Gamma Counting Stations
Description/Name: Gamma-Ray Counting Station at the 4850-ft level
Planned use (be specific):
Primary function: Materials screening
Temporary and permanent storage: *Separated sample storage rooms for screening and for keeping
Sample and detector handling: Clean room with class 10,000, liquid nitrogen, sample preparation including assay materials
Jigs, fixtures, scaffolds, etc. necessary: Jigs for sample preparation; lifting system for open and close the counting stations. Lab fixtures: light-duty; power, lights, laboratory casework, communications (phone/computer), standard wall coverings, uninterruptible power, 15 kW of power (UPS), air monitoring for certain gases
E & O activities: daily (emergency 24/7); Utilities: air, water, heat/cooling, light, communications, commercial drains, chemical drain/disposal path, liquid nitrogen, humidity control; Radon free air; Temperature; humidity control.
