On December 7, 2004 at noon, the [Radiation Safety Officer]
RSO contacted the [State of
California Radiological Health Branch] Office to report a nuclear density
gauge (
Troxler model 3440, serial #15945) with a nominal 40 mCi Am:Be source (serial #47-11302) and a nominal 8 mCi
Cs-137 source (serial #50-4969) had been
stolen out of a locked construction trailer at Blossom Housing site off of Flynn Springs Road in the County of San Diego sometime between 11 am on Monday, December 6, 2004 and 7 am on December 7, 2004, when the theft was discovered. The
gauge was last seen by the
gauge user when he locked it up on Friday [12/03/04] at 3:30 pm in a trailer owned and used only by Geocon, Inc. A job foreman with another company reported he had noticed the trailer was locked shortly before he left the job site on Monday, December 6, 2004 at 11 am. Besides being inside the locked trailer, the case containing the
gauge was locked with a padlock and the case was chained and locked to the trailer. The dead bolt lock on the trailer door had been drilled out and the
gauge,
gauge case, chain and lock, along with the door lock had been removed from the premises. A police report was filed with the San Diego County Sheriff's office (case #04084256A).
A reward will be offered for the return of the nuclear gauge.
The FBI was apparently informed of the theft by the San Diego Sheriff's office, as the licensee reported receiving a call from the FBI.
The
California report number for this event is 120704.
