The Targeting Radon Daughter and Radon Monitor (TRDRM™) is a microprocessor-based radiation monitoring system that was developed by Radiation Detection Systems (RDS) for the monitoring of the potential alpha energy concentration (PAEC) of radon daughters and the radon activity concentration (RnAC) in air, in parallel with the monitoring of the wind direction and velocity.
The TRDRM is an ideal radon and radon daughter monitor designed for a more straightforward and accurate estimate of the impact of a uranium mining project on a critical group of the public, as it measures figures that relate to radon released from the project.
The TRDRM is an ideal tool for an underground uranium mine ventilation department: ventilation can be optimised more accurately based on the monitored radon equilibrium factor, PAEC, RnAC and air-flow velocity.
The TRDRM also improves the quality of any environmental radiation research into the behaviour, origin and fate of radon and radon decay products.
The TRDRM can continuously monitor and log data into the microcontroller memory for about 3 months at a 10-minute logging interval. With a 60-minute logging interval, the system can continuously gather data for about 1.5 years. Data logs are downloaded through MS Windows / Hyperterminal and open in Excel — no special software is required for the data download.
Alternatively, data can be downloaded remotely through an optional radio and/or mobile modem.
