Emergency Planning and Preparedness
• Assessment of the hazards• Acquisition of emergency equipment• Development of written procedures• Training
![Page 5: IAEA International Atomic Energy Agency Industrial Radiography Emergency Preparedness Day 5 – Lecture 8.](https://reader034.fdocuments.us/reader034/viewer/2022050916/5a4d1b627f8b9ab0599adeb0/html5/thumbnails/5.jpg)

Likely events : Gamma
• Radiographer failure to retract source (failure to monitor)
• Source stuck out• Source disconnection• Exposure device stuck in “exposed”
condition• Theft of exposure device• Malfunction or defeat of control system• Contamination due to damaged source

IAEA 6
Likely events : X-Ray
• Failure of automatic timer• Device energised accidentally• Radiographer failure to terminate
exposure (failure to monitor)• Damaged, faulty or defeated safety
systems• Physical damage affecting shielding

Emergency Equipment
• Radiation monitor• PPE (overalls, footwear)• Personal alarm and dosemeter• shielding material (bags of lead
shot)

Written Procedures (Emergency plan)
• Available to relevant persons• Concise instructions• Specify immediate action• Identify responsible persons
![Page 11: IAEA International Atomic Energy Agency Industrial Radiography Emergency Preparedness Day 5 – Lecture 8.](https://reader034.fdocuments.us/reader034/viewer/2022050916/5a4d1b627f8b9ab0599adeb0/html5/thumbnails/11.jpg)
IAEA 11
Example Emergency Plan :
Unshielded gamma source
1. Action by radiographer• Recognise abnormal situation• Move away from exposed source• Remain calm
![Page 12: IAEA International Atomic Energy Agency Industrial Radiography Emergency Preparedness Day 5 – Lecture 8.](https://reader034.fdocuments.us/reader034/viewer/2022050916/5a4d1b627f8b9ab0599adeb0/html5/thumbnails/12.jpg)
IAEA 12
Example Emergency Plan
• Measure radiation dose rates• Confirm extent of controlled area• Prevent access into area and
supervise• Inform RPO
![Page 13: IAEA International Atomic Energy Agency Industrial Radiography Emergency Preparedness Day 5 – Lecture 8.](https://reader034.fdocuments.us/reader034/viewer/2022050916/5a4d1b627f8b9ab0599adeb0/html5/thumbnails/13.jpg)
IAEA 13
Example Emergency Plan
2. Action by RPO• Plan a course of action based on
emergency procedures• Rehearse • Implement course of action
![Page 14: IAEA International Atomic Energy Agency Industrial Radiography Emergency Preparedness Day 5 – Lecture 8.](https://reader034.fdocuments.us/reader034/viewer/2022050916/5a4d1b627f8b9ab0599adeb0/html5/thumbnails/14.jpg)
IAEA 14
Action by RPO
If necessary :• Evacuate area• Seek technical assistance• Notify Regulatory Authority• Prepare in incident report• Arrange for dose assessment• Repair/replace equipment
![Page 15: IAEA International Atomic Energy Agency Industrial Radiography Emergency Preparedness Day 5 – Lecture 8.](https://reader034.fdocuments.us/reader034/viewer/2022050916/5a4d1b627f8b9ab0599adeb0/html5/thumbnails/15.jpg)

Training
• Personnel should be trained to deal with identified situations
• Drills and exercises should be conducted
• Useful feedback from exercises
