DESCRIPTION: Technical Associates VAP-X-Radon Tritium Monitor is a sensitive, rugged, portable instrument
for detection and measurement of airborne VADO-zone/soil air. Its' subtractive balanced chamber electrometer
circuit decreases background effects to negligible levels and its deionized and filtered intake reduces to negligible
levels spurious effects from smoke, dust and existing ionization in the air. It has AC line and battery operation and
it may be left on permanently without fear of ``running out of battery''. Inlet and outlet hoses and basic
underground soil air collection are included.The VAP-X-Radon will measure airborne tritium as free hydrogen or
as volatile chemicals in concentrations as low as 1 x 10-7 uCi/cc of air. (3.7 KBq/m3)
All instruments are calibrated at the factory. Calibration check may be performed in the field with a microCurie
level Beta or Gamma source. Background chamber may be disconnected to check linearity of response on a
gamma calibration range. User friendly calibration controls are provided.
Uses:
• Pin-point the source of a leak
• Map your underground plume
• Locate edge of plume
• Locate problem areas
Advantages:
• Allows user to chase down contamination source
• Optional Sr-90 detection or detection for other nuclides
Situation:
Sometimes you need to extract vapor from the soil at a series of points in order to track down a radiation
leak or map a spreading plume. There may be some useful existing holes or wells but you need data
from additional points at different depths. Model VAP-X-Radon is designed specially to help you
accomplish this task.
