This system allows activity quantification of liquid samples of waste disposal plants.
Precise quantification is obtained via a NaI(Tl) with Multi-Channel Analyzer probe installed in a low background well.
A water-tight Marinelli beaker is placed inside the well. Liquid is then sampled from tanks and stored in the Marinelli where measurement takes place with high geometrical efficiency.
The quantitive software allows data acquisition, ROI (Region Of Interest) definition and isotope identification, with consequent activity determination for each ROI.

The system is composed by:

• Low background shielded well.
  The well is made of iron with epoxy paint finishing. Standard shielding is 50 mm lead + copper internal sheet. OPTION: 100 mm lead shielding upon request
• 2”x 2” NaI (Tl) + PMT Probe with integrated high voltage generation, amplifier and 512 channels MCA; (a bigger number of channels is available under request)
• Quantitative Software for data acquisition, display and analysis of the spectra (peak recognition with automatic background subtraction);
• Software for energy and efficiency calibration
• Report generation

TELESERVICE UNIT

This unit allows to remote control the spectrometric software via ETHERNET connection. Remote access allows Picomed technical personnel to verify any malfunction and restore the system proper functionality. Also, it allows easy installation of eventual software updates. Customer should prepare a socket with RJ45 connector and supply information about IP address and network configuration.
