EN Revision Text: DAMAGED INSTROTEK MOISTURE DENSITY GAUGE
The following is a summary of a phone call with the licensee:
On 7/30/2021 while at the jobsite in Moca, Puerto Rico, the licensee's InstroTek MC-3 Elite gauge was run over by a paving roller while in the safety drum. The gauge plastic casing was damaged and the source rod was broken. The sources were in the shielded position at the time of the incident. The InstroTek gauge serial number is 31331 and contains nominally 10 mCi of Cs-137 and 50 mCi of AmBe.
The damaged gauge was placed in its storage container and returned to the licensee's Cabo Rojo facility for a swipe test. After the incident, the gauge read 0.2 to 0.3 mR/hr at 1 meter with a survey meter.
No overexposures were reported.
* * * RETRACTION ON 8/3/21 AT 1320 EDT FROM ALFONSO BOSQUE TO KERBY SCALES * * *
The following retraction is a summary of a phone call with the licensee:
The Radiation Safety Officer inspected the gauge and verified that the gauge maintained its safety function. The source was secured and a leak test verified no leakage.
