In their most recent recommendations, the International Commission on Radiological Protection (ICRP) proposed the use of a set of updated tissue and radiation weighting factors for the calculation of the effective dose. This recommendation was adopted in the European Union by the directive 2013/59/EURATOM in 2013 and implemented in the corresponding radiation protection regulations in Germany in 2018. In this study, we investigate the impact of the new weighting factors according to ICRP 103 on the dose rates of the effective dose due to the exposure of aircrew to cosmic radiation with the PANDOCA model for the description of the complex radiation field in the atmosphere. The application of the updated weighting factors leads to a reduction in the rate of the effective dose in the order of 20% to 30% depending on atmospheric and geomagnetic shielding as well as solar modulation.
