Abstract

Scintillation of scattered radiation caused by particulate matter is studied. By use of stochastic theory, expressions for mathematical expectation, variance, and scintillation index are derived. A method of measuring particulate-mass concentration with the scintillation index is proposed. The major advantage of this method is its insensitivity to lens contamination and particle-color change.
