**Core Concept**
Radiographic images, also known as X-rays, are sensitive to light and require precise storage conditions to maintain their diagnostic quality. The film can be damaged by exposure to light, leading to a decrease in image quality and potentially altering the diagnostic outcome.

**Why the Correct Answer is Right**
When a radiographic film is exposed to light, the silver halide crystals that make up the film undergo a chemical change, resulting in a loss of contrast and detail. If the film is stored properly in a light-tight container or envelope, the silver halide crystals remain stable, preserving the image quality. This is especially critical for medical images, where accurate diagnosis relies on the precise detail of the radiograph.

**Why Each Wrong Option is Incorrect**
* **Option A:** Incorrect because light exposure can still occur even if the film is not directly exposed to light. Indirect light, such as from a nearby source or reflections, can still damage the film.
* **Option B:** Incorrect because storage in a light-tight container does not guarantee complete protection from light exposure. The container may not be airtight or may allow light to seep in through the seams or edges.
* **Option C:** Incorrect because the type of film used does not affect its sensitivity to light. All radiographic films require proper storage to maintain image quality.

**Clinical Pearl / High-Yield Fact**
To maintain image quality, radiographic films should be stored in a light-tight container or envelope and kept away from direct sunlight and other light sources. This is especially critical for medical images, where accurate diagnosis relies on the precise detail of the radiograph.

**Correct Answer:** C.
