Well, not literally so, not at the low altitudes used for manned
spacecraft. But the South Atlantic Anomaly (which is presumably what he
means by the "Brazilian Magnetic Anomaly") is a place where the lower
fringes of the inner belt hang down unusually low. Problems could
plausibly arise there, with large numbers of high-energy particles perhaps
confusing simple sensors built for milder conditions. (The SAA is
generally a bad place to operate electronics, with high noise levels in
imaging sensors, flipped bits in memories, etc.)
