We are excited to announce a new case study titled "Monitoring Thoron in the Presence of Radon to Locate Terrestrial Sources of Pollution in Thailand Waterways". The case study describes a research project, led by Professor Emeritus William Burnett, to identify sources of pollutants entering key waterways in Thailand, the world's largest exporter of farmed shrimp. By leveraging the DURRIDGE RAD7's unique capability to measure both radon and thoron independently, locations of surface groundwater discharge (SGD) were able to be pinpointed and identified as sources of polluted groundwater entering the canals. The results of this research are sure to spur further studies and improvements to maintain Thailand's globally important shrimp farming industry.

A lack of ventilation in multi-unit dwellings can affect human health adversely, owing to accumulated radon gases; therefore, developing immediate and effective methods to reduce radon gas in indoor living environments is urgently needed. This study conducted basic research to develop ventilation guidelines for radon through assessments of various ventilation strategies on indoor radon concentration in multiple-unit dwellings, a typical residential type in Korea.

DURRIDGE maintains two certified calibration systems, one at headquarters in Billerica, MA and another at our R&D facility at Durridge UK in Sheffield, England. The systems are compared, to a precision of better than 1%, with a secondary standard chamber, which is in turn calibrated by comparison with a NIST radon standard supplied through the U.S. EPA. The calibration process is monitored by sophisticated software developed and continuously updated by DURRIDGE.
DURRIDGE Tip
The RAD7 radon monitor works most effectively when the incoming air sample has a low relative humidity. The DURRIDGE DRYSTIK Model ADS-3R transfers moisture from the incoming air to the air being pumped out of the RAD7. As the air enters the RAD7, it will have already lost most of its moisture, greatly extending the life of the desiccant in the drying unit. In certain cases the need for desiccant is eliminated altogether.
