“…Results obtained with AIRDOS were compared with Liulin dosimeter [7] in selected flight and long term measurement at high mountain observatory [32]. Differences in cumulative dose in silicon measured by Liulin and AIRDOS during the whole measurement campaign were below 10% with systematic error +4.8% [32]. Please note that this comparison was done for deposited energies above 250 keV.…”

“…Where 𝑘 Liulin/Airdos = 1.05, it represents different channel width of Liulin and AIRDOS and this systematic difference is estimated as 5% (lowest estimation of this systematic difference is 4.8% by [32]), 𝑘 Sv/Gy = 2.45, it is a mean value of a calibration factor for Liulin by the work [36] for the geomagnetic cutoff rigidities from 3.5 to 8.6 GV. Calculated values for the three AIRDOS devices are displayed in the graphs in figure 10 for the specific flight.…”

This article introduces a new open-source dosimeter AIRDOS intended for measurements on board aircraft. In-flight measurement of a mixed radiation field is a challenging deal that requires a small low-power-consumption battery-operated lightweight device with long endurance. A new innovative electronic design with a silicon PIN diode used as a sensor is presented, including full description and manufacturing documentation. The device was verified by measurements and compared with reference dosimeters widely used in aircraft dosimetry, such as Liulin MDU and HAWK TEPC. A comparison of the measurements with a computation model CARI 7 was performed as well. All the comparisons yield positive results within known errors. The new design of the dosimeter has a very satisfactory performance in terms of battery life and does not need calibration after manufacturing or recalibration after a long time of usage. Open-source design predetermines AIRDOS for future improvements and open-science.

Silicon detectors such as Liulin and AIRDOS are used for cosmic radiation measurements onboard aircraft. These measurements can be used for the verification of computer programs assessing aircraft crew radiation exposure. Recently performed intercomparison flights showed large variances of absorbed doses among individual detectors and significant differences between results of silicon detectors and computer programs. In order to explain for these differences, we have developed energy calibration method that can be performed on short flights. The method is based on cross-calibration of Liulin and AIRDOS deposited energy spectra with deposited energy spectra measured by Timepix which has superior detection properties in terms of energy resolution and the detection threshold. Moreover, the portion of dose which is omitted due to low sensitivity for low-energy deposits was calculated. The resulting absorbed dose rates at two intercomparison flights show significantly improved variation of results and better agreement with modelled absorbed dose rates.
