If a gauge is damaged, then follow the steps below:
✓ Locate the gauge and/or source.
✓ Do not touch or move the gauge.
✓ Immediately cordon off an area around the nuclear gauge and/or
source. A radius of 15 ft (5 m) will be sufficient. Do not leave
the area unattended.
✓ Keep all unauthorized personnel from the nuclear gauge.
✓ If a vehicle is involved, it must be stopped until the extent of
contamination, if any, can be established.
✓ The gauge user should perform a visual inspection of the
nuclear gauge to determine if the source housing and/or
shielding has been damaged.
✓ Use a survey meter to measure the dose rate at a distance of 3 ft
(1 m) from the gauge.
✓ Contact the company RSO (name and number given at the
beginning of this section). Provide the RSO with the following:
♦ The date, time, and location of the accident
♦ The gauge model and serial number
♦ The nature of the accident
♦ The location and condition of the gauge and/or source
♦ The dose rate at 3 ft (1 m) from the gauge
