I read with interest the paper titled "Particle Size and Mass Distributions of Selected Smokes: Effect on Ionization Detector Response" by Roger Welker and John Wagner (Journal of Fire and Flammability, Volume 8, January 1977). This work closely parallels similar studies currently being conducted by myself and others at the Center for Fire Research. After reading the paper, I feel that I must take issue with the statement that the overall decreasing sensitivity of ionization detectors to plastic smokes is caused by the increasing mean particle diameter.
