What mA station would be used for an exposure with 0.6 seconds and 50 mAs?

To determine the correct mA (milliamperes) station needed for a given exposure time and mAs (milliamperes-seconds), you can use the formula:

mAs = mA × time (in seconds).

In this scenario, the mAs is 50 and the exposure time is 0.6 seconds. We can rearrange the formula to solve for mA:

mA = mAs / time.

Inserting the values from the question, we have:

mA = 50 mAs / 0.6 seconds = 83.33 mA.

Since mA values are typically rounded to the nearest whole number for practical use in radiology settings, 83.33 mA would round to approximately 83 mA. Therefore, the mA station that corresponds to an exposure of 0.6 seconds at 50 mAs is 83 mA. This aligns perfectly with the second choice provided, making it the correct answer.
