Keeping the user either involved in the development or-at the very least-using the earliest prototypes and alpha releases to get their feedback will hopefully keep the project on the right track.

A single alpha particle generates a track of from 30,000 to 70,000 positive and negative ions per cm, which may be polarized and moved about by ambient electric fields.

In the paper a personnel neutron dosimeter based on a CR-39 plastic track detector registering heavy recoils and alpha particles is described.
