Introducing "Controlled Areas"
Today around the lab, you might notice some new signs posting areas as "Controlled Area." Some of the locations initially posted are the Accelerator Area entrances at Gate 17, Gate 30, and the Alpine Gate.

Detailed information on Controlled Areas can be found in ES&H Manual Chapter 9, "Radiological Safety," in the requirements section under Area and Worker Classification (read it online here).
A summary of the entry requirements can be found below. Note that entry requirements for Controlled Areas are the same as for Accelerator Areas.

RCAs requirements (unchanged from previous years) are:
