Radiological Dispersive Device; “Dirty Bomb”

By Dr. John Nordin, PhD

One of the most difficult training exercises for responders is how to deal with a radiological dispersive device or “dirty bomb” incident. Unlike fires, explosions, or chemical spills, there aren’t past examples where radioactive material has been actually dispersed by a terrorist where responders can learn from the experience. Furthermore, how do we even know that a radioactive material has been dispersed; if so, what radioactive material and how much? One trainer came to AristaTek and asked for a simple “widget” for converting gamma radiation counts, Curies, Becquerels, Roentgens, Rads, etc. Grays, etc. to a measure of dose, e.g. Sieverts, or Rems. The units by which radiation is measured in itself is bewildering. What are the chances of a person exposed to radiation developing cancer later in life?
