Due to the performance characteristics of gadolinium converter dispersed uniformly in the photostimulable phosphor layer of
the BAS-ND Imaging Plate,
neutron irradiation on its surface is transferred to a secondary radiation
and the photostimulable phosphor detects the emission of the secondary
radiation.

Irradiated neutron
(wave length; 2.2 x 10-10 m)
generated from the nuclear reactor JRR-3M, Japan Atomic Energy Research
Institute.
BAS-ND is optimized to thermal neutron.
Caution
When neutron dose rate exceeds certain levels for BAS-ND Imaging Plate,
some components may be activated.
Those components are Eu (containing ratio 8.25 x
10-5 g/cm2)
and Mn (containing ratio 5.60 x
10-3 g/cm2).
