The distributed architecture approach taken by the Alpha Sentry CAM system enables the user to monitor potential leak situations from a point safely outside the affected area.
The Alpha Sentry Continuous Air Monitor (CAM) System resolves many of the issues facing Alpha CAM users today. A patented diffusion screen removes 95% of the unattached radon daughters from the air sample (as much as 90% of the radon daughters are unattached in typical laboratory environments).
In addition, the spectroscopic algorithm (which uses a stripping method instead of ROIs) is extremely effective at subtracting out the radon daughter interference from the transuranic region of interest.
This physical and mathematical radon reduction increases the sensitivity of the Alpha Sentry system, which in turn translates into a lower false alarm rate.
The distributed architecture approach taken by the Alpha Sentry CAM system enables the user to monitor potential leak situations from a point safely outside the affected area. Multi-dropping up to eight sampling heads off a single operator interface (ASM1000), enables the location of the sampling heads in the room while the ASM1000 resides in the hallway.
Sharing the operator interface resource lowers the cost per sampling location. It also makes networking to a lab-wide computer easier - there's only one connection per eight sampling heads.
In the Alpha Sentry network, the detector and multichannel analyzer electronics in each sampling head count the activity on the filter and determine if an acute release has occurred. In addition, the ASM1000 reads the spectrum from each head at regular time intervals, applies a precise spectroscopic algorithm, and determines if a chronic release has occurred. In either case, both the sampling head and the ASM1000 signal an alarm.
