Regular Monitoring
Although clearly-defined policies have not yet been
established for clearance from regulatory control, discharge
control and waste management, regular monitoring is
performed both at the source of discharge and in the
environment by the Department of Atomic Energy.
Codes of Practice and Guidance notes
Code of Practice for nuclear medicine has been developed by the
Ministry of Health
Code of Practice on occupational radiation protection, public protection,
medical exposure control, radioactive waste management and transport
of radioactive materials are being prepared by DAE.
Some guidance notes in local language.
Inspecting and testing machinery and equipment relating to atomic energy;
Determining nuclear material, radioactive material or irradiation apparatus, that is not suitable for further utilization or retention.
Issuing registration certificates for keeping in possession of the radioactive materials or radiation apparatus;
Issuing license for utilization, production, storage, distribution or sale of the radioactive material or radiation apparatus;
Granting prior permission for import or export of the radioactive material or radiation apparatus.
Supervising the performance of duties and functions of the inspectors
The Regulatory body has taken responsibility for:
Notification and National Register of Radiation
Sources:
the software used
RAIS (Regulatory Authority Information System) version 3.0 which is a
tool being developed by IAEA for Regulatory Authorities
collected the list of the private clinics and hospitals with the help of
Ministry of Health
register and license all radioactive sources by DAE with
authorization by Ministry of Science and Technology
Inspection
DAE officers have done inspection for private companies and government services since 1997.
Radiation detectors used
– digital kVP Meter Model 230, Digital X-Ray Exposure Timer Model 231A and Neon beam analyzer.
– ALERT Monitor 4 and Series 1000, mini-rad are used
clinics and hospitals are being inspected not only for radiation leakage but also for quality control of their X-ray machines.
Food &Environmental Monitoring Division has
taken responsibility for:
Radioactivity monitoring and certification of imported diary
products and exported agricultural products.
Low Level Alpha/ Beta counting system (CANBERRA 2401),
NaI detector are used for measuring the radioactivity in food.
Monitoring the radiation levels in rain water and air samples.
GM counter, Low Level Alpha/ Beta counting system
(CANBERRA 2401) are used for measuring the beta activity
of a sample (air filter or rain water).
Occupational Radiation Protection
DAE is extending personnel dosimeter services to the radiation workers on national level.
TLD badges are distributed to the workers to wear during their duty hours.
Checked the exposure dosage every 2 months.
Received an average dose of 0.5 mSv/2 months.
Sources of Public Radiation Exposure in Myanmar
Radioactive Effluents released into the Atmosphere and into
the Water
(From agricultural and industrial applications)
Radioactive waste from disused radioactive sources and
equipment
(From medical and industrial applications)
Control of Public Exposure
Public exposure is controlled by sufficient thickness of shielding
material and control of access.
Registry, inventory and safe storage of unused radioactive sources
and materials.
Radioactivity measurement in rainwater and air samples.
Radioactivity monitoring and certification of imported diary
products and agricultural products for export.
Safe management of radioactive waste.
DAE has taken responsibility for:
Part II.
About radioactive waste management in
Myanmar
Classification of Radioactive Wastes
Cleared material/ waste
Low level (short-lived)/ Decay waste
Low and immediate level short-lived waste (LILW-SL)
Low and immediate level long-lived waste (LILW-LL)
High level waste (HLW)
To classify waste, it depends on the types of materials
and the level of radioactivity
Low-level waste were stored in Myanmar
High-level waste were re-exported to Manufacturer
Waste Management & Transport Division has taken
responsibility for:
Waste management in medical practices
Waste management in industrial applications and research
Registry and safe storage of radioactive waste
Transport of radioactive sources
Re-exportation of sources to the country of origin
Application of radiation in Myanmar
The use of ionizing radiation and radiation sources
The various area such as radiotherapy, radio diagnosis,
nuclear medicine, medical research, agricultural services,
livestock breeding, environmental radiation monitoring,
training and research etc., ionizing radiation and
radioisotopes have been widely applied in the country.
Main Radioactive Waste Producers in Myanmar
Industries
Medicine
Agricultural Services
Industries
In Myanmar International Airways , Myanmar Heavy Industry and
Myanmar Railways Transportation , radiation sources are used as
analytical tools.
The fixed sealed sources are being used for measurement of physical
parameters such as density, volume, thickness, level, etc.
The radioactive sources are being used by Myanmar Oil Corporation
in the exploration of natural resources.
The sources in solid form require little processing before disposal as
radioactive waste.
The users deposit their sources at their own temporary storage where
these are stored in accordance with the IAEA guidelines
Medicine
The radioisotope commonly use in nuclear medicine are Am 241,Ba
133, Co-60,Cs-137,Sr-90,etc;. The Ra-226 had been used as
brachytherapy source for treatment of cancer.
As IAEA offer to know the amount of Radium, two Korean experts
and one IAEA technical officer in Oct 2000 keep them as the waste
safely and systematically.
Radium needles and tubes are used in YGH and MGH.
1429.5mg of spent radium sources were safely conditioned by Korea expert team under the supervision of IAEA technical officer and under the control of DAE authority
Encapsulated in 27 small capsules and three large capsules and conditioned in 3 lead shields, producing 3 packages.
The inventories were distributed into 3 shielding devices, holding 500, 459.5 and 470 mg.

Natural radioactivity in Myanmar
The extent of human activities that enhance the level of natural radioactivity (including NORM) is still very small.
The potential risks posed to the public and the environment by radioactive residues used in medicine and industry are thus low.
Only low-level natural radioactivity has been found from past practices.
Part III.
Legislation and Regulatory Framework
Legislation and Regulatory Framework
• Past Situation
• Atomic Energy Law enacted in 1998
• Regulation was waiting for approval
• Present Situation
• Existing Atomic Energy Law is Under Review and drafting.
• Regulation on this AEL is at the preparation stage.
• Drafting new Nuclear Safety Law
• Regulation on this NSL is at the preparation stage.
Existing Atomic Energy Law
• Enacted on 8th June 1998
• Consists of 39 Articles in 14 Chapters
• Primarily provided for ensuring safety in the utilization of
radioactive material and irradiation apparatus.
• Regulation of Radioactive Waste Management will be
included as a one of the chapters in the new Nuclear Safety
Law based on the IAEA Safety Standard Ser ies.
• In new Nuclear Safety Law, waste procedures and
emergency preparedness will be included.
Law on of Radioactive Waste(and Spent fuel)
Management
CONCLUSION
At present, we do not have nuclear power plant, research reactors or fuel
cycle facilities and as such we do not have problems related to high level
waste but appropriate measures are to be taken for disposal of these
sources if any.
All the departments using ionizing radiation sources have followed the
IAEA Safety Rules and Standard with care and caution, no radiation
hazard or accident or incident has ever occurred at all.
Safety and radiation protections are being taken as much as possible to
comply with relevant IAEA regulations.
Radioactive waste generated outside the territory of the Republic of the
Union of Myanmar shall not be imported into the Republic of the Union of
Myanmar for any purpose.
Experiences and knowledge will gain from this training and will be useful
in implementing Waste Management Programme in Myanmar.
THANK YOU VERY MUCH
FOR
YOUR ATTENTION
