Which of the following exposure factors will produce the greatest receptor exposure?
earnstyle [38]

400 mA, 70 ms is the following exposure factors will produce the greatest receptor exposure.

C: 400 mA, 70 ms

<u>Explanation:</u>

As SID builds, the introduction rate diminishes and receptor presentation diminishes. SID and the mAs required to keep up the introduction to the IR have a straightforwardly corresponding relationship (as the SID builds, the mAs required to keep up presentation to the IR increments by a corresponding sum).

An expanded SID likewise decreases amplification (size twisting). The most extreme SID ought to be utilized when conceivable to limit amplification. Infrequently, however, the SID can be purposefully diminished for amplification. SID influences size yet not shape twisting.
