| ENS 50435 | 8 September 2014 20:00:00 | Agreement State | Agreement State Report - Contaminated Cd-109 Sealed Source | The following information was obtained from the Commonwealth of Massachusetts via email: The Agency (Massachusetts Radiation Control Program) was notified on 9/8/2014, by Thermo Scientific Portable Analytical Instruments, Inc. (MA RAM License # 55-0238), that a leak test result for a Cd -109 sealed source was above the leak test limits of 185 Bq (0.005 microCi). The wipe test showed that the removable activity was 486 Bq (0.0131 microCi), which is above the regulatory limit. The licensee provided the following information about the sealed source: The source manufacturer is Eckert and Ziegler (formerly/aka Isotope Products Laboratories). The model number is FXB-3 and intended for use in a handheld XRF analyzer. Total activity on the source is 40 mCi. The wipe test was done in a controlled environment in their production source room as they were taking the source out of its original packing material. The licensee did survey the area after discovering the wipe test and did not find any signs of contamination elsewhere. The package (not the sources within) was received on August 21, 2014 and wipe tested clean at that time, so there is no indication that contamination has spread anywhere beyond the source itself. There were no personnel contaminations or area contamination from this contaminated sealed source. The licensee will file a report to our agency within 5 days of this leak test. The Agency considers this matter to still be OPEN pending further review of this event. |
