Concern for the environment and public health, and compliance with DOE and EPA regulations require that representative sampling be conducted on exhaust stacks that emit radioactive materials. In order to design and install particulate samplers, EPA Regulation 40CFR61, Subpart H (NESHAP) specifies that particle concentration profiles be determined, in addition to velocity profiles, at the sampling cross section of all stacks requiring sampling. Neither the NESHAP regulation nor ANSI standard N13.1-1969, A3.2, p27, which is incorporated into NESHAP by reference, specify detection or analytical methods for determining effluent concentration uniformity in stacks that may emit radioactive gases or particles. Methods are described for stacks emitting nonradioactive materials, but these are not suitable for radioactive emissions, nor do the regulations specify any tolerances on the concentration uniformity for exhaust stacks. Mass tracer detection and laser light scattering detection methods are compared
