BOX COUNTER

CONTAMINATION MONITOR FOR SMALL ITEMS

The BOX COUNTER system is designed to perform a fast gamma contamination check of laundry, waste bags, tools and other small objects. 

Measurement results, alarms and malfunctions are displayed by the control console as well as the alarm unit.

The BOX COUNTER system can be easily moved and relocated by the user thanks to 4 pivoting and lockable wheels. The mechanical structure is made of stainless steel, all internal and external surfaces are specifically designed to be easily cleaned and decontaminated.

The 70x70x83 cm measuring chamber is accessible through 4 side doors. Up to six detectors can be installed, 4 in the doors, 1 in the top and 1 in the bottom side.

The available versions are:

  • 2U – two plastic detectors each installed in a side door
  • 4U – four plastic detectors each installed in a side door
  • 6U – six plastic detectors, four of which installed in the side doors, and two in the upper and lower sides of the measuring chamber
  • 6U NORM - five plastic detectors in the side doors and in the bottom of the measurement chamber, and a 2”x2” NaI(Tl) detector with MCA in the top of the measurement chamber

 
The detectors are large plastic scintillators, shielded with 10 mm lead sheets, in order to minimize the environmental radiation background. The system can reach an MDA as low as 4 kBq (Cs-137) in 10 seconds.

The control console consists in a touch-screen PC installed on the top of the system, equipped with an ELSE NUCLEAR management software.

The software allows to:

  • activate the measurements
  • analyze, display and save the measurement data
  • set the operational parameters such as alarm thresholds, detector enabling and calibration factors
  • activate, mute and reset the alarm and malfunction statuses through relay switches
  • perform a quality check to verify the proper functioning of the system
