| Title | Agreement State Report- Potential Rad Worker Overexposure |
| Event Description | The following report was provided by the Tennessee Division of Radiological Health via email:
At approximately 2105 [EDT] on the night of July 12th, using our local access control program (i.e., Canberra HIS20) and a DMC 3000 series electronic dosimeter, an Erwin Resin Solutions employee was exiting the Radiological Controlled Area when he received a message stating that he had exceeded his TEDE [Total Effective Dose Equivalent] limit. According to the access control program, a dose of 10002.2 mrem was received. The employee was immediately removed from the area and follow up surveys were conducted. Surveys indicated that general area dose rates were 2-15 mr/hr and that the highest individual package dose rate was 45 mr/hr. The individual had been in the area for approximately 0.47 hours5.439815e-4 days <br />0.0131 hours <br />7.771164e-5 weeks <br />1.78835e-5 months <br /> and he recalls at one point looking down at his dosimeter to see a display of 2.4 mrem. The employee's TLD has been pulled and sent off to Mirion for an emergency read, results are expected within 24-48 hrs. The individual will remain out of the RCA until the investigation has concluded. Access records have been pulled from the HIS20 program and the doses given were not reflective of a normal entry. A START READ of 0 mrem was given and an END READ of 0 mrem was also given. A GAMMA COMPONENT READ of 10002.2 mrem was given but should have been the same as the END READ which was 0 mrem. All indicators lead to a faulty electronic dosimeter, the dosimeter in question is being sent to our instrument department for further evaluation. Tennessee Event Report ID No.: TN-15-101 |
