Improvements and additions to the Multiple Path Particle Dosimetry model

A little over a decade ago, the first UC Irvine dosimetry conference was held entitled “Frontiers in Aerosol Dosimetry Research”. At that time, mechanistic dosimetry models, such as the multiple path particle dosimetry (MPPD) model, primarily focused on humans, with a model for the Long Evans rat also being available. In the intervening years, advances have occurred on a number of fronts that have led to improvements and additions to the user-friendly MPPD software program that is available free to the public. Here, we review a number of the expanded capabilities of the MPPD model. These include:
