摘要

本研究的目标是对几种类型的 TL 和 OSL 探测器进行初步筛选调查，旨在寻找存在剂量率效应的迹象。研究针对十种不同的材料进行：LiF:Mg,Ti；LiF:Mg,Cu,P；CaF2:Dy；Al-P 玻璃；YAP:Mn；CaSO4:Dy；Al2O3:C；BeO；MgB4O7:Ce.Li 和石英。伽马射线剂量率从 0.1 mGy/h 到 90 Gy/h。没有发现任何材料有明显的剂量率效应。在两种情况下（MgB4O7:Ce,Li 和 BeO）观察到了一些不规则的反应，这需要进一步研究，但很可能不是剂量率影响造成的。

Searching for TL/OSL dose rate effects in various luminescent materials

The goal of the present work was to conduct an initial screening survey of several types of TL and OSL detectors, aimed at searching for the indication of the presence of dose rate effects. The study has been performed on ten different materials: LiF:Mg,Ti; LiF:Mg,Cu,P; CaF₂:Dy; Al–P glass; YAP:Mn; CaSO₄:Dy; Al₂O₃:C; BeO; MgB₄O₇:Ce.Li and quartz. Gamma-ray dose rates ranged from 0.1 mGy/h to 90 Gy/h. No clear evidence of dose rate effects was found for any material. In two cases (MgB₄O₇:Ce,Li and BeO) some irregularities of the response were observed, which require further investigations but most probably they are not attributable to the dose rate influence.

期刊介绍： The journal seeks to publish papers that present advances in the following areas: spontaneous and stimulated luminescence (including scintillating materials, thermoluminescence, and optically stimulated luminescence); electron spin resonance of natural and synthetic materials; the physics, design and performance of radiation measurements (including computational modelling such as electronic transport simulations); the novel basic aspects of radiation measurement in medical physics. Studies of energy-transfer phenomena, track physics and microdosimetry are also of interest to the journal. Applications relevant to the journal, particularly where they present novel detection techniques, novel analytical approaches or novel materials, include: personal dosimetry (including dosimetric quantities, active/electronic and passive monitoring techniques for photon, neutron and charged-particle exposures); environmental dosimetry (including methodological advances and predictive models related to radon, but generally excluding local survey results of radon where the main aim is to establish the radiation risk to populations); cosmic and high-energy radiation measurements (including dosimetry, space radiation effects, and single event upsets); dosimetry-based archaeological and Quaternary dating; dosimetry-based approaches to thermochronometry; accident and retrospective dosimetry (including activation detectors), and dosimetry and measurements related to medical applications.
