“…The EURADOS dataset consists of measurements made with multiple types thermoluminescent dosimeters (TLDs), radiophotoluminescent dosimeters (RPLs), and optically stimulated luminescent dosimeters (OSLDs) of doses delivered by a Saturne 43 linac (GE Medical Systems, USA). The calibration procedure for the various types of dosimeters is described by Knežević et al . Doses were measured at various locations inside a 30 × 30 × 60 cm 3 water phantom.…”

The purpose of this study is(was) to investigate the shielding ratio of 1 ㎜Pb and the off axis ratio outside the field edge at depth of 1 ㎝ from a phantom surface for 6 MV photon beam. A dose of 180 cGy was delivered to a depth of 10 ㎝ for a 10×10 ㎠ and 15×15 ㎠ field in the SAD technique. The off axis ratio was calculated by measuring the dose of optically stimulated luminescent nanoDot dosimeters(OSLnDs) positioned at 2, 4 and 6 ㎝ from the field edge, and the center axis of field. And the shielding ratio of 1 ㎜Pb was calculated by measuring the dose of OSLnDs positioned at 2, 4 and 6 ㎝ from the field edge.. As a result, for a 10×10 ㎠ and 15×15 ㎠ field, the off axis ratios were acquired 0.008-0.023 and 0.011-0.028, respectively. Also the shielding ratios of 1 ㎜Pb were acquired 0.868-0.888 and 0.807-0.842, respectively. These results provide data to protect organs at risk outside the radiation treatment field.

"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.
