Limited Scope of Radiography Practice Exam (2023/2024) 100% Pass

Limited Scope of Radiography Practice Exam (2023/2024) 100% Pass what statements are correct regarding the link between radiation and genetic effects The link has been demonstrated in animal studies . Increased risk to humans cannot be predicted with respect to an individual. The changes in kilovoltage (kVp) will result in the greatest reduction of patient dose, when milliampere-seconds (mAs) is adjusted to compensate for the change Increase kVp by 30% The following image receptor (IR) system speeds will result in the lowest patient dose Faster speed IR system The primary purpose of using gonad shields reduce the likelihood of genetic effects Are gonad shields Contact and shadow gonad shielding should be used when the gonads are within 5 cm of the radiation field the greatest cause of unnecessary radiation to patients that can be controlled by the limited operator is repeat exposures the limited operator can reduce repeat exposure clearly instructing patients how does the x-ray beam restriction minimize patient exposure it limits the radiation field to the area of interest what is the device that allows the limited operator to vary the size of the radiation field collimator how does filtration reduce patient exposure removes longer-wavelength photons The National Council on Radiation Protection and Measurements(NCRP) recommendation for the amount of total filtration 2.5 mm Al equiv Three principal methods used to protect limited operators from unnecessary radiation exposure time, distance, and shielding The following is not a type of personal radiation shielding Shadow personnel shielding must be worn on the rare occasion during which the limited operator may need to remain in the radiographic room during an exposure to assist the patient in maintaining the proper position. What is the source of the greatest radiation hazard under this circumstance.? scattered radiation from the patient the term for radiation the escapes from the x-ray tube housing leakage radiation why are limited operators prohibited from activities that result in direct exposure to the primary x-ray beam they are considered occupationally exposed individuals distance, as a method used to limit operator exposure, means that the operator should maximize the distance from the source during an exposure shielding worn for personnel protection is designed to attenuate what source of exposure scatter radiation the acronym for a common type of personnel dosimeter TLD What is the recommended placement for personnel dosimeter on the body of the limited operator the badge should be worn in the region of the collar on the anterior surface of the body and outside the lead apron, if worn The NCRP recommended annual effective dose limit for occupational exposure 5.0 rem (0.05 Sv) The
