Alpha Air Monitors


  • Description
  • Specifications

 

Thermo Scientific™ ALPHA-7A Air Monitor is designed to provide early warning to workers exposed to airborne releases of alpha-emitting radionuclides.

Modern, PC-based continuous air monitor provides faster, more powerful algorithms for the identification and quantification of airborne releases of alpha-emitting radionuclides, primarily transuranics such as 238Pu and 239Pu.

The ALPHA-7A has adjustable alarms, at both DAC and DAC-hour levels, to rapidly warn workers of potentially dangerous releases. In addition to monitoring work areas, it is also an excellent solution for monitoring stacks and ducts.

  • Can serve as a stand-alone CAM or be incorporated into Ethernet-based network
  • Simultaneously monitors up to 8 isotopes
  • Advanced peakshape algorithms; calculates isotopic activity by mapping peaks rather than using regions of interest (ROI)
  • Alpha-spectral data updated every second
  • Concentration, dose, and activity alarms
  • Pentium-class PC-based, Windows 2000 operating system
  • Removable filter holder cartridge
  • High-speed connections via 10-base T Ethernet connection
  • 4 to 20mA analog input and output capacity
  • High-visibility display for status and messages
  • New isotopes easily added from library using any ODBC database manager
  • Automatic gain control based on naturally occurring peaks
  • Tracks alpha-emitting daughter products
  • Full-featured, Windows-based client software presents graphical displays of spectrum and status to any networked or local PC

 

Two detector designs:

  • Radial entry head for ambient air monitoring
  • Inline head for process or stack monitoring applications
  • Either head may be used remotely from the central display and control unit

 

Compatible with:

  • Thermo Scientific RAP-1 pump
