What are the recommended storage conditions for finished radiographs?

• A. 68 degrees F and 30-50% humidity
• B. 70 degrees F (21°C) and 40-60% humidity
• C. 72 degrees F and 60-70% humidity
• D. 65 degrees F and 30-40% humidity

Answer: (B)

Maintaining a stable, moderate environment protects finished radiographs from physical and chemical changes that can degrade image quality over time. The recommended storage is about room temperature with moderate humidity, specifically around 70°F and 40-60% relative humidity. This range slows aging and chemical reactions in the film without promoting moisture-related damage.

If the environment is too dry, static electricity can cause dust attraction or artifacts on the film, and materials may become brittle. If it’s too humid, mold growth, emulsion swelling, or warping of paper can occur, accelerating deterioration. The chosen conditions balance these risks, preserving image integrity for longer.
