RBS TEST EXAM 3 WITH CORRECT AND VERRIFIED ANSWERS

RBS TEST EXAM 3 WITH CORRECT AND VERRIFIED ANSWERS control monitor - CORRECT ANSWER-- Serves as a basis for comparison with the remaining OSL badges after they have been returned to the monitoring company for processing - determines whether a batch of dosimeters have been exposed to radiation in transit from health facility extremity dosimeter - CORRECT ANSWER-TLD ring that may be used by an imaging professional as a second monitor while performing fluoroscopic procedures that require the hands to be near the primary x-ray beam geiger-muller survey meter - CORRECT ANSWER-serves as the primary portable radiation survey instrument for area monitoring in nuclear medicine facilities glow curve - CORRECT ANSWER-represents a unique signature of the exposure received by the TLD dosimeter ionization chamber-type survey meter (cutie pie) - CORRECT ANSWER-This instrument is both a rate meter device (for exposure rate or dose rate in air) used for area surveys and an accurate integrating or cumulative exposure or dose measurement instrument for x-radiation and gamma radiation and, if equipped with a suitable window, for recording beta radiation as well. optically stimulated luminescence (OSL) dosimeter - CORRECT ANSWER-personnel radiation monitors that use aluminum oxide crystals. These crystals, once exposed to ionizing radiation and then subjected to a laser, give off luminescence proportional to the amount of radiation received MOST COMMON DEVICE personnel digital ionization dosimeter - CORRECT ANSWER-a fairly new device that provides radiation workers with an immediate measurement of radiation exposure while including features such as long-term exposure tracking personnel dosimeter - CORRECT ANSWER-Provides an indication of the working habits and working conditions of diagnostic imaging personnel personnel dosimetry - CORRECT ANSWER-the monitoring of radiation exposure to any person occupationally exposed on a regular basis to ionizing radiation personnel monitoring reports - CORRECT ANSWER-A written report of occupational radiation exposure of personnel prepared by a monitoring company. pocket ionization chamber (pocket dosimeter) - CORRECT ANSWER-The *most sensitive* type of personnel dosimeter. *Not commonly used in diagnostic imaging*. proportional counter - CORRECT ANSWER-A radiation survey instrument generally used in a laboratory setting to detect alpha and beta radiation and small amounts of other types of low-level radioactive contamination. NO USEFUL PURPOSE IN DIAG. IMAGING radiation survey instruments - CORRECT ANSWER-Area monitoring devices that detect and measure radiation thermoluminescent dosimeter (TLD) - CORRECT ANSWER-A TLD measures ionizing radiation exposure by measuring the intensity of visible light emitted from a crystal in the detector when the crystal is heated. TLD analyzer - CORRECT ANSWER-Measures the amount of ionizing radiation to which a TLD badge has been exposed action limits - CORRECT ANSWER-Limits for occupational exposure that are set by the medical facility well below regulatory values (typically 1/10 of action limit) agreement states - CORRECT ANSWER-Individual states of the U.S. that have entered into an agreement with the NRC to assume responsibility for enforcing radiation protection regulations through health departments ALARA concept - CORRECT ANSWER-Concept of radiation protection that states that all exposures should be kept "as low as reasonably achievable" Annual occupational effective dose limit - CORRECT ANSWER-An upper boundary limit for radiation workers for a yearly whole body exposure of 50 mSv (lifetime EfD in mSv should not exceed 10 x persons age) cumulative effective dose (CumEfD) limit - CORRECT ANSWER-A radiation worker's lifetime EfD must be limited to his or her age in years times 10 mSv. This limit pertains to the whole body. effecting dose (EfD) - CORRECT ANSWER-Quantity used to provide measure of overall risk of exposure to humans from ionizing radiation and takes into account the type of radiation and tissue exposed effective dose (EfD) limiting system - CORRECT ANSWEReffective dose limit (EDL) - CORRECT ANSWERequivalent dose (EqD) - CORRECT ANSWER- International Commission on Radiological Protection (ICRP) - CORRECT ANSWERlifetime effective dose - CORRECT ANSWERNational Council on Radiation protection and measurement (NCRP) - CORRECT ANSWERnegligible individual dose (NID) - CORRECT ANSWERNuclear Regulatory Commission (NRC) - CORRECT ANSWERoptimization - CORRECT ANSWERradiation hormesis - CORRECT ANSWERradiation induced malignancy - CORRECT ANSWERradiation safety committee (RSO) - CORRECT ANSWERstochastic effects - CORRECT ANSWERtissue reactions - CORRECT ANSWERtissue weighting factor (Wt) - CORRECT ANSWERbrightness - CORRECT ANSWER-The amount of luminescence of a display monitor computed radiography (CR) - CORRECT ANSWER-Process in which an image is captured on a removable digital storage cassette using storage phosphorus technology control panel or console - CORRECT ANSWER-Where technical exposure factors, such as milliamperes (mA), peak kilovoltage (kVp), and exposure duration (mS) are selected and visually displayed cumulative timer - CORRECT ANSWER-Used with fluoro units that measures the x-ray beam "on" time and sounds an audible alarm when activated for five minutes Diagnostic-type protective tube housing - CORRECT ANSWER-Required to safeguard the patient and imaging personnel from off focus, or leakage, radiation by restricting the emissions of x-rays to the area of the useful or primary beam digital fluoroscopy (DF) - CORRECT ANSWER-Technique in which fluoroscopic image exists in digital form in the image acquisition pro
