PrepTest 33, Section 3, Question 5
The radiation absorbed by someone during an ordinary commercial airline flight is no more dangerous than that received during an ordinary dental X-ray. Since a dental X-ray does negligible harm to a person, we can conclude that the radiation absorbed by members of commercial airline flight crews will also do them negligible harm.

A flaw in the argument is its failure to consider that
there may be many forms of dangerous radiation other than X-rays and the kinds of radiation absorbed by members of commercial airline flight crews
receiving a dental X-ray may mitigate other health risks, whereas flying does not
exposure to X-rays of higher intensity than dental X-rays may be harmful
the longer and the more often one is exposed to radiation, the more radiation one absorbs and the more seriously one is harmed
flying at high altitude involves risks in addition to exposure to minor radiation
