Question

which of these is a disadvantage of ct scan technology?
a. high cost
b. increased number of surgeries
c. inaccuracy
d. radiation exposure

Explanation:

CT scans use X - rays, which involve radiation. High cost (A) is a financial aspect, not a direct disadvantage of the technology itself. CT scans are relatively accurate (so C is wrong), and they don't directly increase the number of surgeries (B is wrong). Radiation exposure is a well - known disadvantage of CT scan technology.

Answer:

D. Radiation exposure
