Radiographic imaging of Aluminum objects at varying distances using Americium-241 decay

Abstract

Radiographic imaging has several medical, security, and industrial applications. In this study, an envelope imaging system using Americium-241 was developed to explore the effect of distance from sensor to radioactive source on image quality. Results show that increasing the distance led to a decrease in image quality. There was also a significant visibility of the object at a distance of 1.5 cm. An inverse relation between distance and signal to noise ratio was also observed. Radiation intensity was influenced by the inverse square law. The work can be further explored by optimizing distance for image quality and relating it to practical applications such as internal defect detection.
