ENRRA
The Law no. 7 of 2010 established an independent
body known as “Egyptian Nuclear & Radiological
Regulatory Authority (ENRRA)”, having a public
juridical personality, reporting to the Prime Minister,
having an independent budget and centrally located in
Cairo.

Mission
Article (12) of the law states that: “the authority shall carry out
all regulatory and control works related to the nuclear or
radiation activities using the atomic energy for the peaceful
purposes, to ensure the security and safety of human,
property and environment from the risks of exposure to
ionizing radiation”.

Radiation Incidents and Follow-up Actions
![Page 18: Prof. Nadia HELAL Documents... · 2016. 6. 14. · CASE-STUDY Prof. Nadia HELAL Head of Radiation Safety Department, Egyptian Nuclear& Radiological Regulatory Authority Technical](https://reader034.fdocuments.in/reader034/viewer/2022051607/602f273ba777e1004036a746/html5/thumbnails/18.jpg)
Meet-Halfa Radiation Accident
• In 1998, due to bad practice and human error, Ir-192
capsule was lost near the pipe at the examination site.
• It was found one month later inside the house of farmer
living in Meet Halfa village (few kilometers from Cairo rail-
way station).
• The competent authorities were not informed of the lost
capsule and the company did not report it missing.
• Two persons died before the capsule was found.
![Page 19: Prof. Nadia HELAL Documents... · 2016. 6. 14. · CASE-STUDY Prof. Nadia HELAL Head of Radiation Safety Department, Egyptian Nuclear& Radiological Regulatory Authority Technical](https://reader034.fdocuments.in/reader034/viewer/2022051607/602f273ba777e1004036a746/html5/thumbnails/19.jpg)
The source was transported to the hot cell of EAEA
Hot Laboratory Center to identify its serial number.
Hence the owner of the source was identified. The rest of
the farmer family were under treatment for several months
and they are now living in good health in the village.
The case was on trial and the staffs are in jail.
![Page 20: Prof. Nadia HELAL Documents... · 2016. 6. 14. · CASE-STUDY Prof. Nadia HELAL Head of Radiation Safety Department, Egyptian Nuclear& Radiological Regulatory Authority Technical](https://reader034.fdocuments.in/reader034/viewer/2022051607/602f273ba777e1004036a746/html5/thumbnails/20.jpg)
Among the lessons learned from this accident:
It was found that radiation sources were
exchanged without notification of the competent
authorities.
![Page 21: Prof. Nadia HELAL Documents... · 2016. 6. 14. · CASE-STUDY Prof. Nadia HELAL Head of Radiation Safety Department, Egyptian Nuclear& Radiological Regulatory Authority Technical](https://reader034.fdocuments.in/reader034/viewer/2022051607/602f273ba777e1004036a746/html5/thumbnails/21.jpg)
The technical committee for ionizing radiation proposed a
draft of recommendations to secure and control of radiation
sources in use for industrial radiography.
The draft of recommendations was approved and it was
issued as the ministry of health order no 204 (2000) .
Recommendations were made for license, sources, storage
facilities and radiation protection expert duties.
Assistant radiographer training and license–notification at
ports and punishments.
![Page 22: Prof. Nadia HELAL Documents... · 2016. 6. 14. · CASE-STUDY Prof. Nadia HELAL Head of Radiation Safety Department, Egyptian Nuclear& Radiological Regulatory Authority Technical](https://reader034.fdocuments.in/reader034/viewer/2022051607/602f273ba777e1004036a746/html5/thumbnails/22.jpg)
In 1998
• EAEA was informed through IAEA that a Cs-137 source was found within a waste cargo in Amsterdam port.
• That waste was imported from Alexandria, Egypt. The source was unshielded and its activity was 1 mCi.
•
• EAEA reported to the ministry of health (the relevant competent authority for sealed sources).
![Page 23: Prof. Nadia HELAL Documents... · 2016. 6. 14. · CASE-STUDY Prof. Nadia HELAL Head of Radiation Safety Department, Egyptian Nuclear& Radiological Regulatory Authority Technical](https://reader034.fdocuments.in/reader034/viewer/2022051607/602f273ba777e1004036a746/html5/thumbnails/23.jpg)
Investigation leads to the company who issued un-
authorized certificate that the waste does not contain
radioactive materials
The company was terminated as well the user
license.
