]Another invention that merited the Discover award was a land-mine detection device crafted by researchers at the U.S. Pacific Northwest Laboratories. It looks like a weed trimmer used by many landscapers to cut grass. But this device is equipped with a sensor that uses small amount of radioactive material to detect the presence of hydrogen — a common element in land-mine explosives.Petranek notes that it can even find mines made of hard-to-detect plastic. And with an estimated 110 million land mines buried worldwide, “this will save the more than 70 people a day who are dying from land mines,” he said. All 2001 Innovation Award honorees received $5,000 for their inventions and will be featured in the July issue of Discover. But Pacific Northwest Labs’ mine detector also got the nod — and $10,000 — from the Christopher Columbus Fellowship Foundation, an independent federal government agency established to encourage and support new discoveries.
