“…This, along with recent improvements to some of the underlying transport models and numerical procedures within HZETRN (Slaba et al, 2009;Slaba et al, 2009;Wilson et al, 1995), provides an opportunity for another round of verification and validation benchmarks. Other recent work on the impact of galactic cosmic rays on radiation exposure of aircrew may be found in Beck et al (2007), Bottollier-Depois et al (2009), Lindborg et al (2004) and Takada et al (2007).…”

“…The dose and spectral measurements above the Pfotzer maximum facilitate the characterization of the source of cosmic radiation exposure at aviation altitudes [ Mertens , ]. The balloon flight trajectory near Fort Sumner is located at cutoff rigidities where aviation radiation model uncertainty is near its maximum [ Bottollier‐Depois et al , ].…”

The NASA Radiation Dosimetry Experiment (RaD‐X) stratospheric balloon flight mission obtained measurements for improving the understanding of cosmic radiation transport in the atmosphere and human exposure to this ionizing radiation field in the aircraft environment. The value of dosimetric measurements from the balloon platform is that they can be used to characterize cosmic ray primaries, the ultimate source of aviation radiation exposure. In addition, radiation detectors were flown to assess their potential application to long‐term, continuous monitoring of the aircraft radiation environment. The RaD‐X balloon was successfully launched from Fort Sumner, New Mexico (34.5°N, 104.2°W) on 25 September 2015. Over 18 h of flight data were obtained from each of the four different science instruments at altitudes above 20 km. The RaD‐X balloon flight was supplemented by contemporaneous aircraft measurements. Flight‐averaged dosimetric quantities are reported at seven altitudes to provide benchmark measurements for improving aviation radiation models. The altitude range of the flight data extends from commercial aircraft altitudes to above the Pfotzer maximum where the dosimetric quantities are influenced by cosmic ray primaries. The RaD‐X balloon flight observed an absence of the Pfotzer maximum in the measurements of dose equivalent rate.

“…PANDOCA, SIEVERT, etc. (Clairand et al 2009;Bottollier-Depois et al 2012;Matthiä et al 2014). Furthermore, most models also permit to assess the dose quantity H*(10) which can be measured, either directly by a Tissue Equivalent Proportional Counter (TEPC) or indirectly by the absorbed dose in silicon with a corresponding conversion factor, determined either in particle accelerator experiments (Mitaroff & Silari 2002) or in the radiation field at flight altitudes (Wissmann et al 2010).…”

Space weather can strongly affect the complex radiation field at aviation altitudes. The assessment of the corresponding radiation exposure of aircrew and passengers has been a challenging task as well as a legal obligation in the European Union for many years. The response of several radiation measuring instruments operated by different European research groups during joint measuring flights was investigated in the framework of the CONCORD (COmparisoN of COsmic Radiation Detectors) campaign in the radiation field at aviation altitudes. This cooperation offered the opportunity to measure under the same space weather conditions and contributed to an independent quality control among the participating groups. The CONCORD flight campaign was performed with the twin-jet research aircraft Dassault Falcon 20E operated by the flight facility Oberpfaffenhofen of the German Aerospace Center (Deutsches Zentrum für Luft-und Raumfahrt, DLR). Dose rates were measured at four positions in the atmosphere in European airspace for about one hour at each position in order to obtain acceptable counting statistics. The analysis of the space weather situation during the measuring flights demonstrates that short-term solar activity did not affect the results which show a very good agreement between the readings of the instruments of the different institutes.
