“…[1][2][3][4]6 Environmental/construction objects are abundant, present zero background signal, allow doses of the order of mGy to be detected, show stable signal over time, and can easily be collected and processed in a short time. 1,2,4 They have also been retrospectively tested in several sites 8,9 affected by past nuclear accidents and therefore are characterized by well-defined preparation and measurement protocols. Nevertheless, they only provide local, environmental dose information so that personal doses cannot easily be calculated.…”

The rapid assessment of radiation dose to members of the public exposed to significant levels of ionizing radiation during a radiological incident presents a significant difficulty in the absence of planned radiation monitoring. However, within most personal electronic devices components such as resistors with alumina substrates can be found that have potentially suitable properties as solid state dosimeters using luminescence measurement techniques. The suitability of several types of ceramic-based components (e.g., resonators, inductors and resistors) has been previously examined using optically stimulated luminescence (OSL) and thermoluminescence (TL) techniques to establish their basic characteristics for the retrospective determination of absorbed dose. In this paper, we present results obtained with aluminum oxide surface mount resistors extracted from mobile phones that further extend this work. Very encouraging results have been obtained related to the measurement of luminescence sensitivity, dose response, reusability, limit of detection, signal reproducibility and known-dose recovery. However, the alumina exhibits a rapid loss of the latent luminescence signal with time following irradiation attributed to athermal (or anomalous) fading. The issues related to obtaining a reliable correction protocol for this loss and the detailed examinations required of the fading behavior are discussed.

“…Thus the total dose, DL = A(Dα + Dß + Dry + Dc) where D is the cumulative transient gamma dose received by the ceramic sample due to artificial radioisotopes, A is the sample age in years; Dα , Do, D., and Dc are effective annual alpha, beta, gamma, and cosmic ray doses, respectively, due to natural sources of radioactivity. Further details are reviewed by Bailiff [24] and Høtter-Jensen et al [25].…”

Luminescence signals measured from minerals within bricks or ceramic samples can provide information about the absorbed radiation dose. This feature has for several years been used in dating archaeological and geological samples and recently luminescence techniques have been intensively used for retrospective assessment of accident doses received by the population after a nuclear accident. The development of new luminescence techniques after the Chernobyl accident has considerably improved the sensitivity and precision in the evaluation of accident doses. This paper reviews the development work, especially on optically stimulated luminescence methods for retrospective assessment of accident doses carried out at Risø National Laboratory in collaboration with the University of Helsinki as part of a joint European Union research project. We demonstrate that doses lower than 100 mGy can be measured from extracted brick quartz with a precision in the order of 1% using newly developed optically stimulated luminescence dose evaluation protocols.

“…Accidental dosimetry also includes the determination of radiation doses during events such as nuclear weapons explosions, nuclear reactor accidents or other incidences of unintended radiation release [1,3,4]. Some materials proposed for the mentioned application are quartz, NaCl, ceramic materials, calcium, silicate bricks, red bricks, and other building materials which are laid in homes, offices or schools, hence, they can act as thermoluminescence dosimetric materials in case of radiological accident [1,3,4,5,6,7,8]. A few of these materials are used in TL dating as well, an useful technique to determine the dose absorbed by natural materials resulting from exposure to naturally occurring radio-nuclides in the environment [9].…”

Study of the Thermoluminescent Characteristics of Ceramic Roof Tiles Exposed to Beta Radiation

In this work, thermoluminescence (TL) characteristics of roof tile ceramic samples previously exposed to beta radiation are reported for the very first time. TL measurements were carried out using powdered samples obtained by the the fine-grained method, with grain size ranged from 300 nm to 5 μm. Characteristic thermoluminescence glow curves showed a complex structure with a dosimetric maximum located at ~ 200 °C. TL response of roof tile samples increases as the radiation dose increases in the 25 Gy to 1.6 kGy range. One response showed a linear behaviour, with no evidence of saturation within the dose interval investigated. The entire TL glow curve exhibited a remarkable reusability during 10 consecutive irradiation-TL readout cycles. The total TL signal showed a very low fading and remained almost constant after 3 h of irradiation and the corresponding TL readout. TL dosimetry features of powdered roof tile place it as a promising material in retrospective dosimetry as well as in possible TL dating applications.
