Introduction to RF Radiation Safety / 10 / 10.19

10.19 REVISION QUESTIONS

  1. Why is an RF safety program necessary even when an installation currently complies with the applicable RF exposure limits?
  2. Explain the difference between an organization's RF safety program and an RF Radiation Safety Plan. Why might the organization require more than one Plan?
  3. Describe the responsibilities of senior management, the Responsible Person, supervisors, source operators, and workers in maintaining effective RF safety arrangements.
  4. What source, access, task, and change information is needed before RF hazards can be identified reliably?
  5. Explain the difference between an RF exposure assessment and an RF risk assessment. How do the two support one another?
  6. Why must an RF risk assessment consider indirect effects, secondary RF hazards, and non-RF hazards as well as direct human exposure?
  7. Describe the hierarchy of controls used for RF hazards and explain why higher-order controls are generally more reliable.
  8. Give three examples of engineering controls and three examples of administrative controls that may be used to manage RF exposure.
  9. What is an RF Controlled Area, and how does it differ from a site-defined exclusion zone?
  10. Why should signs and personal RF monitors support, rather than replace, effective source control and restriction of access?
  11. What information and verification are needed before work begins on or near an RF source?
  12. What is the purpose of isolation and lockout/tagout, and what should be confirmed before a source is returned to service?
  13. Why must RF training, competence, authorization, and supervision be matched to a person's exposure category and work?
  14. What exposure condition applies to a pregnant occupationally exposed worker after the employer has been notified of the pregnancy?
  15. Why do susceptible medical devices and metallic implants require individual consideration separate from ordinary compliance with the human-exposure limits?
  16. What coordination is required when contractors or several source operators share a site?
  17. What information must an exposure-assessment record preserve so that another competent assessor can understand and meaningfully compare the result?
  18. Outline the immediate, medical, technical, investigation, corrective-action, and reporting steps following a suspected RF overexposure.
  19. Why does protection of the general public rely primarily on design and effective restriction of access rather than on training or warning signs?
  20. How do management of change, auditing, worker consultation, performance indicators, and management review keep the RF safety program and its Plans effective?
