| Title | Agreement State Report - Leaking Nickel 63 Source |
| Event Description | The following information was received via email:
Operations Manager of National Technical Systems, NTS- Silicon Valley, contacted RHB [California - Radiation Health Branch] Sacramento and reported that their analytical equipment, manufactured by Particle Measuring Systems, used for analyzing gases by ionizing them with a 10 milliCi Nickel-63 source was leaking. The Nickle-63 source leakage was discovered in their recent leak test that was performed in anticipation of shipping the unit to the calibration lab. This resulted in a reading well above the 11,000 DPM limits (it was 4.8 million DPM inside the outflow fitting of the equipment). National Technical Systems shipped the detector cell and equipment to Particle Measuring Systems for disposal. National Technical Systems conducted surveys in the area where the unit was stored and used, and no Nickel-63 contamination was found. According to the radiation safety officer of Particle Measuring Systems, the contamination was contained inside the outflow part of the equipment. Equipment Manufacturer: Particle Measuring Systems; Equipment Name and Model: Air Sentry II, Chlorides Monitor Based upon disposal and appropriate surveys, this item is closed. |
