Final answer:
Flu-like symptoms are not a direct outcome of repeated unprotected radiology exposure. Symptoms listed due to radiation include nausea and vomiting, but not general flu-like symptoms. The long-term effects of radiation exposure include decreased fertility, birth defects, shortened life span, and increased cancer risk. So, the correct answer is option c.
Step-by-step explanation:
Repeated unprotected radiology exposure has been shown to produce a range of effects due to its harmful impact on cells, particularly those that reproduce rapidly. However, the listings provided do not mention flu-like symptoms as a direct consequence of radiation exposure.
Therefore, the correct answer to 'Repeated unprotected radiology exposure has been shown to produce all of the following except' is C. Flu-like symptoms. While radiation can cause nausea and vomiting, these are symptoms of radiation sickness rather than general flu-like symptoms, which include things like coughing and congestion. Moreover, the long-term effects such as decreased fertility, birth defects, shortened life span, and an increased risk of cancer have a well-documented association with radiation exposure.
