Instruction in the setup and use of the RAD7 and accessories
DURRIDGE has been busy preparing videos explaining how to set up and use the RAD7 radon monitor, the CAPTURE data acquisition and analysis software, and several related accessories.
All research papers are in HTML format unless otherwise stated. PDF copies are available upon request and may be viewed using Adobe Reader.
The following articles explore specific advantages of DURRIDGE products.
This article explains that when a RAD7 is used in the presence of CO2, the thoron measurement is diminished more than the radon reading, and that therefore the 220Rn/222Rn ratio decreases as a function of CO2 concentration.
An examination of the suitability of the RAD7 for short term radon tests.
This document compares the RAD H2O, Big Bottle System, RAD AQUA, and Water Probe.
When calibrating an instrument for thoron measurement, it is necessary to use a thoron sample of known strength and to account for its short half life.
Sniffing for thoron with a RAD7 is the quickest way to locate a radon point of entry.
The RAD7's method of measuring radon allows it to be used repeatedly without requiring an excessive recovery time between separate measurements.
Soil Gas Measurement (HTML)
This article explains how a soil probe is used with a RAD7 to measure radon concentrations in soil gas while preventing the sample from being diluted by outside air.
This article explains how better time resolution and higher sensitivities can be achieved with new radon measurement technologies.
This article explains how the RAD7 and an air-water exchanger can determine the radon activity in coastal ocean waters on a continuous basis.
