Intrinsically safe radon monitoring and sampling

  • Our instruments can use an intrinsically safe protocol, leaving the electronic instrument in a safe area and bringing a sample to it.
  • We can sample work area, exhaust gases or process stream.

Continuous Monitoring

  • For radon gas and/or radon daughters run a flexible 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.

Grab Sampling

  • For radon gas carry a sample container to the work area, fill it with ambient air and return it to the monitor
  • For radon daughters carry a filter holder and a number of filters to the work area, 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.
On-site engineers will, of course, ensure that all other fire, explosion and safety precautions are taken, including installing the flexible tube and collecting and carrying the sample.

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.

  • We measure: radon - radium - thoron - radon daughters - alpha radiation.
  • The Lucas cell is recognized as the most sensitive and reliable method for these elements.
  • 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.
  • In the radon business since 1968, our latest major instrument update was 2015.
  • Modern, low-power, field-rugged electronics. Some earlier versions still working after 35 years.
  • Continuous real-time monitoring and data recording.
  • Winter and summer, from the Sahara Desert to the Canadian Shield, our instruments have faced up to severe field conditions.
  • Intrinsically safe functions.
  • Sensitive to geochemical trace levels necessary for radon in lake water and for radon-thoron isotope ratios.
  • Can work in a tent without electricity or be carried from point to point in the field.
  • 50 readings per day. Results available immediately.
  • 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.
  • Same instruments used for radon and radium in soil, sediment, plant parts, rocks, water, soil gas, air, and snow, and for radon daughters in air.
  • EPA compliant.
