Staff Sgt. Hannah Dickerson checks her emergency dosimeter

Staff Sgt. Hannah Dickerson checks her emergency dosimeter for radioactive contamination during a Global Dragon training event on March 18, 2015. The dosimeter monitors cumulative exposure to radioactive materials, and will sound an alarm if the wearer is too close to a dangerous area. Held at the Guardian Centers of Georgia, Global Dragon Deployment For Training provides a refresher course for Airmen, allowing them to put their skills to use to identify live chemical, biological, radiological and nuclear agents and materials. Air National Guard emergency management technicians from more than 20 individual units participated in Global Dragon. (New York Air National Guard / Staff Sgt. Christopher S. Muncy / released)
