Description/Abstract:
Radioactive contaminants dispersed through the ORNL stack system are controlled by the Operations Division and are monitored by the Operations and the Health Physics Divisions. Although the regulatory and the monitoring functions may require that essentially different types of samples be collected for the different purposes, one requirement common to both responsiblities is that the samples must accurately reflect the concentrations of radioactive materials in the effluent gases. There is reason to believe that this basic criterion is not being met by the present 3018 stack sampling system. A discussion of some of the more obvious sources of deviation from representative sampling consitutes the substance of this review, such as sampling errors due to difficulty in collecting representative samples of particles and vapors suspended in a moving gas stream and subsequent depsotion in sample delivery lines.
