I'm an ex-Navy nuke (submarine officer), and this is very likely. A colleague of mine worked on a carrier. Because he was in the (nuclear) engineering department, he had to wear dosimetry no matter where he stood watch. One month he stood watch in the engineroom in close proximity to the reactors (and shielding). The next month he stood watch on/around the bridge, far away from the reactor but in the sun. His exposure from just being outside was noticeably higher than when he stood watch next to the reactor.
