Laboratory measurements of electro-osmotic pulsing technology in reducing radon soil gas diffusion through a concrete slab

This paper presents the experimental results of utilizing Electro-Osmotic Pulsing Technology toreduce the diffusion of radon soil gas through a concrete slab. A laboratory system with state-of-theartinstrumentation has been used to measure the diffusion coefficient of radon soil gas through 30.5cm diameter, 10.2 cm thick standard composition concrete samples (w/c = 0.5 and cement:sand:gravel= 1:2:4). Within these concrete samples, a triple titanium anode configuration is embedded while anexternal copper rod is used as the cathode.
