The monitor was tested under constant and rapidly fluctuating radiation conditions. Experimental data obtained with the monitor were compared with data obtained by conventional grab-sampling and with an automated radon daughter/thoron daughter 'grab-sampler'. The Working Level used in the tests ranged ...
Monitor air quality and safeguard your health with SunRADON's trusted continuous radon monitors for professionals, inspectors, and homeowners worldwide.
An environmental radon daughter monitor has been designed and tested under laboratory controlled conditions in a large radon/thoron test facility (26 m3) and in an underground uranium mine. The monitor operates on continuous sampling and time integrating principles. It has been tested under constant ...
The lower level limit detection of this monitor is 0.48 Bq m-3 (EEC) for 1h interval. Comparison experiments were carried out in the radon chamber at the National Institute of Metrology of China. The measurement results of this SAF monitor are consistent with EQF3220 (SARAD GmbH, Germany),...
An evaluation of a radon daughter monitor was carried out in an underground uranium mine. The monitor operates on continuous sampling and time integrating principles. Experimental and theoretical data were compared. Experimental results show that the monitor underestimates the Working Level, a fact ...
Radon fluxesSurface and pore waterSankarabarani river basin gains importance due to agriculture, an industrial and recreational activity that delivers large groundwater fluxes to the Bay. Attempt has been made by continuous monitoring of radon isotopes to evaluate submarine groundwater discharge with ...
The activity concentration of supported radon in water sample was measured using continuous radon monitor inside the radon chamber. Measurement was carried out at one hour interval for twenty four hours. The hourly supported radon concentration was found to stabilize after about 8 hours. The ...
