How many mils is standard radiographic film base?

The standard radiographic film base is typically 7 mils thick. In the context of radiographic film, a "mil" is a unit of measurement equal to one-thousandth of an inch. This thickness provides sufficient support for the emulsion layers and ensures the film can withstand handling and processing without damage.

A base thickness of 7 mils has been established as a standard for many types of radiographic films due to its balance of durability and flexibility, which is essential for achieving high-quality imaging while facilitating ease of use in both manual and automated processing environments. Options that suggest a different thickness do not align with the established standards in the industry for radiographic film bases.
