Student's Guide
3. Only when engineered and administrative
controls have been applied and the potential
for airborne radioactivity still exists, should
personnel protective equipment, including
use of respiratory protection, be considered.
Chapter 3 of DOE-STD-1098-99 discusses:
Access controls for Contamination Areas
Controlling the spread of contamination
Monitoring for contamination.
Appendix 3 C, Contamination Control
Practices, includes recommended selection
of protective clothing, and a recommended
sequence for donning and doffing.
Use of respiratory protection should be
considered under the following conditions:
Entry into posted Airborne Radioactivity
Areas
During breach of contaminated systems
or components
Work in areas or on equipment with
removable contamination levels greater
than 100 times the values in Table 2-2 of
DOE-STD-1098-99
During work on contaminated or activated
surfaces with the potential to generate
airborne radioactivity
The selection of respiratory protection
equipment should include consideration of
worker safety, comfort, and efficiency. The
use of positive pressure respiratory
protection devices is recommended wherever
practicable to alleviate fatigue and increase
comfort.
