| OVEREXPOSURE TO GAMMA RADIATION |
| |
| The following is taken from a facsimile report: |
| |
| "A radiographer was [radiographing] welds on a vessel shooting with a 35 |
| curie Co-60 source and entered the vessel to change the source location |
| without cranking the source into the shielded position. The radiographer has |
| been taken for blood samples which will be repeated in 72 hours. Initial |
| calculations indicate a possible whole body exposure of 70 rems. Further |
| information forthcoming after investigation scheduled for May 14." |

| SHUTTER FAILED TO OPEN ON A DMC/RADIOMETRIE GAUGE. |
| |
| A DMC/Radiometrie Model E6 source housing shutter failed to open. The |
| licensee swapped out the housing and will send the defective housing back to |
| Radiometrie, located in Gaithersburg, MD. The DMC/Radiometrie Model E6 |
| gauge contains one curie of Americium-241 which is used to measure the |
| thickness of thin sheets of steel. Bethlehem Steel Company has 30 or 40 of |
| these in the plant and this is the first time that a shutter on one of these |
| gauges has failed to open. The licensee stated that they have had these |
| gauges since the 1970's. |

| CONTROL ROOM VENTILATION SYSTEM INOPERABLE |
| |
| "At 1835 on 4/10/02, the Control Room Emergency Ventilation system |
