The Networked Radiation Detection System and Personal Safety Device concept was generated over a four-day period and intended for entry into the July 2004 Popular Science/Core77 "Security" Design Competition. This was, essentially, a design for a "blogject" before that word was coined. The device is intended to be part of a larger system which depends upon user participation to ensure the safety of all. It does this by effectively turning the people who wear these devices into network sensors; doing in the real world what is increasingly now being done in the online world: aggregating individual input to benefit for the group.
