Radiological Exposure Devices (REDs)
Radiological Exposure Devices (REDs) = Hidden Sealed Radioactive Source
- Definition of Radiological Exposure Device
- Causes exposure (Animations) but NOT usually contamination
- Example: hiding a hidden radioactive source on a subway or in a sports arena, where people would unknowingly receive radiation exposure (See Figure 1)
- Exposure dose and specific effect on people would depend on
- Source properties: isotope, activity, amount
- Proximity of each person to the source
- Length of time people were in proximity to the source
- Whether a person's whole body or only a portion of the body received exposure

Ci = Curie; R = Roentgen; Γ constant = 4.69 R-cm2/mCi-hr.
