ARRT registry review covering radiation protection
| Question | Answer |
|---|---|
| What does the linear threshold curve show? | responses that are proportional to the radiation dose received only after some particular dose is received (Radiography Prep pg 235) |
| What is the linear non-threshold curve used to illustrate? | responses such as radiation induced leukemia, cancer, and genetic effects (Radiography Prep pg 235) |
| What are early effects of radiation? | responses that occur very soon after exposure and are usually as a result of high dose in short period of time (Radiography Prep pg 236) |
| What are late effects of radiation? | can appear years after exposure: carcinogenesis, cataractogenesis, embryologic effect, and lifespan shortening (Radiography Prep pg 236) |
| According to the Law of Bergonie' and Tribondeau, what tissue are considered radiosensitive? | Stem cells, young, immature cells, and highly mitotic cells (Radiography Prep pg 238) |
| What are some ways to reduce risk to recently fertilized ovum? | elective scheduling/ 10-day rule, patient questionnaire, and posting (Radiography Prep pg 242) |
| What are somatic effects of radiation? | affect the irradiated body itself (Radiography Prep pg 245) |
| What are the stages of Acute Radiation Syndrome? | Prodromal, latent, manifest illness, and recovery or death |
| What are the cardinal rules of radiation protection? | time, distance, and shielding (Radiologic Sciences for Technologists Tenth Edition pg 539) |
| Where does a technologist receive the majority of their occupational dose? | Fluoroscopy (Radiologic Sciences for Technologists Tenth Edition pg 544) |
| What are some types of fluoroscopic protection features? | Source-to-skin distance, primary protective barrier, filtration, collimation, exposure control, bucky slot cover, protective curtain, cumulative timer, and dose area product (Radiologic Sciences for Technologists Tenth Edition pg 550-552) |
| What is the recommended yearly occupational dose limit for radiologic personnel? | 0.5 Sv/yr (5000 mrem/yr) (Radiologic Sciences for Technologists Tenth Edition pg 582) |
| Extremity monitoring must be provided for interventional radiologists. True or false? | true (Radiologic Sciences for Technologists Tenth Edition pg 583) |
| What types of personnel radiation monitors are used in diagnostic radiology? | film badges, thermoluminescence dosimeters, and optically stimulated luminescence dosimeters (Radiologic Sciences for Technologists Tenth Edition pg 589) |
| Where should the radiation monitor be placed if the radiologic technologist participates in fluoroscopy? | on the collar above the protective apron (Radiologic Sciences for Technologists Tenth Edition pg 591) |
| What is the dose limit for technologists during pregnancy? | 0.5mSv/mo (50mrem/mo) (Radiologic Sciences for Technologists Tenth Edition pg 593) |
| What is the dose limit for the fetus for the period of pregnancy? | 5msv (500mrem) (Radiologic Sciences for Technologists Tenth Edition pg 593) |
| Technologists are required to wear two dosimeters during preganancy. True or false? | true (Radiologic Sciences for Technologists Tenth Edition pg 593) |
| What is the primary function of filtration? | to reduce patient skin dose (Radiography Examination pg 143) |
| What personnel radiation monitor will provide an immediate reading? | pocket dosimeter (Radiography Examination pg 144) |
| Radiation output from a diagnostic x-ray tube is measured in what unit of measurement? | roentgen (Radiography Examination pg 145) |
| The skin response to radiation exposure, which appears as reddening of the irradiated skin area- | erythema (Radiography Examination pg 147) |
| what is direct effect? | occurs with high-LET radiations and when ionization takes place at the DNA molecule itself (Radiography Examination pg 175) |
| what is indirect effect? | happens when ionization takes place away from the DNA molecule in cellular water (Radiography Examination pg 175) |
| What is the annual occupational whole-body dose equivalent limit for students under the age of 18? | 1mSv (100mrem or 0.1 rem) (Radiography Examination pg 150) |
