MAIN ADVANTAGES

  • Scintillating gasless  detectors with integrated evaluation processor allowing easy calibration and quick replacement of damaged detector in the installation site
  • Variability of detectors for different types of contamination, including single, or double channel implementation
  • Excellent full body coverage, including sides of legs, hands, and insteps
  • Tight geometry for high efficiency alfa contamination measurement on hands
  • Advanced algorithm for automatically determination time of measuring ensures high persons throughput.
  • User friendly GUI with several colour displays
  • Possibility to install multiple language versions to communicate with measured persons, including voice instructions
  • Extremely easy access to detectors facilitates their maintenance
  • Possibility to use contamination detectors also for other monitors from VF’s production facilitates maintenance of these devices
  • Possibility to identify measured persons using an ID reader (optional accessory)
  • Different monitor variants with wide range of optional accessories
  • Possibility to communicate with a parent system through a standard Ethernet interface

  

DESCRIPTION

ExitScan-2 is a two-step, full body personnel contamination monitor, designed to inspect personnel leaving controlled areas primarily in nuclear power plants. The monitor checks for contamination occurrence of alpha, beta, and gamma emitting radionuclides (depending on used detectors).

ExitScan-2 can be supplied in these configurations:

  • FULL with 26 detectors
  • OPTIMAL with 18 detectors
  • OPEN with 18 detectors

The FULL and OPTIMAL versions, unlike the OPEN version, allow blocking the passage contaminated or unmeasured persons using barriers or doors (optional accessory). The OPEN version is lightweight, and consists only of a pedestal and a detector wall.

The figure bellow shows the difference in detectors placement between the FULL (left), and OPTIMAL/OPEN versions (right):

  

MEASUREMENT

The monitor measures background radiation level, until enters of person in. Then the measuring of the front of body begins. Once achieving the correct position, allowing maximum detection efficiency, the measuring process begins. Visual indicators and voice guidance help to achieve the correct position. After finishing the first phase, the user is asked to turn around, and the process repeats for the back of the body. To ensure the shortest possible measuring time, and greatest throughput, a sophisticated statistical evaluation algorithm is used.

The device reports measurement results or possible malfunctions on several displays.

In case of exceeding set signalling level of contamination, a visual and acoustic signal is activated.

Movable head contamination monitor, supplied as an optional accessory, will automatically approach the measured person’s head (range of motion approx. 0.5 m). The monitor can also be optionally equipped with contamination monitor for small objects, which are measured during the person measurement.
