| Title | Agreement State Report - Potential Radiation Worker Overexposure |
| Event Description | The following was received from New York via email:
Possible [overexposure] event occurred when a radiochemist employed by Weill Cornell Medical College recorded an exposure of 1675 mRem during the October 1-October 31 monitoring period. This caused his year to date exposure for the year 2015 to exceed the annual maximum permissible personnel exposure of 5000 mRem per year. His year to date dose equivalent through October 31, 2015 is 5546 mRem. The radiochemist synthesizes radiopharmaceuticals for PET and PET/CT. He works primarily with Carbon-11 with a 511 keV gamma energy. Investigation was performed by the licensee [New York Presbyterian Hospital]. They analyzed his workload, procedure methods and the quantities of the radiopharmaceuticals he worked with in October and confirmed that it did not vary from previous months in this year. Also other radiochemists working with him did not receive any elevated exposures nor were there any contaminations in the radiochemistry area. Since the radiochemist October exposure was 43 percent of what he had received in his previous 9 months, the licensee concluded that the dosimeter may have been accidentally contaminated. The investigation concluded that the radiochemist did not receive an overexposure of 1675 mRem. New York Incident # NY150008 |
