  • Page 1 Scientific and Production Unitary Enterprise АТ2522 RADIATION DETECTOR (ALPHA SENSOR) User's Manual Contents Description and operation3 Purpose3 Specifications4...
  • Page 2 The purpose of this User's Manual is to explain the operation principle and design of AT2522 Radiation detector (Alpha sensor) (further referred to as alpha sensor). It contains main specifications and other data to provide correct and fully-functional operation of alpha sensors.

  • Page 3: Description And Operation

    Description and operation Purpose Alpha sensor is an indicator of radioactivity and is designed for quick assessment of surface contamination by alpha nuclides, i.a. polonium-210. Alpha sensor belong to the type of portable devices and is suitable for radiation control professionals as well as for individuals interested in radiation situation at workplace, living and recreation areas, as well as for training purposes.
  • Page 4 Specifications Alpha sensor triggers audio, vibration and visual alarm in case of detection of surface contamination by alpha-active radionuclides. Detection time of surface contamination of 0.1 Bq/cm does not exceed 1 s. Initialization time does not exceed 5 s. Electric power supply is provided by a built-in rechargeable battery. Time of continuous operation with fully-charged battery is at least 500 h when the display is OFF, and at least 40 h when the display is ON.
  • Page 5 Index of reliability: ≥10000 h Mean time to failure − ≥10 years − Mean operating life Up to 1 h. − Mean time to recover Alpha sensor contains no precious materials or non-ferrous metals.

  • Page 7 20.1 Description and operation 20.1.1 Operating principle The principle of alpha sensor’s operation is based on the detection of alpha particles emitted from the tested surface by ZnS(Ag) scintillation detector with dimensions of 55×45×1 mm. 20.1.2 Design See Figure 1 .1 for general view of Alpha sensor. Figure 1.1 Alpha sensor consists of housing and removable protection plate which covers the detector.
  • Page 8 20.2 Marking Marking labels are generated automatically by dedicated software. The end face marking is made by a film label with adhesive layer and has the following information: − Name and designation of alpha sensor Serial number − − Manufacturing year −...

  • Page 9: Pre-Start Procedure

    26 Pre-start procedure 26.1 General information Read this User's Manual thoroughly before the start of alpha sensor operation. Remove the alpha sensor and accessories from the packaging box. Check the list of standard equipment of the alpha sensor according to 19.1. Perform visual inspection of alpha sensor and its accessories: −...

  • Page 10: Intended Use

    34 Intended use 34.1 General information Exercise caution during operation of the alpha sensor. Carefully protect it from bumps and drops. Operate the alpha sensor with caution to avoid damage to the light protection film; otherwise it results in alpha sensor’s malfunction. Damaged films can be replaced by User according to instructions in Appendix A.
  • Page 11 When radioactive contamination has been detected, alpha sensor activates audio and visual (or vibration) alarms, displays the estimated value of alpha particles count rate from the surface. Find the borders of contaminated area by moving the alpha sensor over the tested surface at a height not more than 5 mm.
  • Page 12 “AlphaSensor” program by running the “Setup.exe” installation package file. When standard program installation procedure is over, the “AlphaSensor” shortcut appears on the desktop (see Figure 3.1). The “ATOMTEX” group with a shortcut for starting the “AlphaSensor” program will be created in the “START” menu.
  • Page 13 (“Programs→ATOMTEX→AlphaSensor”). Use standard Windows tools to exit the program. 37.2.5 Parameter settings Configure the connection to alpha sensor to provide proper operation of the program. Select the “Settings” menu on the main menu bar. This will open the “Settings” window (see Figure 3.2).
  • Page 14 Working window Status bar Figure 3.4 Working window area contains the following elements: − Alpha sensor status indicators: “CPU temperature”, “Battery temperature”, “Battery voltage” “Measurement” area, which displays the count rate. In − standby mode (the protection plate is attached to the alpha sensor’s housing) the screen displays a zero count rate value against gray background.
  • Page 15 the new settings are successfully stored, when the indicator is red, the settings are not stored. Make a new attempt to store the settings in case the settings have not been stored. The “Device control” window has three tabs: “Events”, “Signals” and “Functions”. Event types: “Device ON”...

  • Page 19: Maintenance

    38 Maintenance Maintenance is necessary to keep the alpha sensor ready for operation and to ensure fail-safe performance throughout its life. Maintenance consists in preventive activities performed at least monthly. Preventative activities include the following: − External check − Check the contents of alpha sensor’s delivery set according to 19.1.
  • Page 20 44 Storage Before commissioning store the alpha sensor indoors in the manufacturer's packaging at an ambient temperature from +5 °C to +40 °C and relative humidity ≤80 % (+25 °C). If the alpha sensor has been removed from its original packaging, store it at ambient air temperature from +10 °C to +35 °C, relative air humidity ≤80 % (+25 °C).
  • Page 21 49 Transportation The alpha sensor in original packaging allows transportation in any means of covered land transport and in pressure-sealed aircraft compartments with ambient air temperature range −20 °C to +55 °C and relative humidity ≤100 % (+40 °C). Thoroughly secure the properly packaged alpha sensor inside transportation carrier.
