Notes

Dilution Ventilation

Dilution ventilation is the once-

through flow technique of exchanging

outside air for inside air for comfort

and the reduction of airborne sources.

Storage

Tritium can be stored in storage beds.

Metal tritide and uranium hydride are

the most common for these storage

systems. Tritium is generally released

by heating the metal tritide.

Administrative Controls

There are many administrative controls to reduce

doses. The following are just a few that should apply

to all sites:

limitation of access time

procedures/RWPs

For tritium and tritium compounds, 10 CFR 835

Appendix D requires posting contamination areas

based on removable contamination values of 10,000

dpm/100cm2.
