Personal Monitoring Service (PMS)
The occupational exposure control program is implemented for the protection and safety of radiation workers in medicine, industry, research, and other radiation applications. The program is designed to be compatible with internationally formulated guidelines and standards.
Technical requirements to ensure the safety of radiation workers as per the IAEA general safety standards; GSR part 3 (Radiation Protection and Safety of Radiation Sources: International Basic Safety Standards General Safety Requirements) and IAEA guideline GSG 7 (IAEA General Safety Guidelines) have been adopted in the occupational exposure control program. These standards and guidelines are scientifically-backed by the findings of UNSCEAR (United Nations Scientific Committee on the Effects of Atomic Radiation), ICRP (International Commission for Radiation Protection), IRPA (International Radiation Protection Association) and WHO (World Health Organization).
Also, the program is compatible with the existing national regulations; “Regulations on Ionizing Radiation Protection of the Atomic Energy Safety Regulations No. 1 of 1999”
Personal Monitoring Services Laboratory (PMSL)
There are around 2000 radiation workers in the country who work in medicine (radiologists, radiotherapists, oncologists, etc.), industry (radiographers, irradiator operators, NDT personnel, etc.) and other research fields. According to the national and international guidelines, it is mandatory to provide monitoring services to the radiation workers to ensure their safety and wellbeing.
The personal monitoring service is provided through external dosimetry measurements using Thermo-Luminescence Dosimeters (TLD), a passive radiation-sensitive material in a wearable casing. The main focus is being given to the whole-body dose (radiation dose received by the tissues in 10 mm depth from the surface of the skin). Additionally, eye dosimeters (for eyes) and finger dosimeters (for hands) are also available on request. These extremity dosimeters are
recommended for the workers in particular practices where high-active or open radiation sources are used (nuclear medicine and interventional radiology).
The monitoring service is offered by the Personal Monitoring Service Laboratory (PMSL) of SLAEB. The laboratory and the process have been accredited by Sri Lanka Accreditation Board (SLAB) to be compatible with the ISO/IEC 17025:2017 standards. As an effort to maintain the quality of service, the process undergoes rigorous routine audits, both internal and external. The external assessments are being conducted as verification tests with IAEA accreditation laboratories
The PMS is developing an internal monitoring program for radiation exposure with the assistance of IAEA. The purpose of internal monitoring is to assess the exposure from radioactive material intake, either by inhalation or digestion.

Workplace monitoring service assures the safety of workers working in a radiation facility or with radioactive material. It primarily evaluates the radiation dose and working conditions (related to the utilization of radiation and radioactive material) of the facility. After a detailed survey on radiation levels using ambient gamma, Radon, contamination measurements, and isotopic analysis, workplace conditions are evaluated to produce a detailed report. The survey can be used to identify the necessity of using radiation precautions, monitoring programs, demarking control areas, or improvement of conditions.
Workplace monitoring programs are necessarily recommended for radiation facilities where unshielded sources (liquid or small-particle radioactive material) are being used (e.g., Mineral processing facilities, Iodine treatment facilities, Gamma Imaging Clinics).
Workplace monitoring can also be used to improve workstation safety through radioactive
source identification, categorization, and decontamination of possible contaminants. The
program is based on IAEA international safety standards, WHO recommendations, and ILO
(International Labor Organization) guidelines.
