EXPERT-M Dosimeter-Radiometer (CE-certified) is meant for measuring of photon (Roentgen and gamma-) radiation dose rate ambient equivalent, for measuring of beta-particles flux density and for estimation of alpha-particles flux density, radiation being emitted from contaminated surfaces. The instrument makes it possible to estimate beta-, gamma- and alpha-emissive nuclides contamination of foodstuff, water, products, ground and other samples and to perform analysis of residential and non-residential premises contamination. The device is certified for compliance to specifications GOST R 50460-92. The device has a European certificate of conformity CE (European Directive 89 336 EEC). The instrument can be used for operative search of radioactive radiation sources or contaminated items; it can be used by personnel working in radiation monitoring agencies, public health, emergency condition service, secret services, environment protection agencies, by agricultural products manufacturers, builders, customs officers, bank workers and staff of other organizations usually operating under normal conditions, but solving problems related to identification of local radiation sources or certain items contaminated by radioactive nuclides (substances). EXPERT-M makes it possible to identify radiation safety of working places, residential premises, territory and radioactive contamination of objects, things, materials and samples. Testing of paper money and money packing is possible. The instrument is simple to operate; it has got only two operating controls. Information is displayed on a four-digit indicator panel. The instrument uses continuous measuring mode with change of measured values on the panel every 2 seconds; it is very convenient for operative monitoring. The instrument has got audio signaling for search of radiation source; audio signal frequency changes in case of a source identification. The instrument power supply is maintained by a Camelion (9V) battery or by a GP1604S-51 type battery. The instrument undergoes certification in the State Register Measuring Means in Federal Agency for technical regulation and Metrology; SANITARY AND EPIDEMIOLOGIC CONCLUSION as regards compliance with the state sanitary and epidemiologic regulations and guidelines Radiation Safety Norms as well as with Radiation Safety Norms provisions shall be issued. 1.2 Technical Characteristics Measuring range of photon radiation rate dose, mcSv/hour (mcR/ hour) 0.10-100 (10-10000) Range of photon energies at measuring of dose rate level, MeV 0.04-3.0 Energy dependence at measuring of dose rate, %, within the limits ±30 Measuring range of beta-particles flux density, flux being emitted by contaminated surfaces (Strontium-90 – Yttriyum-90), part./(cm2.min) 3-10000 Lower limit of registered beta-radiation energy, not above, MeV 0.05 Basic measuring error, %, within the limits ±25 Average value of proper background in g-mode, mcSv/hour (mcR/ hour) 0.08 (8) Alpha-particle flux density indication range, this flux being emitted by contaminated surfaces (Plutonium-239), part./(cm2.min.) 102-105 (??? 103-106) Lower limit of registered alpha-particles energy, not exceeding, MeV 3.0 Sensitivity anisotropy for Cesium-137 and Americium-241 in spatial angle 4r, %, within the limits ±40 Term of operational mode setting, min., not exceeding 1 Shift duration/ indication setting, s. 2/40 Duration of continuous operation (for measuring at the level of natural radiation background), hours, at least, power supply: - Camelion type (9V) battery - CORUND type (GP1604S-51) battery 50 300 Maintenance conditions: Temperature, oC Relative humidity, % From - 20 to +40 to 90 at 30°?
