What percentage of x-ray is non-screen film sensitive to?

Non-screen film is designed to be sensitive primarily to the x-ray exposure it receives, as it directly captures the image from the x-rays themselves, rather than relying on light from fluorescent screens, which is how screen film operates. This type of film has a high sensitivity to x-rays, accounting for a significant percentage of the exposure it responds to.

The correct understanding of non-screen film sensitivity indicates that it responds to approximately 90-99% of the x-ray exposure. This allows for greater image capture and detail, highlighting its capability in applications where direct x-ray interaction is crucial, such as in high-resolution imaging.

In contrast, other options reflect varying sensitivities that are not representative of non-screen film. For instance, stating that non-screen film is only sensitive to a much lower percentage of x-ray exposure does not align with its established performance characteristics.
