Abstract

A system for measuring the size distribution of particles on which radioactive atoms are attached including: an air flow channel for receiving an influx of the radioactive atoms, a fan for controlling the air flow rate in the channel, one or more wire mesh screens in the channel, and alpha particle detectors located in the channel so as to detect the radioactive atoms. The outputs of the detectors may be connected to a computer for analysis of the outputs.
