Intrinsically safe radon monitoring and sampling

Our instruments provide a number of procedures for intrinsically safe radon monitoring and sampling.

  • We can sample work area, exhaust gases or process stream.
  • For radon gas and/or radon daughters run a tygon tube from the sample area to our monitor, or tap our radon monitor into the process stream or ventilation air stream. Pass the air or gas through a Lucas cell in our PMT radon monitor or through our solid state monitor.
  • For radon gas evacuate one or more of our intrinsically safe Lucas cells, carry the cell to the sample area(s), open a cell to the air or gas, and return to our PMT radon monitor.
  • For radon daughters carry a filter holder and a number of filters to the work areas, along with an intrinsically safe vacuum pump, and return the loaded filters to our radon monitor.
  • We also use our Lucas cell system to test for radon and radium in solution in effluent water.

We have laboratory-grade portable instruments with numerous capabilities.

  • Our PMT radon monitor features a photomultiplier tube with detectors including Lucas cell for radon gas and scintillation discs for radon daughters.
  • Our solid state monitor measures radon and thoron daughters. It is programmable and suitable for working level and other reporting methods.

INSTRUMENTS
  • We measure: radon - radium - thoron - radon daughters - alpha radiation.
  • The Lucas cell is recognized as the most sensitive and reliable method for these elements.
  • Intrinsically safe functions.
  • Sensitive to geochemical trace levels necessary for radon in lake water and for radon-thoron isotope ratios.
  • immune to beta and gamma radiation.
  • one monitor works with a number of (less expensive) detectors.
  • Our instruments are used around the world in exploration for uranium, oil & gas, groundwater and hydrothermal, and in environmental protection, health physics, earthquake prediction, and evaluation of hydrocarbon and NAPL contamination etc.
  • Same instruments used for radon and radium in soil, sediment, plant parts, rocks, water, soil gas, air, snow, food, and for radon and thoron daughters in air.
  • Winter and summer, from the Sahara Desert to the Canadian Shield, our instruments have faced up to severe field conditions.
  • In the radon business since 1968, our instruments are updated regularly with the most recent major re-design in 2015. Modern, low-power, field-rugged electronics. Some earlier versions still working after 40 years.
  • Continuous real-time monitoring and data recording.
  • RS232 port/pc software.
  • User programmable measurement intervals, sample and count periods and alarm level settings.
  • Can work in a tent without electricity or be carried from point to point in the field.
  • 50 readings per day. Results available immediately.
  • Portable. Rechargeable battery pack good for a long day in the field and recharges in a few hours.
  • Can be operated by junior personnel if carefully supervised.
  • EPA and CE Mark compliant.
