| Abstract:: |
| Objective To study the calculational method for the radiotherapy facilities of the medical linear accelerator's useful beam towars its maze. Methods The shielding calculation was made under the relevant national standards for a radiotherapy treatment room and compared with the test results. Results The dose rates at the maze entrance as calculated and measured were 89 and 86 μSv/h inside the maze door, as well as 5.7 and 6.2 μSv/h outside the maze door, respectively. The calculated results were consistent with measured results. Conclusions By comparison of calculated results with measured results, the accuracy of the theoretical calculation method could be verified. |
