Student's Guide
Respirators can provide adequate protection
for workers in an airborne radioactivity
environment, but engineered controls may be
more practical. By using engineered controls
instead of respirators, the worker is not
subjected to the stresses created by wearing
a respirator. It is more difficult to breath and
communicate when wearing a respirator.
Vision is impaired, and the respirator is not
comfortable. Productivity can therefore be
improved by using engineered features
instead of respirators.
To minimize intakes of radioactive material
by personnel, smoking, eating, or chewing
shall not be permitted in Contamination, High
Contamination, Airborne Radioactivity Areas,
or Radiological Buffer Areas established for
contamination control purposes.
Contamination should be contained at its
source. The principle is to prevent
contamination spread from occurring. The
most effective methods based on sound
ALARA principles should be used. All
controls should be documented and clearly
controlled by RWPs.
Respirators may be appropriate for simple,
straightforward jobs.
In specific situations the use of respiratory
protection may be contraindicated due to
physical limitations or the potential for
significantly increased external dose.
