Which term defines the highest level of laser exposure considered safe for a given duration?

Explanation:
The highest laser exposure treated as safe for a defined duration is called the maximum permissible exposure. This limit comes from safety standards and is specific to the wavelength and exposure time, reflecting how tissue responds to light. Keeping actual exposure at or below this level helps prevent eye or skin damage for the given exposure duration, with different MPE values for different wavelengths and body tissues. The other terms aren’t standard ways to express this safety boundary, and they don’t carry the same precise meaning in laser safety guidelines.
