331 March 25, 1998; updated January 23, 2001 PNNL A. L. Nicholson |
PAST OPERATIONS
Beryllium brought in facility: YES
Form of beryllium: SOLID (dust)
Period of beryllium operations (dates): Start: 1974 End: 1979
Location(s) in facility that contained beryllium materials: Small
animal exposure facility.
Description of beryllium activities: The 331 Life Science Building was constructed in 1970 for biological and botanical research which were believed to include beryllium research. The building was primarily used for animal studies.
Building monitoring data summary: Four swipe samples and two air samples were collected from the small animal facility in 1974. The swipe samples ranged between 0.007 and 0.017 mg/in2 and the air samples were below the detection limits (<0.018 mg/m3). Two filter samples were submitted in 1979 with reported results of 0.04 and 0.88 ng/m3 (high volume samples). The location of these two air samples was not identified in the report.
Personnel monitoring data summary:
None identified.
Specify Engineering/Administrative controls used during
operations: None identified.
Maximum Estimated Past Be exposure: LOW
CURRENT OPERATIONS
Building still present: YES
Beryllium present: NO
Current building occupancy/activity: This building is currently used for research and experimental studies to understand molecular and cellular processes resulting from insult by physical and chemical agents.
2000 Characterization: Statistical beryllium wipe sampling was conducted in this facility on April 14, 2000 to characterize residual beryllium levels from past operations. Samples were taken in Rooms 122, 170W, 170E, and in the second floor mechanical room near penetrations made to suspect rooms. All 29 samples taken had less than the public release limit of removable beryllium (<0.2 mg/100cm2).
Maximum Estimated Current Be exposure: NONE
Basis for above information: Stone and Webster report, report, publication WHC-MR-0388, and personnel interviews.
Comments, including any additional information needed (specify): None
