A Study on Horizontal Scatter Radiation with Phantom when Irradiated by X-ray
Keywords:
scatter radiation, x-ray, radiation scatter contourAbstract
The objective of this study was to assess scattered radiation distribution exposed to the phantom that represent head and body patient by diagnostic x-ray, dental x-ray and mammogram. It was conducted by measuring scatter radiation plane from the phantom using Ray Safe Model 452 survey meter. The finding revealed that plot contour with universal kriging type of Interpolation method in Program Surfer 7.0. Irradiation in x-ray instruments showed different contours. First, circle in diagnostic x-ray and reduce intensity of scatter radiation by distance was detected. Next, intensity near tube in dental x-ray reduced by distance and a few irradiation was detected at posterior tube. Finally, mass radiation intensity was recorded in front of mammography x-ray. The results of contours map from the x-ray machine could be used as a guide to control point for irradiation safety.
