Monitor types A, B and C have suppressed sensitivity to gamma radiation and thus low response to gamma background. This allows setting of lower alarm levels comparing to the D and E monitor types. • A measures only alpha contamination and is therefore designed especially for plants for the production and / or processing of nuclear fuel, uranium mining and / or processing. • C is a two-channel monitor, which can distinguish between alpha and beta contamination. Monitor types B and C are suitable for nuclear power plants, where the gamma background may be increased or variable. Monitor types D and E have increased sensitivity to gamma radiation and thus higher response to gamma background. This prevents them from setting as low alarm levels as can be set for the B and C monitor types. • D measures all types of radiation (alpha, beta, gamma) in one channel. It is suitable for nuclear medicine workplaces where Tc-99m radionuclide and possibly others pure gamma emitters are used. • E measures all types of contamination and can discriminate alpha. It is suitable for training or experimental workplaces. HF-6 monitors use four scintillation detectors to measure hand contamination, two for each hand, for simultaneous measurement of the palm and the back of the hand. Two scintillation detectors are used to measure foot contamination. The monitor measures the background radiation when not being used, and subtracts this from the user measurements to allow operation in higher background areas. As soon as any sensor detects that a person is present, the background measurement is interrupted. Once the user has achieved the correct measurement position, the measuring process begins. Visual indicators and voice prompts help to achieve the correct position. The monitor guides the workers during the measurement sequence and informs them of the results by voice and visual display. Measurement results and events are stored and can be exported to a PC for records and analysis via Ethernet (Modbus, TCP/IP) or external USB flash disk. Using the touchscreen, a predefined set of parameters can be selected, language changed and the monitor can be switched to the service mode (basic diagnostics and settings). A PC with service software is used for full diagnostics
