NUCLEAR WASTE CALIBRATION RESEARCH INDUSTRY NUCLEAR POWER PLANTS MANAGEMENT LABORATORIES CENTRES & MANUFACTURING MEDICINE • Gasless scintillation detector • Compact, lightweight and resistant design • User friendly, ease of use • High sensitivity, uniform response • Fast selection from stored measurement presets • Two settable alarm levels • Fast replacement of light-tight foil • Optional measurement of the dose rate The PAM-170 series activity meters are portable handheld instruments intended for the measurement of surface contamination. They contain a scintillator covered with light-tight foil, with a photomultiplier and two-channel processing electronics. 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 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. • B measure alpha and beta contamination but cannot discriminate them. It has the highest sensitivity to beta contamination, especially low energies. • C is a two-channel monitor, which can distinguish between alpha and beta contamination. Types B and C are suitable for nuclear plants, where the gamma background may be increased or variable. 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 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. The meter allows the measurement of the surface contamination in two modes: • Ratemeter - continuous measurement of the average pulse frequency to aid searching for a contaminated surface. • Contamat - integration measurement for deciding on contamination or cleanliness of a specific area in comparison with the set threshold. The meter is controlled using a graphical display with the possibility of backlit illumination and three push buttons. One or two channels can be displayed on the display simultaneously. The measured values can be displayed as count rate, or for specific selected radionuclides in units of activity, surface activity, emission and surface emission. The display shows the selected quantity digitally and/or as a bar-graph. PAM-170 can save up to 25 different presets for measurement mode, quantity and unit, radionuclide, response factor and alarm levels. For each channel the background radiation level can be measured manually and stored in memory. This background is then automatically deducted from the measurement results indicated on the display. The PAM-170 meters can optionally contain an integrated GM tube for measurement of the gamma dose equivalent rate. It is an additional measurement, which can give a warning to the operator of higher ambient radiation levels. The meter can also acoustically indicate pulses generated by the detector. Dual-channel monitors distinguish between pulse detection in the alpha channel and in the beta channel by a different sound. To carry the monitor you can use a portable carrying case that is included in the del

Battery life Temperature range from -20 to +40 °C The currently measured values in the "Ratemeter" mode and the results of the integration measurements in the "Contamat" mode can be stored in the measurement archive together with a time stamp. The archive can then be exported to a file. Service software is used to export the archive, and set the essential parameters or update firmware by means of a PC/notebook connected by a service port.
