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 meth
