Abstract: The radiological diagnostic unit explores the patient's internal anatomy and lesion by using an x-ray, which is a non-invasion diagnostic. However, in some parts of the body which is the same type of tissue and cavitation, the lesion cannot be determined clearly. Therefore, medical chemicals have to be used to increase the difference in the area that is called contrast media such as barium sulfate investigate the quan. Rany investigate the Gastrointestinal system. Sometimes, pound (BaSO4) that is used to sulfate is expired and cannot be used for clinical examination. They must also be e disposed of in a standardized way to reduce their impact on the environment, which is very costly and budgetary that the hospital or medical service center has to bear. In this way, the research team has the idea to waste barium sulfate that cannot be used in medicine but is still intact. Developed as the main material for repairing such damage, barium has the properties of reducing radiation by mixing it with a resin that has restorative properties which makes the barium- resin composite material. The research team has determined the suitability of barium-resin proportions that are 70:30 (30 pieces), 60:40 (30 pieces) and 50:50 (29 pieces) and those are measured to find composited material density ( p material) are 2.21993 g/cm3, 1.95568 g/cm3 and 1.72655 g/cm3 respectively. Moreover, all composites were taken to measure the radiation attenuation values (Linear) at different X-ray energy at the Office of Atoms for Peace of Thailand. The Linear of 70:30 proportion are 3.367 and 2.785 by using 100 kV 6 mA and 120 kV 9 mA respectively and 60:40 proportion are 3.261 and 2.555 by using 100 kV 6 mA and 120 kV 9 mA respectively and 50:50 proportion are 3.921, 2.651 and 2.076 by using 80 kV 4 mA, 100 kV 6 mA and 120 kV 9 mA respectively. In conclusion, the Pmaterial and the Linear will increase when barium proportion is more than resin proportion which is considered under the same x-ray energy or setting parameter technique (for the μLinear). However, the Linear of 70:30 and 60:40 unable to detect at 80 kV 4 mA because that x- ray energy cannot penetrate the composited material to the radiation detector. So, the HLinear of 70:30 and 60:40 at 80 kV 4 mA cannot be calculated. However, in practice, the proper Barium-Resin proportions that can be easily mixed and used is 60:40.
