Our specialist RPAs Matt Brodie and Rory Jamieson conducted a survey of radon levels at the Northern UK-Based mine.
Using a Pylon AB5 monitor, they measured radon concentrations in five underground work areas.
Data collected on the day was compared with measurements taken from passive detectors and an AlphaE radon monitor to provide a floating mean (or average) of the concentrations of radon in the air over the working day.
This helped verify the AlphaE’s suitability to provide accurate readings.
The survey also explored whether radon concentrations in various work areas fell to acceptable levels within a one-hour period of the forced ventilation systems being turned on.
The survey data helped guide ARPS when making recommendations on keeping workforce exposure to radon as low as reasonably possible.
