| Title | Agreement State Report - Damage to Radiography Guide Tube Preventing Retraction of Source |
| Event Description | The following information was received from the Ohio Department of Health via E-mail:
On 6/17/2019, the licensee reported an incident while shooting at a client location in Bremen, Ohio. They were setting up 2 inch welds on a table in the shooting vault. The spool piece weighed approximately 40 pounds. As the radiographer cranked out the shot at approximately 1130 EDT, he immediately heard a loud noise and tried to crank the shot in, but could not get the source (Ir-192; 63.8 Curies) back into the camera. The vault door was opened slightly to see what had happened. The spool piece had fallen off the table and crushed the guide tube. The door to the vault was shut and licensee staff prepared a plan to get the source back into the camera. The RSO [Radiation Safety Officer] made a 15 second trip into the vault to shield the source using (6) 1 inch long x 2 inch thick x 4 inch wide lead blocks. During this first entry into the vault to put the shielding down, the RSO received a dose of 20 mR. The RSO made a second trip into the vault to put more shielding down and access the situation. During this time he discovered that the drive cable was partially sheared off and the guide tube was crimped at that area. The RSO received an additional 10 mR during this trip. With the shielding in place the licensee measured approximately 0.5 mR/hr outside the shooting vault. Proper source retrieval procedures were followed and the source was retrieved and placed into the camera using source retrieval equipment and new cranks and guide tubes. The Ohio Department of Health, Bureau of Environmental Health and Radiation Protection was contacted by phone at approximately 1430 EDT on 6/17/2019, to inform of what transpired. At no time were there any members of the public exposed. During the whole retrieval process the RSO received a total dose of 55 mR. Ohio Item Number: OH190008 |
