New physics files and changes to existing physics files in PS6 must be authenticated by a responsible user (e.g. a medical physicist). Every time a physics file is loaded a checksum is calculated and compared to the authenticated checksum recorded in PSdatabase.sqlite for that file. If the checksums do not match the file is flagged and cannot be used for dose calculations until it has been authenticated. Physics files are initially authenticated the first time PS is run after installation by unlocking physics and clicking the Authenticate button next to the source menu for a single file or the Authenticate All Files button in the lower right corner.
You can add a table of manufacturer's standard activity batches in this panel.
You can add a comment to the physics file in this panel.
Any errors detected when loading a physics file are listed in this panel.
