Question

Which of the following is an acceptable approximate entrance skin exposure (ESE) for a PA chest radiograph?

A) 1 milliampere-second (mAs)
B) 10 milliampere-second (mAs)
C) 100 milliampere-second (mAs)
D) 1000 milliampere-second (mAs)

Answer 1

The acceptable approximate entrance skin exposure (ESE) for a PA chest radiograph is 10 milliampere-second (mAs).

Step-by-step explanation:

The acceptable approximate entrance skin exposure (ESE) for a PA chest radiograph is 10 milliampere-second (mAs).

Entrance skin exposure refers to the amount of radiation that the skin receives when it is exposed to an x-ray. It is typically measured in milliampere-seconds (mAs). The appropriate ESE for a PA chest radiograph is around 10 mAs.

It's important to note that the ESE can vary depending on factors such as the specific x-ray machine used and the individual patient's needs. Healthcare professionals carefully calibrate and adjust the radiation dose to ensure optimal image quality while minimizing patient exposure.
