Abstract

Electromagnetic noise from radiation detectors and from an aircraft itself were examined using a field meter. It was proved that the electromagnetic noise from radiation detectors is smaller than that from the aircraft.
Dose equivalent rates due to cosmic ray neutrons and ionizing radiation were measured using a moderated 3He counter and a CsI (Tl) scintillation counter in a commercial aircraft at an altitude of approximately 10 km, between Narita, Japan and Vancouver, Canada. The measured data were compared with the results calculated using calculation code (CARI2), and it was found that both agree approximately.
