Dr. Dai is a Co-PI of a 4-year grant ($1.2 million) building a novel large-scale radon measurement wireless testbeds funded by the U.S. National Science Foundation

This research will design a real-time wireless radon measurement sensor test-bed that will constitute a 200 node sensor network to be deployed in Atlanta. The testbed will measure and study soil radon penetration, distribution and movements of radon in surficial soil from 200 locations in the testbed site, along with temporally and spatially variable parameters.

We will develop a real-time web GIS system to build radon prediction models that map radon distributions along space and time.
