No: The amount of radiation reaching the us is far below toxic levels.

Iodine tablets only help when there is radioctive iodine in the environment, like what happened in JAPAN. In flying you are losing the atmospheres protection from cosmic rays. Iodine does not help this. Remember pilots are up there alot more than you and they are not keeling over dead with exposure or cancer So don't worry about the few flights you are taking.

No: Taking iodine after exposure to radioactive fallout containing Iodine 131 can block the uptake of the radioactive iodine by the thyroid. Exposure during a commercial flight is by cosmic rays so taking iodine tabs would offer no protection from the small amount of increased exposure.
