  • ...Recently it has been reported that sugar is one of the best dosimetric material for use in emergency dosimetry (Azorin et al., 1989; D’Errico et al., 1996; Generalova et al., 1993; Gutierrez and Azorin, 1993; Haldar et al., 1997; Nakajima, 1988; Trivedi and Greenstock, 1993; Tchen et al., 1993; Wieser et al, 1994)....

TL;DR: In this article, the authors used MgB4O7:Mn2+ phosphor material to synthesize Lyoluminescence (LL) for radiation dosimetry of high-energy radiations.
Abstract: Lyoluminescence (LL) is a good technique for radiation dosimetry of high-energy radiations. Dosimetry of γ rays from 60Co radioactive source has been done using MgB4O7:Mn2+ phosphor material. It was synthesized by simple solid state diffusion method. The material shows good linear LL response with the γ rays for the dose rage of 10 Gy–10 kGy. The studies have also been done for different particle sizes (250–45 µm) and particles having average size ~85 µm were found to be the most suitable for this dosimetry. Effect of solvent pH on LL and fading on storage has also been studied.

TL;DR: Practical considerations of sample size, microwave power, modulation amplitude, EPR spectrum and signal stability are discussed, and particularly the EPR measurement methods of sucrose are introduced.
Abstract: Sucrose is a convenient, common, tissue-equivalent material suitable for electron paramagnetic resonance (EPR) dosimetry of ionising radiation. A number of publications have reported on the dosimetric properties of sucrose and their use in radiation accident dose reconstruction. However, previous studies did not include specially the description of measurement methods of sucrose by EPR. The aim of this work is to introduce particularly the EPR measurement methods of sucrose. In this regard, practical considerations of sample size, microwave power, modulation amplitude, EPR spectrum and signal stability are discussed.

TL;DR: Various experimental factors which could affect the dose measurements using lyoluminescence are discussed, including the energy response for X-rays, and some preliminary information on the response of saccharides to fast neutrons is also included.
Abstract: Lyoluminescent properties of mannose, glucose monohydrate, sucrose and trehalose dihydrate were investigated from the point of view of suitability as dosimetric materials in a new system of solid state dosimetry. Distilled water was used as a solvent. With a reader equipped with an uncooled PM tube it was possible to measure doses of X- and gamma -rays in the range from a few rad to about 100 krad. Various experimental factors which could affect the dose measurements using lyoluminescence are discussed, including the energy response for X-rays. Some preliminary information on the response of saccharides to fast neutrons is also included.
