Spectrometer SDMF-1608 Mobile   Увеличить Цена:  3,678,650.00  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 features Simultaneous 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).  Application  Monitoring in nuclear facilities.  Earth physics.  Nuclear medicine.  Measurement of effective dose rate of secondary neutrons and gamma-ray at medical accelerators (LINAC).  Research in materials.  Fast neutron flux standard. Calibration of any kind of integral dosimeters of neutron and gamma radiation.
