Description:
Small article monitor (6 Counters, 1 Door, Low energy)
Quickly and thoroughly monitor articles used in radiation-controlled areas for radioactive contamination with a precise, computerized, measurement control solution. The Thermo Scientific™ SAM12 Small Articles Monitor is a well-proven, reliable, rugged instrument that monitors articles for gamma-emitting radionuclides and easily achieves clearance limits for higher energy gamma emitters such as 137Cs and 60Co. This monitor allows dynamic discrimination between natural (NORM) and man-made radiations, and offers a unique feature for 60Co monitoring.

SAM12 Small Articles Monitors are operating in a large number of nuclear power plants worldwide, demonstrating why this instrument is the ideal method of monitoring for unrestricted release.

  • Background shielding and compensation reduce shine and scatter effects. 
  • Measures fixed, smearable, internal and external gamma contamination simultaneously
  • Measures down to clearance levels less than 5000 dpm (83 Bq)
  • Discrimination of Natural Occurring Radioactive Material (NORM) via Natural Background Reduction (NBR) Cobalt Coincidence monitoring
  • Provides excellent uniformity of response across the chamber
  • Monitors for single particles or distributed contamination with equal effectiveness
  • Able to check for changing background during the measurement
  • Fast, easy and thorough monitoring with no special training or supervision required
  • Reduced time to count
  • Includes large touch-screen color LCD display; no keyboard required
  • Thermo Scientific™ ViewPoint™ Enterprise compatibility
  • Automated calibration and checking routines
  • Upload and download easily via USB
  • Lead shielding: 1 or 2 in. (2.5 or 5cm) lead shielding may be specified as standard

Options: 

SAM12 mounting stand for floor bolting; USB dot matrix printer; and jigs for both one- and two-door SAM12 monitors
