Communication, working knowledge of a quality radiographic image, and education all aid in protecting the patient against unnescessary radiation exposure by what?
a. Using lower radiation exposure factors b. reducing the risk of retake radiographs c. Collimating and filtering the primary beam d. creating a longer target- surface distance |

|
|
What is the minimum total filtration that is required by an x-ray machine that can operate in ranges above 70 kVp? |
2.5 mm aluminum equivalent |
|
|
What is the federally mandated size of the diameter of the primary beam at the end of the PID? |
2.75 Inches |
|
|
Radiation protection from secondary radiation may be increased by the use of an aluminum filter and a lead collimator
because the filter regulates the size of the tissue area that is exposed and the collimator prevents low energy radiation from reaching the tissue. |
The statement is correct the reasoning is false |
|

|
A. Slow speed Film |
|
|

|
|
Film badges, TLDS, OSL, DIS monitors are used to?
