DIAMON is a all-in-one portable detection system able to perform neutron spectrometry, to reconstruct neutron direction distributions and to properly derive field and operational quantities… in real-time! It's lightweight, small and compact and can be used as a portable monitor in battery mode (rechargeable) or as a stationary measuring instrument for continuous monitoring. 

Unlike standard neutron monitors, radiation protection quantities are directly calculated from the neutron spectrum and the recommended ICRP conversion coefficients.

Spectrometry: innovative design and proprietary unfolding code (UNCLE) allow a direct and real-time assessment of the neutron spectrum.
Dosimetry: the neutron spectrum is used to perform an accurate evaluation of the field and operational quantities of interest (Fluence, H*(10), h*(10), field fractions… ).
Field Direction: a proprietary method and algorithm give real-time information about the 3D direction distribution of neutrons.
