Slide the shutter to each position to make sure it functions properly.
2.
Visually inspect the shutter, ensuring it has not been damaged and that
all of the lead plates are in place.
Complete a tag and label check every six months. All labels and tags
attached to the source must be visible per radiation safety standards. All
labels and tags must be securely attached and legible (including engraved
labeling). Immediately replace any label that is damaged, illegible, or not
securely attached.
Do NOT paint or overcoat the source housing without first masking the
radiation identification tag and other labeling.
Below are examples of the tags and labels that may be a part of your system.
