L'explication/l'anotation:For source detection of neutron and nuclear gamma ray, constructing in
view point particle flux density, compared with level nature
ííîãî background.
La description détaillée de marque:Evaluation of dose equivalent rate of neutron and nuclear gamma rays.
provision of physical safety of fission materials in conditions
gatekeeper's office and check points. Source detection
neutron and nuclear gamma ray, being in moving transport
funds.
multifunctionality and possibility of independent use
different detectors.
possibility of increased sensitivity at the expense of surge in the number of
detectors.
possibility of prompt service of significant territories.
organization possibility of quasi-stationary items of radiological
control.
possibility of work in conditions of hard (field) climatic and
mechanical strains.
