Doubling the milliamperage will increase receptor exposure by how much if exposure time is halved?

Doubling the milliamperage (mA) will result in a significant increase in receptor exposure due to the direct relationship between mA, exposure time, and the amount of radiation produced. When the mA is doubled, the current allows for twice as many photons to be produced over the same duration.

In this scenario, if the exposure time is halved, it still leads to a considerable overall increase in receptor exposure. The halving of time means you're reducing the duration in which the exposure occurs, but since the mA doubled, the equations balancing exposure remain skewed towards a net gain in exposure.

By doubling the mA while halving the exposure time, you're effectively increasing the receptor exposure by a factor of two, or 100%. This is because the increase in radiation output (from the doubled mA) compensates for the decrease in time, maintaining a higher receptor exposure overall.

Thus, halving the exposure time while doubling the mA leads to a net increase of 100% in receptor exposure, making the correct answer accurate.
