Networked Geiger-Counter Cellphone System to Detect Radioactive Bombs

This anti-terrorism concept from researchers at Purdue University puts together miniature radiation counters built right into cellphones across the US. Each solid-state sensor would be able to sniff out radioactive sources from up to 15 feet, and then would send in the location to Homeland Security, the FBI and Jack… »1/24/08 9:25am1/24/08 9:25am
