Discuss the three general radiation protection principles that guide radiation safety plans
What will be an ideal response?
ANSWER:
The three radiation protection principles are justification, optimization, and dose limitation. Because radiation exposure comes with known risks, justification that the benefits outweigh the risks of the procedure is necessary. Optimization means achieving a dose as low as reasonably achievable (ALARA). This means the minimal dose to be effective for diagnosis or treatment should be used, in order to minimize hazardous risks. Finally, dose limitation entails monitoring healthcare workers and other exposed individuals to ensure they do not exceed legal dose limits.
