P-3a-150 1 Locating Air Samplers Inside a Room Using Qualitative Airflow Studies

The concentration of airborne radioactive materials inside a room can vary widely from one location to another, sometimes by orders of magnitude, even for locations that are relatively close. Inappropriately placed air samplers can give misleading results and, therefore, the placement of continuous air monitors or samplers is a critical component in rapid and reliable detection of releases of radioactive materials
