An x-ray exposure at 50 inches results in a beam intensity of 200 µGy. Estimate the new intensity for a distance of 40 inches.

If the same exposure factors are used on four different radiographs and all that is changed is the SID, which radiograph would have the greatest IR exposure? The one taken at a:

If the OID is 8 inches and the SID is 72 inches, what is the magnification factor?

If the image is 6 inches wide and the object is 4.5 inches wide, what is the percent magnification?

Considering radiographs produced with the following factors, which statement is true?Radiograph ARadiograph B500 mA500 mA0.02 sec0.08 sec36-inch SID72-inch SID

All factors remaining constant, which of the following set of exposure conditions would yield an image with the GREATEST radiographic IR exposure?

Which one of these would produce the least magnification?

Elongation of a radiographic image will most likely occur from a/an:

A patient presents to the radiology department for a foot radiograph and upon assessment of the patient, the technologist sees that the patient has stepped on a nail and the nail is still sticking out of the plantar surface of the foot approximately two inches. This nail will create object-to-image distance (OID) that cannot be avoided on an anteroposterior (AP) foot radiograph. What steps should the radiographer take to prevent the size distortion that would be created by the long OID?

During a fluoroscopy procedure, the x-ray technologist stands at 5 meters from the x-ray tube for 1 hour and acquires an equivalent dose of 0.1 mSv. If the technologist had stood at a distance of 1 meter, what would their dose have been?
