I.
RADIOLOGICAL CONTAMINATION
EO1
DISTINGUISH between ionizing radiation and radioactive contamination.
A.
Comparison of Radiation and Radioactive Contamination
Radioactive contamination is radioactive materials where you do not want it.
Recall that radioactive material is material that contains unstable "radioactive" atoms.
Even when this radioactive material is properly contained, it still emits radiation and may
be an external dose hazard, but it will not be a contamination hazard. When radioactive
material is inadvertently released from its container (e.g., a spill), it is then referred to as
radioactive contamination.
Radiation is energy, contamination is a material. Exposure to radiation does NOT result
in contamination.
B.
Types of Contamination
EO2
DEFINE fixed, removable and airborne contamination.
Contamination can be grouped into 3 types:
o
Fixed.
o
Removable/transferable.
o
Airborne.
1.
Fixed contamination
Fixed contamination is contamination that cannot be readily removed from surfaces.
o
It cannot be removed by casual contact, wiping, brushing, or washing.
