Location Analysis for Additional Permanent Radiation Detector in X-Ray Radiography Unit

Rizka Indra Prasetya, Gede Bayu Suparta


We have developed a Digital Fluorescence X-Ray Radiography prototype at the Department of Physics, Gadjah Mada University (UGM). The prototype should comply with radiation protection rules. Using an additional permanent dose detector to measure dose radiation indirectly is necessary. We indirectly controlled the dose analysis through a dose control chart from a permanent detector. We consider the Heel Effect in determining the position of the detector at the edge of the screen while reducing the scattered radiation and minimizing the difference to the reference point. The position of the detector follows a grid 5x5. The dose measurement will show the dose distribution pattern. It shows that the radiation dose at the edge point close to the cathode side has the closest dose value to the center point. The dose value variation at 70 kVp and 80 kVp is less than 5%. The dose value equation for the prototype is ï­Gy = [(0.3579* kVp) -16.27] * mAs. A control chart will control that equation from the permanent detector to ensure that the dose value obtained is always valid. The Warning Limit (WL) dose from the control chart is 68.75 ï­Gy, 63.99 ï­Gy, and the Action Limit (AL) is 69.94 ï­Gy and 62.80 ï­Gy. The dose radiation monitoring may use the dose value equation controlled by a control chart from the permanent detector. Continuous reports on the dose value and the limit dose value are essential to ensure the health of the RSFD prototype.
