| ENS 54572 | 6 March 2020 15:14:00 | The following is a synopsis of information received via E-mail: At 1430 EST on 3/6/2020, the Bristol Myers Squibb Radiation Safety Officer made a notification to the New Jersey Bureau of Environmental Radiation that following the Tritium exit sign inventory for their campus, six exit signs were unaccounted for. The exit signs contained a total of approximately 130 Curies of Tritium. New Jersey State Event Report ID Number: TBD 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 54135 | 27 June 2019 09:45:00 | The following was received via e-mail: At approximately 1800 EDT on 6/25/2019, the conductivity of the underwater pool irradiator water rose to 308 microSiemens/cm and remained in this range throughout the night. This was in conjunction with low flow through the water circulation pump. The pump was repaired the morning of 6/26/2019 and subsequent conductivity readings have ranged from 24.3 microSiemens/cm to 13.9 microSiemens/cm. The licensee is currently on a plan of changing the deionization tanks every two days to continue cleaning the water. In addition they are working with a supplier on additional methods to clean the pool water. New Jersey Event Report Identification No.: INV190001-507147 |
| ENS 51926 | 13 May 2016 10:22:00 | The following information was obtained from the State of New Jersey via fax: (The New Jersey Department of Environmental Protection was informed that in Galloway Township, New Jersey), a Troxler (gauge) Model 3440, S/N 17337, was run over by the company pickup truck. This gauge contained 9 mCi of Cs-137 and 44 mCi of Am-241/Be. The gauge was not in its transport container, so the outer housing of the gauge was badly cracked and fell off. The licensee reported no release of licensed material or contamination and no overexposure. State Event Report ID No.: NJ #16-05-12-1410-12 |
| ENS 47445 | 16 November 2011 10:11:00 | The licensee's two fixed gauges were locked out because of maintenance on refractory equipment occurring the weekend of 10/22/11. On the morning of 10/24/11 it was discovered that the shutter had fallen. The exact timing of when the shutter fell is under investigation. This event resulted in a possible overexposure of members of the public. Staff from the NJDEP (New Jersey Department of Environmental Protection) is visiting the site today, 11/15/11. The gauge is a TN Technologies Model #5204, S/N B585, fixed gauge containing 8 Ci of Cs-137. NJ Incident #: 410183 |
| ENS 46911 | 2 June 2011 07:49:00 | The following information was received via fax: The licensee's portable density gauge operator was performing compaction studies with a Troxler Model 3430 on the slopes of a landfill. The source was in the locked position and the operator was present and standing about 30 feet away. A bulldozer came up over the slope and impacted the gauge. The gauge was intact except for damage to the shutter. The operator immediately contacted the RSO who responded to the site with a survey meter within minutes. Readings were within guidelines. The gauge was returned to its case, and loaded for transport. The RSO surveyed the area to check for contamination. No elevated readings were found. The gauge is in its locked storage area pending instructions from Troxler. NJ Report ID No. NJ11004
The gauge electronics and outside cover were crushed and the shutter was damaged. However the source housing and the source rod were not damaged and were intact. Notified the R1DO (Conte) and FSME (Von Till). |
| ENS 46908 | 1 June 2011 13:05:00 | The following information was received by fax: Radiographers set up a shot on a 2 inch diameter pipe which was laying in jackstands. They were working with a SPEC 150 exposure device containing a 42 Ci Iridium-192 sealed source. The jobsite was a large laydown yard in an industrial setting. The pipe fell from the stands and hit the guide tube. The guide tube was hit about 2 inches from the exposure end, and attempts at retracting the source were unsuccessful. The radiographers re-established boundaries and contacted the local (Assistant) RSO (ARSO) from the new boundary at approximately 1200 (EDT). The ARSO is authorized to perform source retrieval for JANX. (The licensee) maintained surveillance while awaiting his arrival. The ARSO arrived onsite at 1240 (EDT), assessed the situation and interviewed the crew. He noted that the source tube appeared to have 2 crimps. The ARSO was in contact with the Corporate RSO in Michigan during the operation. The ARSO used lead blankets to shield the source and surveyed. Survey revealed need for more shielding that was delivered to the site by (1345 EDT) and acceptable dose rate was achieved. He proceeded to remove the crimped section from the guide tube, observed that the drive cable was unaffected, connected the tube together with tape, and was able to retract the source into the exposure device. The event concluded by (1520 EDT). The licensee will be making a full report with corrective actions within 30 days of the occurrence. New Jersey Event: NJ 11003 |
