New device's radio waves reveal lead contamination in soil

Summary

A Cornell Tech-led research group is developing a portable, inexpensive device that uses radio frequency signals to measure lead contamination levels in soil.

SoilScanner sends radio waves of different frequencies from an RF transmitter, through a soil sample to an RF receiver, which reveals the effect the soil—and how much lead is in it—has on the signal.

The team is also working on an even smaller, less costly, battery-operated version of the device.
