Knight, J. Lawrence Livermore National Laboratory, Area 300 27 August 2001 ' Page 3 RESULTS The site visit occurred on Thursday, 16 August 2001. Four areas were visited, 851, 801, 816 and 883. Area 883 was the hazardous waste storage facility and was divided into two parts, north and south. These two parts, north and south, where the 90 day and one year storage areas respectively for hazardous wastes. Area 851 was an above ground explosives testing area. Area 801 was the confined explosive testing area. The main source of chemical wastes in areas 851 and 801 were the X-ray/photo development rooms. Area a 816 was the _ explosives and explosive waste storage facility. The MiniRae®during this inspection did not detect volatile organic compounds in any area. The Ludlum 3 did not pick up any radiation source that had not been previously identified by the Ludlum 19. 'The Ludlum 19 detected a 7-10 pR background of gamma rays. No radiation sources were found during the inspection with the single exception of a radioactive waste drum stored in building 883 north. This source was a 55 gallon drum which emitted 2 mR/hr immediately adjacent to the drum. Three SAIL radiation dosimeters were used. One was kept in the car and one was given to each of the two DTSC employees conducting the inspection. The following results were found: 16 August LLNL Area 300 SAIC Readings Dosimeter Total Dose Dose minus and person Start time End Time Hours MR Background D12580 0730 1450 7.33 0.09 -0.02 Jo Ann D12585 0730 1450 7.33 0.12 0.01 Alan D12588 0730 1450 7.33 0.11 NA Background SPECIFIC COMMENTS During this inspection, no unknown radiation sources were detected. While radiation sources are present, they are identified and containerized by LLNL staff. During the inspection, DTSC employees were not exposed to volatile organic compounds nor were DTSC employees exposed to a significant source of gamma radiation. Dosimeter reading indicates no exposure above background. Difference in readings on the SAIC were within the SAIC accuracy range (± 20%).
