I have worked at sites where we left them in racks and others that allowed us to take them home. If there was a concern outside of work (i.e in college) we were issued TLD's by the college. Background radiation levels changed globally after the use of Atomic weapons. The Gollnick, Moe, the NukeWorker study guides and most College level Nuclear Training modules provide the details of how it all works (within reason). The use of TLD's, on site and off site monitoring, when, where and how are explained. If you understand the mechanics of it, you will understand where everyone was coming from. As long as a site meets the standards set forth in the 10 CFR 20, ANS/ANSI requirements and site's licensing for NRC and DOE Standards and ANS/ANSI requirements and 10 CFR 835 for DOE and etc. It does not matter what means they use to comply, as long as they comply. This is a concept that tends to elude many spectators.
Good Luck
