[Licensee employee] called RSO to let him know that [a radiographer trainer] had 12.5 rem deep dose equivalent for Quarter 3 - July 1-31, 2005.
On Wednesday, 8/10/05, [name deleted], RSO for Turner Industries called DSHS Radiation Control (RC) to report that [licensee employee] has informed him that [name deleted] radiographer trainer for his company, had a 12.5 rem deep dose equivalent reading for Quarter 3-July 1-31, 2005 monitoring period.
[The radiographer trainer] wrote a statement to RC stating that he has worked as an x-ray radiographer for the last 6 years with Turner Industries, is very conscientious & checks his dosimeter often throughout the work day. He stated that he was closely supervised by the RSO for the monitoring period in question & did training for a new trainee.
An on-site investigation was conducted by [name deleted], a RAM inspector for RC. [The RAM inspector] interviewed [the radiographer trainer] & [another employee] regarding this investigation. Both [the radiographer trainer and the other employee] felt that this was a result of an altercation [the radiographer trainer] had with a contract radiographer & felt that this was the result of a retaliation against [the radiographer trainer] for not allowing the contract radiographer to enter [the radiographer trainer's] shooting bay. [The radiographer trainer] went on vacation & from 6/27-07/5/05.The RSO & [the radiographer trainer] felt that the contract radiographer had access to [the radiographer trainer's] film badge & a radiography camera & could have easily carried out this retaliation without being noticed.
The RC inspector reviewed past monitoring records for [the radiographer trainer] & found that his results were consistent with someone receiving 50-60 mrem /month & 500-650 mrem/year in this line of work. The inspector concluded that the overexposure appeared to be very suspicious & agreed that the overexposure be readjusted to reflect the normal monthly results for [the radiographer trainer].
Additional Documents Supplied:
Personnel monitoring records for the past year for [the radiographer trainer] were obtained & sent in to RC by the RAM inspector. The investigation determined that the dose appeared to be to the dosimeter only. No violation recommended. RC has issued a letter concurring with the licensee's investigation results & has sent a copy of this letter to DSHS RC.
