Development of National Dose Registry: Malaysia Experience

Regulation 5 of Atomic Energy Licensing (Basic Safety Radiation Protection) Regulations 2010 enforced by the Atomic Energy Licensing Board (AELB), require the licensee to ensure that any work involving occupational exposure is adequately supervised and all reasonable steps have been taken to ensure that the radiation protection program, safety procedures, protective measures and safety provisions are observed. In this regard, the licensee is responsible to arrange the assessment of the occupational exposure of workers on the basis of personnel monitoring, where appropriate, using the dosimetry services as approved by AELB. Currently, in Malaysia, there are three occupational dose assessment service providers/ dosimetry service providers i.e. Malaysia Nuclear Agency, Sinaran Utama, and Alypz Sdn. Bhd. Additionally, Regulation 22(4) of Atomic Energy Licensing (Basic Safety Radiation Protection) Regulations 2010 require the licensee to measure the personnel monitoring for external exposure by using one or more approved personnel monitoring devices, carried continuously on the person, which is either Thermoluminescent Dosemeter (TLD), Radiophotoluminescence (RPL) Dosimetry, or Optical Stimulated Luminescence Dosimeter (OSL). When a worker occupationally receives an exposure exceeding 100 mSv, the licensee as employer shall ensure that such worker undergoes a medical examination and investigation by an approved registered medical practitioner.
