ENS 40304 | 7 November 2003 17:44:00 | Licensee reported via phone call of potential overexposure of two employees to carbon-14. The licensee indicated initial calculations showed approximately 2.5 Rem exposure. Licensee followed up the phone call on November 7, 2003, after receiving urinalysis results. The initial calculations indicated internal whole body exposure to carbon-14 of 7976 milli Rem and 8976 milli Rem for two employees. The 252 milliCuries carbon-14 was in a mixture of 221 micro liter benzene in a flame sealed glass ampoule which was being readied for shipment to a customer. The ampoule was wiped for contamination and placed on a counter outside of the fume hood for approximately 2 hours. Initially the ampoule was thought to be in the fume hood. The ampoule was found to be leaking and 59 milliCuries of carbon-14 remained in the ampoule. The resultant loss into the lab was 193 milliCuries of carbon-14. This is a preliminary report to be updated as information is received. Person 1 received 7.976 Rem internal (CEDE) occupational. Person 2 received 8.976 Rem internal (CEDE) occupational. |
ENS 40638 | 3 April 2004 13:56:00 | Dressler Consulting reported to the Kansas Department of Health and Environment that a trusted employee failed to show up at his worksite at 634 Prospect, Kansas City, MO this morning. Dressler Consulting is located in Shawnee Mission, KS. The employee had in his possession a Humboldt Moisture Density Gauge, Model 5000, Serial Number 2655 which had a 10 millicuries Cs-137 and 40 millicuries Am-241source. Dressler Consulting also notified the local law enforcement, Raytown Police Department, and the MO Department of Health. The gauge is normally restrained with a 2000# tow strap and locks in the employee's truck. The employee was told to store the gauge inside his home overnight. A Dressler Consulting representative attempted to contact the employee on telephone and went to his apartment in Raytown, MO with negative results. The employee last contacted Dressler Consulting at 1700 CST on 4/2/04 when he finished a job at 6700 Agnes, Kansas City, MO.
Dressler Consulting reported that the driver was contacted by his sister on his personal cell phone. His truck is broken down between Saint Louis and Kansas City, MO. The gauge is not in the truck. The driver will be contacted again to determine the location of the gauge. Notified NMSS (Moore) and R4DO (Powers)
Dressler Consulting reported that the gauge was found in the employees apartment and is no longer considered missing. The protocol for handling and storing gauges will be reviewed by the licensee. Notified NMSS (L. Psyk) and R4DO (B. Spitzberg). |
ENS 43019 | 1 December 2006 16:55:00 | The licensee reported a lost static air gun containing 10 millicuries of Po-210. The source is approximately 1 year old and the licensee believes the source was disposed of while attached to an air hose which was thrown away. The State is continuing its investigation into this event and will provide updated information when it is available. THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks. |
ENS 43596 | 25 August 2007 09:55:00 | A representative from the State of Kansas contacted the NRC Operations Center to report a stuck radiography source. The source is stuck at Chanute Manufacturing Shop, 1700 South Washington Street, Chanute, Kansas. The company has a radiography shop and was performing a radiography shot of a drum when the guide tube stand fell approximately 2 feet and kinked the guide tube while retracting the source. The camera is an Amersham Model 880 with less than 100 Curies of Ir-192. The licensee reports the source is "stuck good". A 1 Mr/hr boundary has been established, and the area is secured. The state is unsure how far the source is from its fully retracted storage location. The licensee is attempting to locate a recovery team, and the State of Kansas is requesting assistance in locating a recovery team. At 1110 EDT, the State of Kansas called back to report that the licensee has made arrangements with QSA Global of Boston, MA to come to the site today and recover the source.
QSA arrived on 08/25/07 and completed recovery operations at 2017 CDT on 08/25/07. Highest dose received by a QSA person during recovery operations was 50 millirems as measured by an ion chamber detector. R4DO (R. Nease) and FSME (C. Flannery) notified. |
ENS 50050 | 23 April 2014 09:46:00 | The following was received from the State of Kansas via fax: Today (on) 4/22/14, (the) x-ray radiography crew had a source hang-up, at the NCRA plant in McPherson, Kansas, at approximately 0930 CDT. (The) radiography crew performed their operational and emergency procedures very well. A 35 curie Ir-192 source hung up in the source guide tube. (The crew) made the necessary adjustments to their boundaries, kept watch over them, allowed no one to enter, notified (the crew supervisor) and the Kansas RSO. They re-adjusted the crankouts and pulled them to straighten out the cranks and guide tube, and were able to retract the source into the device with one attempt, and were successful. There was no disconnect or anyone exposed to radiation levels above regulatory limits. Notification of the incident was given to the plant safety coordinators at the time of the incident, and they remained at distance to avoid exposure, the full time of the incident lasted approximately 10-15 minutes from the initial determination of a stuck source to retraction of the source into the device. Three monitored IRISNDT staff were onsite and they watched over the boundaries while the retraction was completed. After the incident, all IRISNDT staff read their Instadose film badges and got readings from their personal dosimeters ranging from 1.2 to 3.8 mRem. Kansas incident # KS140007 |
