Yes, I believe them. They never lied to me one single time in the Naval Nuclear Power Program. I worked on the plants. I know how the plants work. Kind of hard to tell me lies about things I'm going to work on and maintain. The amount of radiation leaking out is insignificant, and everything I've ever read states that the radiation actually measured is the same as background radiation, however, I'm skeptical of how they measure radiation at such depths. When we checked for contamination, we used handheld detectors to check every surface, which isn't possible at those depths, so I imagine the best they can do is measure radioactivity of the vicinity, which would make sense that they wouldn't find the minute traces of radioactive particles leaking and then dispersing.
You keep using that word. I do not think it means what you think it means.
