| ENS 45177 | 30 June 2009 04:00:00 | Agreement State | Agreement State Report - Safety Function Failure | The following information was received via facsimile: The electronics are not working on a (thickness) gauge on the Z-34 press. The equipment is out of use. The (Integrated Industrial Systems) gauge (is a Model #SS-3A) with a serial number (of) #9834LX; 1000 milliCurie Am-241. A potential cause is the source moved. The licensed contractor RSI (Radiometric Services and Instruments) was contacted to fix the thickness gauge. A Commonwealth of Massachusetts investigation is pending. | ||
| ENS 45096 | 26 May 2009 04:00:00 | Agreement State | Agreement State Report - Gauge Shutter Stuck Open | The following was received from the State of Massachusetts via fax: A gauge on the Z-24 press is sometimes stuck open. The equipment is out of use. A licensed contractor was contacted to fix the gauge. Gauge s/n Z3239, model number SS-3a. Radionuclide is 1000 mCi of Am-241. | ||
| ENS 43954 | 1 February 2008 18:00:00 | Agreement State | Agreement State Report of Metal Thickness Gauge Malfunction | The Massachusetts Radiation Control Program (MRCP) reported that a licensee, Allegheny Rodney (metal foil manufacturer), informed the MRCP of a malfunction in a metal thickness measuring gauge. The process gauge is supplied by Integrated Industrial Systems and contains a 1000 milliCurie Am-241source (Serial #1225). The licensee stated that the gauge is not functioning for unknown reasons and a technician from Integrated Industrial Systems will be responding to investigate the problem. There is no evidence at this time of a missing or leaking source. MRCP intends to follow-up with the licensee early next week after the cause of the gauge malfunction has been determined. | ||

Description: Thickness gauge Investigation Pending: No Consultant Hired: Yes Corrective Action: Licensed Contractor fixed the gauge SUBJECT: A gauge on the Z-25 press is sometimes stuck closed. The equipment is out of use. Equipment problem : Shutter was not working properly. Equipment problem, capacitor fell off. | ||
| ENS 43297 | 10 April 2007 04:00:00 | Agreement State | Agreement State Report - Malfunctioning Gauge Shutter | The State provided the following information via facsimile: The licensee uses a Themo Electron Model SR-U2 device, no serial number provided, to measure thickness. The device contains a Sr-90 50 millicurie source. On 04/10/07, the licensee left a phone message that the gauge shutter stuck closed (Different gauge than reported in EN #43296). A contractor has been called to fix the gauge. | ||
| ENS 43296 | 27 March 2007 04:00:00 | Agreement State | Agreement State Report - Malfunctioning Shutter | The State provided the following information via facsimile: The licensee uses a Themo Electron Model SR-U2 device, serial number 1179BC, to measure thickness. The device contains a Sr-90 50 millicurie source. On 03/27/07 the gauge shutter stuck open. The unit was secured by restricting access to the one door that leads to the area where the gauge is located. The gauge vendor has been called. On 03/30/07, a contractor, RSI, came in to repair the broken spring on the gauge. | ||
| ENS 40872 | 13 July 2004 14:30:00 | Agreement State | Agreement State Report from the Commonwealth of Massachusetts | Thermal Electron found a torn window on a DMC Thickness measurement gauge while performing preventative maintenance on the gauge. The DMC thickness measurement gauge is licensed to Allegheny Rodney which is located in New Bedford, MA. The model number for the DMC measurement gauge is SR-U2. The serial number for the gauge is J3013T. The gauge contains a 50 milliCurie strontium-90 source. There is no sign of contamination and there is no expected exposures at this time. The Commonwealth of MA is sending someone out on 07/15/04 to investigate this problem. |
