Types of Radiation
This type of radiation is commonly used in dental x-rays.
What is ionizing radiation?
This scientist discovered X-rays in 1895.
Who is Wilhelm Conrad Roentgen?
The best way to prevent cross-contamination in X-ray film handling is to use this.
What are barrier envelopes?
This device measures cumulative radiation exposure for dental staff.
What is a dosimeter?
This extraoral radiograph captures a panoramic view of the entire mouth.
What is a panoramic radiograph?
This form of radiation is non-ionizing and is used in MRI machines.
What is Radiofrequency radiation?
The first known fatality from X-ray exposure occurred to this type of professional.
Who is a radiologist/X-ray technician?
This chemical is commonly used in manual processing of X-ray films
What is a developer?
The recommended distance from the X-ray tube head for the operator during exposure is...
Answer: What is at least 6 feet (2 meters)?
What is at least 6 feet?
The X-ray beam in panoramic radiography moves in this way around the patient’s head.
What is a rotational or elliptical movement?
Alpha, beta, and gamma rays are types of this kind of radiation.
What is nuclear radiation?
This term describes a mistake made during X-ray exposure resulting in unnecessary radiation.
What is an exposure error?
In digital radiography, this eliminates the need for chemical processing.
What is digital sensor imaging?
This protective barrier is commonly worn by patients to reduce exposure.
What is a lead apron?
This component of the X-ray machine controls the size and shape of the X-ray beam.
What is the collimator?
This particle radiation is composed of helium nuclei.
What are alpha particles?
Early X-ray tubes were known by this name, based on the scientist who invented them.
What is Crookes tube?
Proper disinfection of X-ray equipment should be done with this kind of wipes.
What are EPA-registered disinfectant wipes?
This principle minimizes radiation by using the shortest exposure time possible.
What is ALARA (As Low As Reasonably Achievable)?
This part of the panoramic machine supports the patient's chin to ensure proper alignment.
What is the chin rest?
The penetration ability of gamma rays compared to alpha and beta particles is...
What is higher penetration?
The “inverse square law” relates to this aspect of radiation exposure.
What is the relationship between distance and radiation intensity?
Failure to properly fix X-ray films during processing results in this.
What is film fogging or image degradation?
Pregnant patients should be protected with special care because radiation can cause this.
What is fetal harm or developmental defects?
This device converts X-rays into visible light in digital extraoral imaging.
What is an image intensifier or flat panel detector?
