Clinical services

Medical physics is a combination of applied physics, engineering and medicine. This unit has physics science officers who are responsible for the radiotherapy unit, the nuclear medicine unit, and the radiology unit. The main responsibility of this unit is to ensure that the laws under the Akta Perlesenan Tenaga Atom 1984 (Akta 304) is practiced at all times in AMDI. The medical physics unit offers expertise and consultation in all matters related to radiation safety, radiologically related accidents at the work place, specifications of personal protective equipment, radioactive waste management, as well as continuous medical education related to x-ray and Act 304.

Services
This unit is in charge of performing quality control and calibration on x-ray instruments that are registed with MOH to ensure that it reaches the standards set by MOH. This unit also makes sure that the registered employees undergo a health examination, as well as submit copies of their APC and CME annually for record purposes. They enlist the help of the Malaysian Nuclear Agency to calibrate the physics equipments such as the pocket dosimeter, and they also advice departments/centers/units on all aspects related to x-ray in the work place.
This unit also holds the X-Ray Protection Program in AMDI where they offer their expertise in x-ray and radioative material waste management. They serve as a Crisis Coordinator in the event of accidents involving radiological material or spills. This unit also functions as a bridge between the different units who require their advice.
