EPR and UV spectral study of gamma-irradiated white and burned sugar, fructose and glucose.
TL;DR: It is shown that gamma-irradiation of solid samples of white sugar and fructose yields stable EPR spectra whereas glucose signal remains time-dependent even 11 months later, and suggests sugar as the best, universal material for EPR- and/or UV-dosimetry.

ESR dating of a toxodon tooth from a Brazilian karstic cave
TL;DR: A pre-molar of a Toxodon platensis (sp), a large mammal that inhabited the forests of Southeast Brazil during quaternary times, was dated by electron spin resonance (ESR) and the age obtained is (6.7+/-1.3) ky BP for dentine and (5.0+/-2.6) kY BP for enamel.

Applications of EPR in radiation research
Anders Lund,Masaru Shiotani +1 more
TL;DR: In this paper, the ESR spectrum of fraction 9.10d was analyzed and it was shown that the spin-trapped radical does not originate from the free radicals produced by H abstraction from the 1′-, 2′or 3′-positions on the sugar moiety.

Electron paramagnetic resonance investigation of sucrose irradiated with heavy ions.
Kouichi Nakagawa,Teiji Nishio +1 more
TL;DR: The results of γ irradiation of deuterated sucrose suggest that one of the persistent radicals is a carbon-centered radical, which implies that LET at a certain dose can be determined by the spin concentration.

TL;DR: The results are presented of an electron magnetic resonance analysis at 110 K of radiation-induced defects in sucrose single crystals X-irradiated at room temperature, yielding a total of nine (1)H hyperfine coupling tensors assigned to three different radical species.

The use of alanine as a solid dosimeter.
TL;DR: Electron spin resonance has been found to be a satisfactory technique for the calibration and measurement of radiation doses by means of alpha - alanine dosimeters, and dosimeters from alpha -alanine were find to be stable, having about 5% decay after 90 days.

Lyoluminescence dosimetry part II. State-of-the-art.
TL;DR: The survey of dosimetric properties of mannose and glutamine includes response to X- and gamma-rays, electrons, heavy charged particles and to neutrons, and current applications of lyoluminescence dosimetry include radiotherapy, radiation processing of foods and sterilization of medical products.
