NEUTRON MONITOR DEVICE, AND NEUTRON MEASUREMENT METHOD

摘要

Provided are a neutron monitor device and a neutron measurement method which enable the intensities of neutrons having energies in the range of 10 KeV to several hundred KeV to be easily measured. This neutron monitor device (100) comprises: a first detector (1) comprising a hemispherical first main body (11) which is formed from PE, and which has a diameter of 31 mm, a first test piece (12) which comprises GaN, and which is disposed at the centre of the first main body (11), a Cd layer (13) provided to the outer surface of the first main body (11), and a B layer (14) provided to the inside of the first main body (11); and a second detector comprising a hemispherical second main body which is formed from PE, and which has a diameter of 27 mm, a second test piece which comprises GaN, and which is disposed at the centre of the second main body, a B layer provided to the outer surface of the second main body, and a Cd layer provided to the inside of the second main body.
