X-ray Certification Practice

X-ray Certification Practice A dental assistant may expose radiogrpahs if - It is permissible in the state in which he or she is employed The most sensitive cells to ionizing radiation are - Reproductive cells The best type of x-ray to penetrate body tissue is - Hard rays, short wavelength Before seating the dental patient it is necessary to cover which of the following items with disposable plastic wrap - X-ray exposure control panel An exposed x-ray film covered with a plastic barrier envelope is considered to be - Contaminated Milliamperage controls - Heating of the cathode The dental assistant must utilize which of the following personal protective equipment (PPE) when exposing films? - Gloves The lead diaphragm determines the size and shape of the - X-ray beam The portion of the target that is struck by electrons is called the - Focal spot Proper collimation for the film size and target-film distance will - Decrease the radiation received by the patient To increase the penetrating quality on an x-ray beam, the auxiliary must - Increase kVp The x-ray at the center of the primary beam is called the - Central ray A test for quality control relative to manual processing may be accomplished utilizing a - Stepwedge Filtration of the X-ray beam protects the patient by - Eliminating weak wavelength X-rays from the X-ray beam Information and instructions for proper disposal of the X-ray processing solutions may be found in the - Product material safety data sheet The quality or penetrating power of secondary radiation is - Less than that of primary radiation X-ray processing tanks are considered secondary containers and according to OSHA standards must be - Labeled The time period between the effects of cumulative radiation and visible tissue is the - Latent period The amount of radiation a person receives - Is cumulative in the entire body Maximum protection of the patient requires that the X-ray beam passes through a - Lead apron A technique used to measure the operators exposure to radiation is - For the operator to wear a radiation film badge Accumulated radiation dosage for those who work with radiation may not exceed - 0-1 rem/week To avoid exposure to secondary radiation, the operator should stand - At least 6' from the X- ray head The most effective way to reduce gonadal exposure from X-rays is to - Use a lead apron
