Radiological Safety Training for Uranium Facilities
Module 104 Internal Dose Control
an evaluation of activities likely to generate or spread contamination,
use of containment devices to confine contamination as close to the source
control and monitoring of airborne contamination as it is generated,
minimizing the size and number of contaminated areas by using effective
control of movement of equipment and personnel into and out of
use of personal protective equipment, and
effective contamination monitoring.
Evaluation of Work Activities
Work activities that involve the destruction of surfaces, such as grinding,
machining, filing, or cutting, can easily create and spread contamination.
Operations such as welding, burning, heating, etc. can alter the physical
and/or chemical state of uranium compounds that are on the surfaces of
equipment. Work activities such as these should be evaluated and steps
taken to minimize the spread of surface contamination, personnel
contamination, and airborne contamination. If possible, alternative
methods for completing the task should be considered.
Use of Containment Devices
Whenever activities that may generate loose contamination are planned,
consideration should be given to using containment devices to control the
contamination to an area as close to the source as possible. Such devices
include glovebags, gloveboxes, and tents.
