It is. The rule of thumb in the medical community is that it is roughly
equivalent to a low-dose X-ray. IIRC one of the worst parts isn't the
radiation itself, it is secondary stuff from cosmic rays hitting the
body of the plane on the way in, creating a shower of e.g. beta
particles or other ionizing radiation. Radiation in general causes
oxidative damage to cells, so take your antioxidants if you plan to fly.
