Intercomparisons

- ACREM

- CAATER
As in many other areas, PTB also participats in international intercomparisons on dosimetry at aviation altitudes where the accuracy of the doses measured with different instruments are to be compared.


ACREM

Air Crew Radiation Exposure Monitoring
1997-1999
acrem in flight
In cooperation with the Austrian Research Center Seiberdorf and Lufthansa AG, measurements were performed on approximately 40 long-distance flights. Within the scope of this project, the suitability of specific detectors for dosimetry of the complex radiation field at flight altitudes was verified.





DOSMAX

Dose assessment during solar maximimum
2000-2004
Flugkoffer
Several European countries participated in these comprehensive measurements at flight altitudes. Many participants used so-called tissue-equivalent proportional counters with the aid of which long-term measurements were carried out at flight altitudes. For this purpose, PTB has equipped an A340 of the German Deutschen Lufthansa AG with a flight case.





CAATER

Co-ordinated Access to Aircraft for Transnational Environmental Research
04.05.2003 - 06.05.2003
CAATER TEAM This measurement campaign was organized to offer the DOSMAX participants the opportunity of simultaneously performing dosimetric measurements in an airplane under constant flight conditions. Two flights were started from the DLR base in Oberpfaffenhofen (OBF): OBF-Aalborg-OBF and OBF-Rom-OBF. The flights were performed on flight level 320 (≈ 9.7 km) and flight level 400 (≈ 12.2 km).
