1 DESCRIPTION AND OPERATION
1.1 Purpose of use
The MKS-05 “TERRA” dosimeter-radiometer (hereinafter called the
dosimeter) is designed to measure ambient dose equivalent (DE) and
ambient dose equivalent rate (DER) of gamma and X-ray radiation
(hereinafter called photon-ionizing radiation), and surface beta-particles
flux density.
The dosimeter is used in ecology research;as visual aids for
educational establishments, for dosimetry and radiometry control at
industrial enterprises; apartment, building, and construction control, ground
surface of infields and vehicles control, personal radiation safety.
