On the 4850 Level, the Black Hills State University Underground Campus (BHUC) houses Sanford Lab's low-background counting facility—a class-1,000 cleanroom containing several ultra-sensitive low background counters (LBCs) used to assay materials for ultra-sensitive experiments—and an adjoining workspace can be used for a variety of disciplines.
The facility consists of a 7-foot-diameter by 21-foot-long chamber containing a full gaseous helium thermal shroud. The chamber is surrounded by a Class 100 Clean Room with an adjoining Class 1000 build-up area. The 7V chamber can be conditioned from atmospheric pressure to 10 −7 torr. [1]
ISO 14698-1 was first written in 2003. ISO 14698-1 describes the principles and basic methodology for a formal system to assess and control biocontamination, where cleanroom technology is applied, in order that biocontamination in zones at risk can be monitored in a reproducible way and appropriate control measures can be selected.
