Jun, T. Nagaoka, S. Moriuchi] Experimental assessment of the cosmic ray ionising component at ground level has been carried out using a high purity germanium (HPGe) spectrometry system together with a NaITl scintillation detector. A 14 litre spherical ionisation chamber was used simultaneously in order to distinguish between the dose rate from gamma rays below 3 MeV and that from the cosmic ray ionising component detected in the higher energy region. Various cosmic ray dose rates and corresponding count rates were made available by utilising the shielding effect of a multi-storied building, including measurements at an outdoor flat and a mountain top. As a result Y = 30.25 XG + 1.42 and Y = 19.83 XN + 1.32 were derived, where Y is dose rate due to cosmic ray ionisation in nGy h-1, and XG and XN are the corresponding count rates in cps measured by the HPGe and NAITl spectrometers, respectively, in the region of 3 to 100 MeV.
