In a nuclear facility, it is essential to assess and predict the radiological consequences to public during routine operations. Atmospheric dispersion models are used for the study of dispersion of radioactive releases to the atmosphere, which requires validation for operational use. The ambient concentrations of a pollutant can be measured at different distances from source in the downwind sectors, which requires a large number of air samplers to be deployed. To achieve this, a portable, programmable air sampler was designed and developed for simultaneous and automatic sampling. The system description and function are discussed in this paper.
