DURRIDGE scientists and affiliates have been invited to present original research at conferences around the world. The following presentations highlight the use of RAD7 and DURRIDGE accessories.
Measuring Radon in Water with the DURRIDGE RAD7 Continuous Radon Monitor
Measuring Radon in Water with the DURRIDGE RAD7 Continuous Radon Monitor

This presentation explores the following topics:

  • RAD7 Overview & Principle of Operation
  • Measuring moderate radon activity concentration levels in discrete water samples – RAD H2O
  • Measuring low radon activity concentration levels in discrete water samples – Big Bottle System
  • Continuous, fast-response measurement of radon and thoron in water – RAD AQUA
  • Continuous, slow-response passive measurement of radon in water – Water Probe
  • A few other methods – radon from sediment samples and dissolved radium

Radon as an Environmental Tracer for Geological Studies
Using Radon as a Tracer for Mapping NAPL Contamination

In February 2021 DURRIDGE’s CEO Carlos Bielicki and chief scientist Dr. Stephen Sadler delivered the following presentation to the Licensed Site Professionals Association (LSPA), detailing three uses for radon as an environmental tracer:

  • Groundwater / Surface Water Interaction
  • Vapor Intrusion
  • NAPL (Non-Aqueous Phase Liquid) Survey

This presentation is available as a PDF and as a 1-hour video:
