Abstract ISO Standard 8529–1: 2001 on Reference neutron radiations is under revision. The
spectral data for the D 2 O-moderated 252 Cf field in the 2001 version of the standard refer …

The deviation in reading due to inverse square law is an important issue in the calibration of
neutron detection systems. The geometry correction factor of a neutron-measuring device is …

We have developed a lightweight portable neutron survey meter comprising a proportional
gas counter containing a mixed gas of methane gas and nitrogen gas for measuring the …

Abstract The D 2 O-moderated 252 Cf is a non-point neutron source used as a calibration
facility for measuring devices. The Bonner spheres spectrometer (BSS) is one of the …

A neutron standard field using a heavy-water moderated 252Cf source has been developed
at the National Metrology Institute of Japan, National Institute of Advanced Industrial Science …

An inter-comparison of the neutron calibration field of the D2O moderated 252Cf source was
carried out at JAEA and KAERI. Measuring the neutron spectra at KAERI by means of the …

A neutron irradiation experiment was performed to determine the neutron absorbed dose
rate response of a criticality accident alarm system detector. For this purpose, the authors …

We have developed two types of lightweight active portable neutron survey meter
comprising a proportional gas counter with a mixture of methane and nitrogen for measuring …

We are developing a new type of manganese bath for determination of neutron emission
rate of a radioactive neutron source. The manganese bath gas a multilayered structure …

An energy and directional independent neutron ambient dose equivalent monitor was
developed in order to obtain improved dose response over a wide energy range of neutrons …
