|---|---|
| BERT emphasizes that radiation is an_________part of our environment. | Innate |
| Radiation exposure should always be kept at the_________possible level for the general public | Lowest |
| Effective radiation protection consists of the tools and techniques primarily designed to_________ radiation exposure while producing______________diagnostic images. | minimize and optimal quality |
| When ionizing radiation is used to obtain a mammogram for the welfare of a patient, the directly realized___________of the exposure to this radiant energy________________any slight________of inducing a radiogenic malignancy or any genetic defect. | benefits, far outweigh, and risk |
| in medicine, when radiation safety principles are applied correctly during imaging procedures, the______________deposited in living tissue can be limited, thereby reducing the potential for________________________. | energy and biologic effects |
| Diagnostic efficacy is____________when assential images are produced under recommended radiation protection guidelines. | maximized |
| The rationale for______________comes from evidence compiled by scientists over the past century. | ALARA |
| Radiologic technologist and radiologists follow____________procedures. | established |
| to use_____________as a basic principle for radiation, a radiographer can reduce the amount of x-ray "beam on" time. | time |
| Patients not only should be made aware of what a specific procedure involves and what type of cooperation is required, but also must be informed of what needs to be done, if anything as a_________to their examination. | Follow up |
| Radiologic technologists and radiologist are educated in________operation of radiation producing imaging equipment. | safe |
| a radiographer should alaways shield the patient with appropriate _________and/or__________shielding. | gonadal and specific area |
| The____________concept should serve as a guide for the selection of technical exposure factors. | ALARA |
| _________does not imply radiation risk; it is simply a means for comparison. | BERT |
| Optimal radiographic images should be obtained with the__________exposure. | first |
| Radiologic technologists and radiologists use___________devices whenever possible. | protection |
| Management in the health care facility should perform a periodic exposure_________to determine how radiation exposure in the work place may be lowered. | audit |
| ____________understanding of biologic effects associated with diagnostic radiology was gained throughout the twentieth century. | greater |
| The millisievert (mSv) is a__________of the sievert (Sv). | subunit |
| X-rays are a form of________________radiation; therefore, their use in medicine for the detection of disease and injury requires____________measures. | ionizing and protective |
| Imaging facilities must have an effective radiation safety program that provides patient protection and patient__________. | education |
| Ionizing radiation such as x-rays have both a__________and a__________ potential. | beneficial and destructive |
| Radiographers should select the_________smallest radiation exposure the produces useful radiographic images. | smallest |
