The research has been carried out on the HVL and TVL values of the primary and secondary walls of the radiology installation radiology room at RSU Bali Jimbaran. The aims of this study were (1) to determine HVL and TVL values on the primary and secondary walls in the x-ray room, (2) to determine the differences between HVL and TVL values if the tube voltages are varied. In determining the HVL and TVL values, the linear attenuation coefficient of the walls must be known. The linear attenuation coefficient was determined by measuring the wall thickness by using a caliper, and measuring the radiation dose rate before and after passing through the primary and secondary walls. The results of the analysis of the HVL and TVL values on the primary wall were 1.668 cm and 5.540 cm, meanwhile on the secondary wall were 1.915 cm and 6.362 cm. When the voltage was varied 40 kV, 50 kV, 60 kV and 70 kV, there was no difference in the HVL or TVL values. Based on the results of the analysis, the HVL and TVL values on the primary and secondary walls have a significant average difference.

“…Beside the positivity of it, the use of X-ray may give a negative impact or side effect. In this case, if a person gets exposed to X-rays continuously, the amount of radiation will be accumulated on that body and may be interfered with its health [1][2][3][4].…”
