“…Radiophotoluminescent (RPL) glass dosimeters [1] using silver-activated phosphate glass have been widely used for personal, environmental and clinical dosimetry, along with optically stimulated luminescence (OSL) dosimeters [2] and thermoluminescent (TL) dosimeters [3,4]. In particular, the RPL dosimeter has been recognised as possessing desirable characteristics such as high spatial resolution, non-destructive readout capabilities, a long-term stability against fading, a wide dynamic range and uniformity/batch homogeneity [5].…”

We report novel disk-type X-ray two-dimensional (2-D) imaging detectors utilising Ag-doped phosphate glass and lithium fluoride (LiF) thin films based on the radiophotoluminescence (RPL) and photoluminescence (PL) phenomena, respectively. The accumulated X-ray doses written in the form of atomic-scale Ag-related luminescent centres in Ag-doped glass and F-aggregated centres in LiF thin films were rapidly reconstructed as a dose distribution using a homemade readout system. The 2-D images reconstructed from the RPL and PL detectors are compared with that from the optically stimulated luminescence (OSL) detector. In addition, the optical and dosimetric characteristics of LiF thin films are investigated and evaluated. The possibilities of dose distributions with a high spatial resolution on the order of microns over large areas, a wide dynamic range covering 11 orders of magnitude and a non-destructive readout are successfully demonstrated by combining the Ag-doped glass with LiF thin films.

"This paper is a translation from the Japanese (Jpn. J. Radiat. Manag., Vol 15, 40-45, 2016)" Radiophotoluminescence (RPL) photography has been proposed for the measurement of the spatial dose distribution of high radiation fields. A pulsed UV-LED illuminator was prepared as an excitation light source for the RPL photography. The fluorescence image of RPL material was observed by a gated intensified CCD camera. In a preliminary experiment, several tens of spherical RPL detectors were placed near an intense 60 Co source. The pulsed UV-LED illuminator and the gated intensified camera were pulse-operated to obtain the RPL photograph of the ball-shaped RPL detectors. The spatial dose distribution was calculated from the brightness of obtained RPL images.

“…Other passive dosimeters based on the optically stimulated luminescence (OSL) [5], thermoluminescence (TL) [6] and photoluminescence (PL) [7] phenomena have been widely used for personal and clinical dosimetry and also used as a tool for micro radiography [8], proton beam diagnostics [9], heavy charged particle spectroscopy [10] and radionuclide imaging spectroscopy [11]. Although these types of passive luminescent dosimeters have each advantages and disadvantages, however, there have been a few 3 detectors capable of accumulating three-dimensional (3D) images over large areas and reconstructing dose distributions within several minutes.…”

Ag-activated phosphate glass based on the radiophotoluminescence (RPL) phenomenon has been used as the most commonly known RPL material and as an accumulated-type passive detector. In this work, the transient-state evaluation of the dose distributions achieved by X-and gamma-ray irradiations within the Ag-activated phosphate glass was performed using a time-resolved technique for the first time. Specifically, the blue RPL intensity ascribed to the electron-trapped Ag 0 centres as a function of the depth at the vicinity of the surface was investigated for different types of radiation and a wide range of energies. In addition, the dose distributions at each layer within the glass confirmed by the time-resolved measurement were compared with those reconstructed by a disk-type transparent glass detector based on the blue RPL with a diameter of 100 mm.
