This paper presents the establishment and characterization of a neutron calibration fieldusing a bare 252Cf source of low neutron source strength in Vietnam. The characterizationof the field in terms of neutron flux spectra and neutron ambient dose equivalent rateswere performed by Monte Carlo simulations using the MCNP5 code. The anisotropy effectof the source was also investigated. The neutron ambient dose equivalent rates at threereference distances of 75, 125, and 150 cm from the source were calculated and comparedwith the measurements using the Aloka TPS-451C neutron survey meters. The discrepancybetween the calculated and measured values is found to be about 10%. To separate thescattered and the direct components from the total neutron flux spectra, an in-houseshadow cone of 10% borated polyethylene was used. The shielding efficiency of theshadow cone was estimated using the MCNP5 code. The results confirmed that theshielding efficiency of the shadow cone is acceptable.
