Overview
SDMF-1608PRO Mobile –The neutron and gamma ray spectrometer -dosimeter is designed for measuring the
spectral neutron and gamma-ray flux
density in the real time. Based on the measured spectral fluence rate effective and absorbed dose
rate is calculated in a wide energy
range of neutron and gamma ray, as well
as ambient equivalent dose rate. For gamma-rays, spectrometer-dosimeter also calculates the exposure and
absorbed dose rate in the air.
When calculating the dose characteristics, the geometry of radiation
sources and irradiation conditions are taken into account.
Main featuresSimultaneous measurement of energy spectra of neutron and gamma ray. Measurement of neutron spectrum without
usage of bulky and heavy polyethylene moderators. Measurement of continuous (“white”) spectrum of gamma ray as well as of
linear (discrete) spectrum. Measurement of fast neutron and gamma ray flux density in absolute units. Maximum load at detector input 3 х 105 pulses, which
corresponds to the computable effective dose rate of 1.75 х 105 μSv/hr from 239Pu-Be source with frontal geometry. - Energy resolution of no
more than 2.5% for neutron with
energy of 14.5 MeV and no more than
9% for gamma
rays with energy
of 661 keV (137Cs).
