In the field we use the Rad7 instrument to accurately measure radon in groundwater & surface water.
The Radon Analytical Laboratory also operates a comprehensive suite of other instrumentation for the monitoring and analysis of natural radioactivity resulting from radon (222Rn)
The AlphaGUARD simultaneously measures and records ambient temperature, relative humidity and atmospheric pressure with embedded sensors. High responsiveness and an easy-to-read digital display make AlphaGUARD suitable to perform radon in air measurement and analysis everywhere from a lab to the field.
Mineral oil extraction of radon from water coupled with alpha/beta discrimination counting using a Quantulus 1220 LSA enables accurate determination of Radon-222 in water.
