There is a sign on the entry to most most plants, "Abandon all hope all ye who enter herein." We all wear suits and ties. Many wear beards and look like pirates. You can smoke but only if you are on fire. Cell phones are allowed until you get caught. We used to wear TLD's and Electonic dosimeters, all were made obsolete when it was discovered taking two "No Dose" tablets prevented any radiation exposure.
I hope you take with a grain of salt any of your possible answers received here.
