How does the inverse square law influence the choice of X-ray source-to-object distance in dental radiography?

• A. Decreasing distance from the source increases operator dose.
• B. Increasing distance from the source reduces exposure to the operator; practice uses geometry that maintains image quality while minimizing dose to the operator.
• C. Distance from the source has no effect on exposure.
• D. The inverse square law only applies to the patient dose.

Answer: (D)
