Abstract

Measurements of the complex cosmic radiation field in aircraft at altitude are madewith a passive survey meter comprising routine-use thermoluminescent detectors and etched track detectors. The energy dependence of response of the etched track detectors used to determine the neutron component has been characterized, partly, up to a neutron energy of 180 MeV. The neutron detectors are routinely calibrated in the CERN/EC Reference Field. The 15% determination level fortotal dose equivalent is 100 μSv. The evidence is that the passive survey meter provides a reliable determination of route dose.
