Question
CHAPTER 1 Introduction to Radiation Protection 13 7. Why should the ALARA philosophy be 4. The term optimization for radiation established and maintained as a main part of every health care facility's radiation safety program? protection (ORP) is synonymous with the 8. When are patients more likely to overcome A. As low as reasonably achievable any radiation phobia and be willing to assume a small risk of possible biologic damage? (ALARA). B. Background equivalent radiation time BERT) C. Equivalent dose (EqD) D. Diagnostic efficacy (DE) 9. On what premise is BERT based? 10. In the medical industry with reference to 5. Standardized dose reporting for radiologic the radiation sciences, how is risk defined? REVIEW QUESTIONS 1. A patient may elect to assume the relatively procedures can lead to A. An invasion of patient privacy B. An increase in patient radiation dose. C. A reduction in patient radiation dose. D. Elimination of the need for imaging small risk of exposure to ionizing radiation to obtain essential diagnostic medical equipment radiation safety features. 6. Which of the following is a two-phase program to create radiation awareness and community education? A. ALARA B. BERT C. DE D. TRACE formation when: 2. Injury occurs 3. A specific imaging procedure for health screening purposes is prudent A. 1 and 2 only B. 1 and 3 only C. 2 and 3 only D. 1, 2, and 3 Effective measures employed by radiation workers to safeguard patients, personnel, and the general public from unnecessary exposure to ionizing radiation define: A. Diagnostic efficacy. B. Optimization. C. Radiation protection. D. The concept of equivalent dose (EqD). 7. The degree to which the diagnostic study accurately reveals the presence or absence of disease in the patient defines which of the following terms? A. Radiation protection B. Radiographic pathology C. Effective diagnosis D. Diagnostic efficacy 8. The millisievert (mSv) is equal to: A. Xo of a sievert. B. Yoo of a sievert. C. Kooo of a sievert. D. yo,o of a sievert. 3. Which of the following is a method that can be used to answer patients' questions about the amount of radiation received from a radiographic procedure? A. ALARA concept B. BERT C. BRET D. EPA 9. An effective radiation safety program requires a firm commitment to radiation safety by: 1. Facilities providing imaging services 2. Radiation workers 3. Patients A. 1 and 2 only B. 1 and 3 only C. 2 and 3 only D. 1, 2, and 3Explanation / Answer
D. 1, 2, and 3: the condition is applicable in all three cases i.e. illness, injury and imaging procedure for health screening purposes is prudent. C. Radiation protection: It is employed to protect people against the ionizing radiations. B. BERT: Background equivalent to radiation time, compares the radiation received by patient to natural background radiation. A. As low as reasonably achievable: ALARA and ORP are synonymous to each other. C. a reduction in patient radiation dose: Standardized dose reporting leads to decrease in radiation dose. D. TRACE: It is involved in awareness about radiation, understanding about safety and other education program for community and patient. D. Diagnostic efficacy: It is the degree to which the diagnosis detects the presence or absence of any disease. C. 1/1000 of a Sievert: Milli stands for 1/1000 th part. A. 1 and 2 only: Radiation safety can be achieved by facilities and radiation workers. B. Such institution is not under compliance with ALARA standards and have to take measures to bring the ESE values and doses as per the standards.
