Abstract

The accuracy of the dose rate of accelerators for radiotherapy is very important, it is directly related to the results of cancer treatment. This paper presents process dose calibrate for evaluating dose accuracy of the dose rate of photons emitted from a linear accelerator (LINAC) in Dong Nai General Hospital. The samples Thermo luminescent Dose (TLD) of Agency International Atomic Energy (IAEA) provided irradiated with 2 Gy absorbed dose on the LINAC at Hospital. Then, the samples are sent back to the IAEA to analyze and evaluate error. The results compare standard doses with errors less than 5% and in the range of allowed radiation. The results also showed that the radiation on accelerator in Dong Nai Hospital is credible.

Highlights

In 1969, the Agency International Atomic Energy (IAEA) and theWorld Health Organization (WHO) set the project to send the samples Thermo luminescent Dose (TLD) by mailed to calibrate the radiation beam at the developing countries, This project applied to more than 3300 radiotherapy centers all around the world

Summary

INTRODUCTION

World Health Organization (WHO) set the project to send the samples TLD by mailed to calibrate the radiation beam at the developing countries, This project applied to more than 3300 radiotherapy centers all around the world. In the process of benchmarking has discovered many errors and has recommended treatment time during calibration. In Vietnam, this project in collaboration with the Institute of Atomic Energy Vietnam has been conducted in most of the radiation facility in the country. Dong Nai General Hospital enjoy in the first round of benchmarking in March 2013. The initial results, it was encouraging us in work measurement, quality assurance of radiation therapy accelerator LINAC
