Chapter 126
During operation, make sure that the Vanta iX remains under the direct control of a
factory-trained, certified operator. Set and protect the login password for each user of
any control system.
Time, Distance, and Shielding Policies
Operators should limit the amount of time they spend around the energized Vanta iX
XRF analyzer, maximize their distance from the analyzer window, and shoot into
high-density materials whenever possible.
Preventing Exposure to Ionizing Radiation
All reasonable measures, including labeling, operator training and certification, and
the concepts of time, distance, and shielding, should be implemented to limit
radiation exposure to as low as reasonably achievable (ALARA).
1.10.2 Dosimeters
Dosimeters record accumulated radiation exposure over a specific period of time
(Figure 1-1 on page 26). Dosimeters are used to monitor individuals who work with
devices that emit ionizing radiation or who work in close proximity to someone else
working with such devices.
