Dosimetric Conformity of Cobalt-60 (Co) Beams
Objective: The radiation dosimetry is the output measurement of radiation generating source/ machine and its ambition is to ensure that the teletherapy units’ outputs are within limits. In the current article, the dosimetry of Cobalt-60 (Co 60 ) teletherapy units at Nuclear Institute of Medicine and Radiotherapy (NIMRA), Jamshoro Pakistan was studied. As Co 60 is undergo decay process, the outp...
متن کاملNew formula for Calculation of Cobalt-60 Percent Depth Dose
Introduction: On the basis of percent depth dose (PDD) calculation, the application of dosimetry in radiotherapy has an important role to play in reducing the chance of tumor recurrence. The aim of this study is to introduce a new formula for calculating the centeral axis percent depth doses of Cobalt-60 beam. Materials and Methods: In the present study, based on ...
متن کاملDose measurement of cobalt-60 radiotherapy beams in treatment fields.
BACKGROUND Radiation-therapy is a complex process with multiple steps, each of which has an impact on the quality of treatment. Accurate dosimetry is a critical step during the radiotherapy of cancer patients.The aim of the present study was to measure and evaluate the doses of two cobalt- 60 (60Co) teletherapy units GWXJ80 of NPIC China and Theratron 780 of AECL Canada at various points within...
متن کاملComparison between Amperometric and Chemiluminescence methods in detection and dosimetry of cobalt-60 gamma ray emission
Background: Hydrogen peroxide (H2O2), produced by gamma ray irradiation to watery solution, was used as an analytical parameter for dosimetry of cobalt-60 (60Co) radiation. Materials and Methods: Detection of the produced H2O2 was carried out using two methods: an amperometric biosensor fabricated by immobilization of anthraquinone 2-carboxylic acid modified horseradish peroxidase on glassy car...
