It is possible effectively delivery of any quantity.
Dosimeter-radiometer SPEKTRA MKS-11 (MKS11, MKS 11, mkc-11, mkc11, mkc 11)
Dosimeter-radiometer SPEKTRA MKS-11 is designed to measure ambient dose equivalent rate of gamma-and X-rays (hereinafter Maeda photon ionizing radiation), determining the intensity of neutron radiation, as well as identify the type of radionuclide.
The instrument provides for the accumulation, preservation of non-volatile memory and identification of gamma-amplitude spectra.
The device is used for discovering and localizing radioactive and nuclear materials in their gamma and neutron radiation in order to prevent illicit trafficking, as well as enterprises and institutions, where the works with sources of gamma and neutron radiation.
