If the distance from the source to the image (SID) is reduced by half, how is the x-ray intensity at the image receptor affected?

In the x-ray circuit, the transformer that helps control the number of electrons being boiled off the cathode is:

A heat unit for an x-ray tube is calculated:

An quality image is produced using a technique of 10 mAs, 100 kVp, at 180 centimeters. What would the radiographer need to do if the distance were changed to 100 cm to produce a similar acceptable image?  

If a photon interacts with matter and scatters, the photon

Which interaction with matter is responsible for the radiopaque areas seen on an image?

In the x-ray circuit, the transformer that helps control the number of electrons being boiled off the cathode is:

As scatter photon energy decreases, frequency:

As kVp increases:

An quality image is produced using a technique of 10 mAs, 100 kVp, at 180 centimeters. What would the radiographer need to do if the distance were changed to 100 cm to produce a similar acceptable image?
