Cornell Tech researchers have developed a portable device called SoilScanner that uses radio frequency signals and machine learning to detect lead contamination in soil. It offers a cost-effective alternative to traditional methods of testing that "generally involves either sending samples to a lab for analysis, which relies upon harsh chemicals and can be expensive, or using a portable X-ray fluorescence device," notes Phys.org. From the report:"In recent years, especially during COVID, a lot of us got excited about having our own backyard garden, or spending more time at home," said [Rajalakshmi Nandakumar, assistant professor at the Jacobs Technion-Cornell Institute at Cornell Tech] who's also a member of the Department of Information Science in the Cornell Ann S. Bowers College of Computing and Information Science.
