Abstract: We made an attempt to measure the scattering dose of space, surface, and deep region focusing on organs that are sensitive to radiation during CT examination and compare their characteristics. Methods/Statistical analysis: To conduct the experiment, we used 64-Slice MDCT for CT Scanner and Rando Phantom. For dose measurement, first, we used a Survey meter to measure space scattering dose, second, to measure incident surface dose, we used OSLD nanodot, and third, to measure deep dose, we used a glass dosimeter.The choice of the location for the measurement of radiation dose was based on organs that are susceptible to radiation, namely Orbit for Head, Breast for Chest, and Godnad for Abdomen.Findings: In the head CT scan, at breast,the space dose was 48.2 ± 0.34 μSv, the surface dose was 82.0 ± 2.29 μSv and the deep dose was 376.0 ± 1.58 μSv. In the Gonad, the space dose was 9.7 ± 0.02 μSv, the surface dose was 20.0 ± 1.36 μSv, and the deep dose was 12.0 ± 1.27μSv. In the chest CT scan, at orbit,the space dose was 229.0 ± 2.85 μSv, the surface dose was 167.0 ± 1.27 μSv and the deep dose was 506.0 ± 1.58 μSv. In the Gonad, the space dose was 72.6 ± 0.41 μSv, the surface dose was 96.9 ± 1.53 μSv, and the deep dose was 190.0 ± 1.58μSv. In the abdomen CT scan, at orbit,the space dose was 68.7 ± 0.34 μSv, the surface dose was 72.0 ± 1.36 μSv and the deep dose was 224.0 ± 1.58 μSv. In the Breast, the space dose was 145.2 ± 1.57 μSv, the surface dose was 4597.0 ± 1.27 μSv, and the deep dose was 9137.0 ± 1.27μSv Improvements/Applications: It seems necessary to make constant efforts to reduce the dose of radiation by optimizing the radiation protection by blocking the space other than the main flux.
