Fermi - 2 - gamma monitor followed by beta/alpha monitor. RCA exit boundary is after the beta/alpha monitor (some of our PCMs are combined alpha/beta/gamma), RCA exit after all monitoring has been completed. Concept is highest to lowest, before exit.

Which configuration describes your plant 1 - beta/alpha monitor followed by gamma monitor. RCA exit boundary is after the gamma monitor 2 - gamma monitor followed by beta/alpha monitor. RCA exit boundary is after the beta/alpha monitor 3 - beta/alpha monitor, RCA exit boundary, then gamma monitor 4 - gamma monitor, RCA exit boundary, then beta/alpha monitor 5 - Other configuration. Explain. Thank you in advance for your reply. Sun G.
