Analysis of Tube Leakage of X-Ray Radiation Using Geiger Muller Sensor Equipped with Data Storage

Abstract

X-ray radiation (ionization) cannot be felt directly by the five human senses. Therefore, radiation monitoring is needed, one of which by using a survey meter. The purpose of this research is to directly monitor the level of radiation exposure and leakage of X-ray tube containers in the work area. This was done to ensure the safety and health of workers in the radiation transmission area, so that it is in accordance with the ALARA (As Low As Reasonably Achievable) principle, which is stipulated in the Decree of the Minister of Health RI No. 1250/Menkes/SK/XII/2009 concerning Guidelines for Quality Control of Radiodiagnostic Equipment as Standard Values ​​for X-Ray Radiation Monitoring. This research is an experimental study with a survey meter equipment module design using a Geiger Muller sensor equipped with data storage. This module design method uses Arduino programming as data processing and is displayed on the CHARACTER LCD. Test analysis was carried out by comparing the measurement value of the module with the standard value as a standard for comparison. Based on the measurement results, the X-ray tube leak test value resulted in a standard AAT survey meter value of 0.001 both using a closed and unsupplied 2mm Pb circuit, namely 0.00097 mGy/hour and 0.00092 mGy/hour. Meanwhile, the results of the tube leakage test using a survey meter, both circuits, modules, and standard survey meters show a passing grade test value of < 1mGy/hour. In conclusion, the module design using the Geiger Muller sensor is feasible to use.

The Evaluation of Complementary Metal-Oxide Semiconductor (CMOS) in Smartphone to Test X-Ray Tube Radiation Leakage

“…The front area of the tube was a common highest leak area of the tube. Utomo et al, shown from his research that the highest radiation leakage was from the front area which is proportional to this study [29]. From the data above, it can be interpreted that radiation leakage from x-ray tube is in line with previous research.…”

“…The smartphones count were 0.02 μGy/h, 0.16 μGy/h, and 0 μGy/h. The result was contradicted with the study conducted by Utomo et al which the lowest radiation leakage area was the rear [29]. The highest radiation count by surveymeter is at the front of the tube which was 21.14 μGy/h, as for the smartphones count were 2.32 μGy/h, 0.23 μGy/h, and 0.31 μGy/h.…”
