According to the National Council on Radiation Protection, the monthly gestational dose equivalent limit for embryo/fetus of a pregnant radiographer is

Which of the following pathologic conditions will require an increase of 30% of the usual mAs in order to obtain the appropriate radiographic density?

A new linear focused grid has been installed in the table bucky of a radiographic unit.  The first test image taken shows a considerable loss of radiographic density on the left and right sides of the image.  The most likely cause of this is an

This radiographic examination shown below in Image C, of the urinary system with use of contrast media is termed a/an:  (IMAGE C)  

An abdominal radiograph is taken of a patient measuring 19 cm.  If all the same conditions are maintained and a second image is taken on a different patient measuring 29 cm, the second image will most likely have a/an:          1.  Decreased radiographic density ( decreased receptor exposure)          2.  Increased image contrast          3.  Decreased amount of secondary scatter

Effects of radiation where the probability of occurrence, not severity of occurrence, is proportional to the dose are called:
