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?
