3. Introduction Malaysian population ~ 23 millions
Economic activities are industrial base
Nuclear & Radiation used mainly in industry, medicine research and education
No nuclear power, but there is 1 research reactor used for research and isotope production
Industry – nuclear gauges, radiographic devices, industrial irradiators
Medicine – nuclear medicine, radiotherapy and diagnostic equipment
Research & education – less amount, low activity and short-lived radioactive materials
4. Legislative and Regulatory Infrastructure Two-tier system
Atomic Energy Licensing Act 1984
Regulations
Codes of Practice & Technical Guidance
AELA
Formation of AELB under MOSTI
Define functions of AELB
Empowerment of AELB
Form a secretariat
Fund provided by MOSTI
5. List of current regulations and supporting documents
6. Revision Process
7. Revision of documents in 2003-2004
8. Organizational structure of AELB
9. Activities of AELB On the way to full implementation of the Act to both private and public sectors
Full application of notification and authorization
Establishment of complete source inventories by AELB and MOH
Establishment of a master inventory of sources by AELB
Establishment of inspection priorities, frequencies, and schedules
Development of inspection procedures and checklists
Take enforcement actions on licensees based on finding of inspections
10. List of radiation sources- AELB
11. List of radiation sources - MOH
12. Control of occupational exposure Radiation workers are individually required to wear a personal dosimeter while in control areas.
The dosimeters are currently provided 100% by MINT’s SSDL
The service covers environmental, protection and high level of x-rays, gamma rays, beta and neutron
MINT’s SSDL
ISO 9002 version 1994 in Jan 2002
ISO 9001 version 2000 in May 2003
QC/QA
Participate in inter-comparison on Measurements of the Quality Personal Dose Equivalents HP (10) in mixed n - ? fields organized by IAEA in June 2003
13. Control of occupational exposure (2) Results good for gamma very good but out for neutron
Participate in inter-comparison at regional level (Phase 3 Round 2) for deep dose and skin dose using TLD and the results are -6 and 3%
Total dosimeters provided (2003)
films – 10,500
TLD – 800
TLD 6&7 – 200
Dosimtery for internal exposure down because of maintenance, spare parts and calibration nuclides problems
14. Control of occupational exposure (2) Use of AELB individual dose records
Results of personnel monitoring (2003)
< 0.2 mSv ~ 84 %
> 20 mSv ~ 0.6%
> 50 mSv ~ 0.1 %
MINT also provides calibration services
Covers x rays, gamma, beta and neutron
The number increases every year – 1986 (2003)
In the process to get ISO/IEC 17025 (Jun 2004)
Participate in IAEA inter-comparison for gamma calibration facilities. Results within ± 5 %
15. Instruments calibrated by MINT
16. Control of medical exposure New regulations are being drafted
Control is supported by
Codes of practice
Ministry circulars to GP (1999), private hospitals (2000)
Establishment of QA/QC systems for evaluation, review and monitoring of medical facilities, equipment and procedures
Qc tests on radiation equipment must be performed annually by certified medical physics expert.
Requirement for RPO
Requirements for medical physicists for higher risk facilities
All operations are done by trained personnel
17. Control of public exposure Sources
Radioactive discharges
Transport of radioactive materials
Waste disposal
Decommissioning of NORM contaminated plant
Most practices are involved with low activity and short half-lived radioisotopes
Establishment of a discharge limit for a licensed practice
Monitoring of discharges
Monitoring capability available at a number of facilities. Facilities in MINT participated in inter-comparison quite some times ago.
18. Control of public exposure (2) No radon problem but there is on-going project to assess the risk and population exposure.
Prepared a national policy on radioactive wastes based on IAEA SS No. 111-F
Preparing standard procedures for waste characterization and segregation
Wastes are grouped into two:
Man-made wastes – small volume, varied half-lives and activities. Generated by industries, hospitals, research and education centers
NORM wastes – big volume and low activities. Produced by mineral sands and oil industries
19. Control of public exposure (3) Waste storage in MINT for man-made wastes
ISO 9001 Version 2000
Classification of wastes is done according to IAEA SS 111-G-1.1
Inventory of rad wastes is beng established using Rad Waste Management Registry software
TC project on conceptual planning for national waste repository (3 years)
Established repository for NORM wastes
20. Control of public exposure (4) Transport – new draft regulations
Radiological emergency
Training
Domestic training conducted by MINT
External – RCA and Model Projects
Peer Review Mission
