RCP staff evaluated NRC reporting requirements. Equipment was secured on-site. No loose contamination identified and maximum dose rate was 20 mR per hour at contact on the shielded source holder. No personnel exposure and there was no immediate threat to public health. No additional emergency response was required. RCP personnel assisted in boxing the damaged gauge and the licensee will return the gauge securely to their office and will then arrange for transport back to the manufacturer. RCP will follow up with additional information. | RCP staff evaluated NRC reporting requirements. Equipment was secured on-site.

Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks.
