ABSTRAK

 

IAEA dalam penerbitannya tahun 2000 telah mengesyorkan satu helaian kerja untuk menentukan dos terserap kepada air dalam alur electron. Helaian kerja ini dinilai melalui satu kerja penentuan dos terserap kepada air di satu Pusat radioterapi tempatan menggunakan satu alur electron 12 MeV. Sekiranya beberapa pengubahsuai dibuat, helaian kerja IAEA ini akan menjadi lebih mesra pengguna dan dapat mempermudahkan dan mempercepatkan lagi proses audit jaminan kualiti.  Pengubahsuaian ini diberikan dan dibincangkan.

 

Kata kunci:  helaian kerja IAEA, penentuan dos terserap

 

 

ABSTRACT

 

IAEA in its publication year 2000 has recommended a worksheet for the determination of absorbed dose to water in an electron beam.  We evaluated the worksheet via an absorbed dose to water determination work at a local radiotherapy center using a 12 MeV electron beam. We found that if several modifications are made, this IAEA worksheet will become more user-friendly and could facilitate and fasten the process of quality assurance audit. The modifications are given and discussed.

 

Keywords: IAEA worksheet, determination of absorbed dose
