Thermo Fisher Scientific SAM's are operating at most North American power utility sites for releasing tools and small articles from controlled areas. This well shielded and robust design is available in several configurations to accommodate elevated backgrounds and specific monitoring tasks at control barriers.
Product Detail
The SAM12 builds on the rugged capabilities of the SAM11 to monitor articles for gamma emitting radionuclides. Readily measures down to clearance levels less than 5000 dpm (83 Bq), but adds sophisticared new electronics allowing dynamic discrimination between natural and man-made radiations, as well as a unique feature for Co-60 monitoring.
Qualities
Measures fixed, smearable, internal and external gamma contamination simultaneously
Measures down to 5000 dpm independent of mehtodology
Excellent uniformity of response across the chamber
Fast, easy and thorough with no special training or supervision required
Equally effective for single particles or distributed contamination
Discrimination of Natural Occurring Radioactive material via Natural Background Reduction (NBR)
Cobalt coincidence monitoring
Reduced time to count
Ability to check for changing background during the measurement
Large touch-screen colour LCD display - no keyboard required
Automated calibration and checking routines
Easy upload and download via USB
Viewpoint compatibility
"Don't Risk It when you Frisk It - just Slam It and SAM It!"
Performance in brief
4-detector version with 1" lead shielding detects 5000 dpm activity in 15 µR/h (0.15 µSv/h) background within 10 seconds. (90% confidence, <0.1% false alarms)
6-detector version with 2" lead shielding detects 5000 dpm activity in 100 µR/h (1 µSv/h) background within 30 seconds. (90% confidence, <0.1% false alarms)