![Page 24: Prof. Nadia HELAL Documents... · 2016. 6. 14. · CASE-STUDY Prof. Nadia HELAL Head of Radiation Safety Department, Egyptian Nuclear& Radiological Regulatory Authority Technical](https://reader034.fdocuments.in/reader034/viewer/2022051607/602f273ba777e1004036a746/html5/thumbnails/24.jpg)
In 2002In 2002
• During 2002 two incidents were reported.
• The first incident was a container recognized by
an EAEA technician due to the presence of the
ionizing radiation sign.
• The technician had completed radiation protection
course recently.
![Page 25: Prof. Nadia HELAL Documents... · 2016. 6. 14. · CASE-STUDY Prof. Nadia HELAL Head of Radiation Safety Department, Egyptian Nuclear& Radiological Regulatory Authority Technical](https://reader034.fdocuments.in/reader034/viewer/2022051607/602f273ba777e1004036a746/html5/thumbnails/25.jpg)
The container was reported in a waste store in
Cairo ready for sale. All the relevant information was
written in English.
It was a shielded container where Am-Be neutron
source (yield =105 ns -1) was in use for moisture
measurements.
![Page 26: Prof. Nadia HELAL Documents... · 2016. 6. 14. · CASE-STUDY Prof. Nadia HELAL Head of Radiation Safety Department, Egyptian Nuclear& Radiological Regulatory Authority Technical](https://reader034.fdocuments.in/reader034/viewer/2022051607/602f273ba777e1004036a746/html5/thumbnails/26.jpg)
That source was imported to Egypt through the official
channels in 1975.
It was in use for research purposes for years.
It was recovered by EAEA and it was in the EAEA
radioactive waste storage facility.
![Page 27: Prof. Nadia HELAL Documents... · 2016. 6. 14. · CASE-STUDY Prof. Nadia HELAL Head of Radiation Safety Department, Egyptian Nuclear& Radiological Regulatory Authority Technical](https://reader034.fdocuments.in/reader034/viewer/2022051607/602f273ba777e1004036a746/html5/thumbnails/27.jpg)
• In 2002• A second incident has taken place where an Industrial gamma
camera has been stolen from factory car located in residential
area of Cairo.
• The owner of the camera and the radiation protection expert
have reported it to the competent authorities next day.
• Three thieves have stolen the camera and tried to open it, they
sold it to waste company where it kept for few days.
• The camera was returned to the house of one of the thieves,
where his wife and children were in the house.
![Page 28: Prof. Nadia HELAL Documents... · 2016. 6. 14. · CASE-STUDY Prof. Nadia HELAL Head of Radiation Safety Department, Egyptian Nuclear& Radiological Regulatory Authority Technical](https://reader034.fdocuments.in/reader034/viewer/2022051607/602f273ba777e1004036a746/html5/thumbnails/28.jpg)
Then the thief dropped it in Ismalia canal.
After proper searching the camera was found by the diver and it
was surveyed and secured in transport container and kept
under the supervision of the competent authority.
The company technical staff are still under trial.
Members of the public involved in this incident were
1-Three thieves
2-Four workers at the waste facility
3-A housewife and 2 children.

LESSONS LEARNEDLESSONS LEARNED
which govern the national law The need for
handling of radiation sources and facilities
was recognized, which lead to the issue
of Egyptian nuclear and radiation safety law
No 7, 2010
![Page 30: Prof. Nadia HELAL Documents... · 2016. 6. 14. · CASE-STUDY Prof. Nadia HELAL Head of Radiation Safety Department, Egyptian Nuclear& Radiological Regulatory Authority Technical](https://reader034.fdocuments.in/reader034/viewer/2022051607/602f273ba777e1004036a746/html5/thumbnails/30.jpg)
• ENRRA has carried out a complete and intensive review
of safety guidelines and regulatory requirements with the
aim of formulating a set of new regulations to protect
people and the environment.
• Experiences were gained for strengthening the internal
capability to emergency response and disseminating the
concept of information to avoid hazard consequences of
any radiological accident.

Strengthening and Improving the Practical Capabilities of
the N/R-EC on both National and International Levels by
Participating in IAEA International Drills
e.g. :Convex 2b& Convex 3.
The regulatory authorities should perform an investigation to
determine the causes, contributing factor, lessons learned,
recommendations in order to prevent the occurrence of
such events.
