What Does AMAD Stand For?

AMAD stands for Activity Median Aerodynamic Diameter

AMAD, or Activity Median Aerodynamic Diameter, is a critical parameter used in aerosol science to describe the size distribution of airborne particles. It represents the median diameter of particles in an aerosol population, weighted by their aerodynamic behavior, which influences their deposition in the respiratory tract. Understanding AMAD is essential for assessing the effectiveness of inhaled drug delivery systems, evaluating environmental air quality, and studying the health effects of particulate matter exposure.
