Radiological Safety Training for Uranium Facilities
Module 104 Internal Dose Control
i. Protective Clothing
Use of protective clothing (PC) in contaminated areas will minimize
the potential for skin contamination and ingestion of uranium. The
choice of PC garments will be based on the type of job and the form of
contamination hazards. Protective clothing should not be worn in
uncontrolled areas such as lunch rooms.
Protective clothing commonly worn in the nuclear industry can also
provide beta dose reduction. Gloves are especially helpful in reducing
beta dose to the hands while handling uranium.
Contamination build-up inside work gloves has lead to unacceptable
hand doses in some facilities. Reuse of leather or cloth gloves should
be reviewed carefully because of such buildup. Workers should wear
thin, protective gloves inside the heavy gloves.
ii. Respiratory Protection
Respiratory protection equipment is used to provide protection from
airborne hazards that may be encountered in the work environment.
Respirator use is based on the level of airborne contamination known
to exist or expected to be produced from the work to be performed.
Respiratory protection may also be required for hazards present in an
area other than radioactive airborne contamination. Health and safety
groups should coordinate the use of respiratory protection
requirements based on all hazards present. If a worker finds a conflict
