It is assumed but not stated that this radiation affects all of the skinjobs as the station was chosen as a refuge by Commander Adama before he learned of the existence of biomechanical models. The radiation had deleterious effects on the Two they found at Ragnar Anchorage but not on Adama. This suggests that humans are not vulnerable to this type of radiation. However, it took some hours for the radiation exposure to have any significant impact on the Cylons, the Two observing that he was still able to walk and fight even after being on the station for several hours (although Adama expressed doubt about whether he could download in that state), and a Five on Galactica only manifested symptoms a short while after the fleet abandoned him on the station. Plutonium was allegedly used for Baltar's Cylon Detector because its radiation affects humans and Cylons differently. The detector was dropped as a method of exposing hidden Cylons early in Season 2 as the revelation that Boomer (a test subject) was a Cylon convinced the command staff that the detector did not work. In other media Cylons have made appearances in other media besides tv series and movies, including novels, comic books, and a video game. Novels In the novelization of the series pilot, the Cylons are described as a militaristic, reptilian race which has been conquering its way across the galaxy. The novelization is written by Glen Larson, the series creator, who originally intended the Cylons to be an alien species; and, in fact, dialog which was later edited out of "Saga of a Star World" illustrated this point. However, network censors were concerned about violence, so the Cylons became robots. By this time, two novels had been written describing the Cylons as multibrained aliens, so the Cylon Drone was invented to justify all the robots dying on-screen. As living, organic beings, the original Cylon troops could be promoted through the surgical implantation of a second brain. When a Cylon was elevated to Imperious Leader, he received a third brain. The novelization of the original series states that an elite class of Command Centurions act as executive officers to the Imperious Leader and are not subordinate to the IL-Series. In the TV series they are distinguished from other Command Centurions by black bands on their gold armor and are very rarely seen. Vulpa was originally of this class
