| Title | Agreement State Report - Scrap Metal Contamination |
| Event Description | {{#Wiki_filter:State of California provided the following information via email:
[The] US Customs Service, Port of Oakland contacted RHB-Berkeley on the morning of 07-07-2005, reporting that a load of scrap metal bound for China had set off a radiation alarm. Mr. Kent Prendergast and Mr. Mark Gottlieb of RHB-Berkeley responded. Measurements were made of the trailer and the following readings were obtained using a Bicron FieldSPEC-N, sn 02f3/777, portable MCA: Dose Rates: Surface = 260 �R (microR)/hr; 1 foot from surface = 38 �R/hr; 1 foot to the left = 35 �R/hr; 1 foot to the right = 45 �R/hr; 1 foot above = 19 �R/hr. The radionuclide was identified as Am-241. On 07-08-2005, the Pleasant Hill Recycling Center was visited. The Port of Oakland determined that the load of scrap metal had originated there. [The Recycling Center] President and the Manager were interviewed. They stated that the load was lead scrap which had been accumulating for several years. They said that it would be very difficult to identify the source of the Am-241 if possible at all. They were uncertain if the scrap would be returned to them or handled by the Port of Oakland. [The Recycling Center President had] made contact with a health physics consultant as directed by the Port of Oakland to dispose of the Am-241. The area where the lead was stored was surveyed with both a Ludlum Model 3-98 survey meter with an external thin window, thin crystal Nal probe Mode 44-3, and a Ludlum Model 19 �R meter. The results of the survey were negative. Based on measurements and calculations performed on 7-19-05 and 7-20-05, the activity of the Am-241/ Be source at the Port of Oakland is from 50 mCi to 150 mCi.
California Radiation Control Program personnel with the assistance of U.S Customs, inspected the scrap metal and found 9 Am-241 sources. They have taken custody of the sources and will conduct analysis to identify and determine where the sources originated. Notified R4DO (D. Powers) and NMSS EO (S. Moore) and emailed TAS (R. Warren) }}[[Event description::Description::{{#Regex_clear:State of California provided the following information via email: [The] US Customs Service, Port of Oakland contacted RHB-Berkeley on the morning of 07-07-2005, reporting that a load of scrap metal bound for China had set off a radiation alarm.
