F.
Primary Reasons for Contamination Control
1.
Protection of the worker
Measures to control radioactive contamination are
implemented to protect workers by:
o
Minimizing the chance of inhalation or
ingestion of radioactive/hazardous material.
o
Eliminating or reducing external radiation dose
rates.
o
Reducing worker discomfort by minimizing the
use of personal protective clothing and/or
respirators.
2.
Radioactive materials may enter the body by:
o
Inhalation (the most common pathway).
o
Cuts/wounds (i.e., sharp instrument punctures).
o
Absorption (skin, mucous membranes, eyes).
o
Ingestion (biting nails, applying cosmetics,
eating, drinking, or smoking either in the lab or
outside without monitoring or washing hands).
