In this chapter we discuss some of the major techniques for measuring aerosols, particularly radioactive aerosols. We first review some of the common techniques for measuring aerosols whether radioactive or not. It will be evident that only a subset of these approaches is suitable for radioactive-aerosol applications. Two physical processes particularly important for collection and measurement of aerosol particles are impaction and diffusion to surfaces. We provide background on these processes before going on to discuss their application to aerosol collection and measurement. We then focus specifically on radioactive aerosols. Many of our examples will involve the use of air filters to measure atmospheric activity concentrations, since this is probably the single most common approach to radioactive-aerosol measurement.
