What is the purpose of a step wedge in a QA program?
Answer: Evaluating film contrast and density consistency over time
An aluminum step wedge image is compared over time to detect changes in density and contrast.
How should lead aprons be stored to prevent damage and loss of protection?
Answer: Hung on a rack or laid flat
Folding or creasing can crack the lead lining, so aprons should hang or lie flat.
Which method is used to inspect lead aprons for cracks or holes?
Answer: Periodic radiographic or fluoroscopic examination and visual checks
Imaging the apron reveals defects not visible on the surface.
Which principle states that exposure to radiation should be kept as low as reasonably achievable?
Answer: ALARA
ALARA is the guiding philosophy for minimizing radiation dose.
Which technique factor adjustment lowers patient dose when using digital receptors compared with conventional film?
Answer: Reduced exposure settings are typically possible
Digital sensors are more sensitive, so exposure can often be reduced while ALARA and shielding still apply.
A patient asks whether dental x-rays are safe. What is the best response?
Answer: Explain the benefits, the low dose, and the safeguards used, including shielding and ALARA
Honest, informative communication supports informed consent and trust.
Which agency's regulations most directly govern dental x-ray equipment certification and use in each state?
Answer: State radiation control program
States regulate x-ray machine registration, inspection, and operator requirements.
