Purpose

A stationery multifunctional professional device is aimed to measure:

• ambient dose equivalent rate of gamma-radiation Ḣ*(10);
• ambient dose equivalent rate of neutron-radiation Ḣ*(10);
• flux density of thermal neutrons.

The dosimeter is intended for use at nuclear stations, plants of nuclear industry, nuclear fuel cycle enterprises, and also at the companies which use the sources of ionization radiation. It can be used as an independent device or a part of automated radiation monitoring system for operative and periodical control of radiation situation.

Features

• light three-coloured (green, yellow, red) and sound alarm about exceeding threshold which are viewed from the distance 20 m;
• an automatic identification of radiation detector connected to the measurement console;
• there is a possibility to set a sensitivity coefficients, dead time and thresholds (preliminary and alarm) in radiation detector by user;
• there is available of indication by console USR-05 and send to the upper level via communication line RS-485 with using exchange protocols Modbus RTU or DiBUS (at the Customers choice) such information as: efficiency of radiation detectors, measurement results and cases of exceeding of setting threshold levels;
• there is a possibility of connection from 1 to 8 mono or different type radiation detectors from the dosimeter-radiometer;
• to provide a light-sound alarm at the installation place by means of block BUS-04 (if there is in the order);
• it is available to connect to personal computer and work with dosimeter-radiometer via software «TETRA_Checker», «TETRA_Reporter», «Atlant-Monitor»;
• storage of up to 10 000 measurement results in the non-volatile memory of the measurement console and there is available to send this data to a personal computer or to the systems of upper level;
• a protection degree against penetration of solid objects and water ? IP67;
• a dosimeter-radiometer consists of a measurement console UIK-05 and radiation detector in the quantity no more 4 pcs. The Customer chooses the list of radiation detectors while making an order. The radiation detectors of MKS-2020 has a technical ability to operate without measurement console UIK-05 in the automatic system of radiation control.
