Upgrade of the Hungarian PILLE-ISS onboard thermoluminescent system for the dose assessment during extravehicular activities
The paper presents results of on-ground (pre-flight) calibrations and flight tests (cross-calibration and in situ measurements) of the new, Modified PILLE-ISS Dosimeters with reduced shielding, developed for the radiation monitoring of astronauts during their extravehicular activity (EVA) on board the International Space Station (ISS). The smaller dimensions and weight of the modified thermoluminescent dosimeter allows ergonomic and safe use during EVA, when the dosimeter kit is worn in the outer pocket of a spacesuit. The special design of the detector housing makes it possible to estimate the dose to the astronaut's skin during EVA more accurately. Both pre-flight calibration with high-energy protons and on-board cross-calibration at ISS showed that the variability of the relative sensitivities does not exceed (5–10)% for any of the Modified PILLE-ISS Dosimeters. The additional dose received by astronauts during ISS EVAs in 2023 was in the range (0.37–0.75) mGy (in water) based on the measurements. The corresponding dose rate outside ISS is consistent with the previous readings of other dosimetric equipment installed on the outer surface of space station.
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.
