Doza

A simple and inexpensive radiation monitoring system for radiation-hazardous facilities, such as radionuclide source storages, isotope warehouses, clinical radionuclide diagnostics and therapy departments, PET centers, metrological laboratories where work with ionizing radiation sources is carried out, etc.

Purpose: measurement of the product of the air kerma on the cross-sectional area of the X-ray beam at the output of the X-ray machine; determination of the power of the product of the air kerma on the cross-sectional area of the X-ray beam of light at the output of the X-ray machine; monitoring the stability of medical X-ray machines during their operation; verification of clinical dosimeters with pass-through ionization chambers (after certification as a working standard).

Appointment: The installation is designed to detect radioactive contamination of the surfaces of controlled objects.

Purpose: sampling for aerosol analytical filters of the AFA RSP-20 type control of the flow of gaseous mixtures in the sampling path Features: a rack with a sampling line fixed on it, an FD-1D filter holder and a rotameter.

Stationary complex for monitoring various parameters of the radiation situation, depending on the type of connected detection units: - continuous monitoring of gamma and neutron radiation in rooms and workplaces; - assessment of alpha and beta and gamma contamination of surfaces of objects, personnel clothing and small items. Purpose: measurement: ambient dose equivalent power of photon and neutron radiation; alpha and beta radiation flux densities; surface activity of Pu-239 and Sr-90+Y-90 radionuclides; alarm about exceeding the set thresholds.

The filter holder FD-05D is designed to install aerosol and iodine filters in it, in an amount of up to 8 pieces. The filters are arranged sequentially. It is used in sampling systems of gas-aerosol media at radiation-hazardous and other production facilities.

Dosimeter is a gamma-beta radiation radiometer for working in "dirty" conditions. Allows you to switch modes and take measurements in conditions of radioactive contamination. Measurement of the beta radiation flux density is carried out with automatic subtraction of the gamma radiation background. Purpose: measurement of the ambient dose equivalent of H*(10) gamma radiation; measurement of ambient dose equivalent of H*(10) gamma radiation; measurement of beta particle flux density; estimation of the counting rate with combined measurements of gamma and beta radiation.

Installation for verification and calibration of individual beta radiation dosimeters. Properties The unit transmits units of absorbed dose (PD) and absorbed dose rate (MPD) of beta radiation in a tissue equivalent substance at a depth corresponding to a surface density of 7 mg•cm-2; the transition to units of the individual equivalent of the Hp dose (0.07) in sieverts from units of beta radiation absorbed in the tissue in gray is carried out using conversion coefficients recommended by the international standard ISO 6980-3:2006; the installation can be used in metrological bodies for verification of individual beta radiation dosimeters such as DMC 2000 XB, EPD Mk2 and others.
