Tritium monitoring instrumentation at Rocky Flats

Monitoring for tritium at Rocky Flats is conducted to evaluate health hazards in the work area and assess environmental conditions. A wide variety of monitoring methods are employed including HTO bubblers, ionization chamber gas analyzers, surface smears, silica gel traps, and special direct gas counting. The instrumentation and methods used include both selective and nonselective techniques to evaluate tritium levels in room air, gas effluents, surface contamination, and liquid discharge. Liquid scintillation counting is used for most quantitative measurements
