Biomedical Engineering > GATE 2024 > X-Ray Attenuation
An X-ray beam of initial intensity I0 of 70 keV imaging the chest is assumed to undergo attenuation through the muscle tissue for a thickness of 16 cm and further through the bone tissue for a thickness of 4 cm. The half value layer (HVL) thicknesses for the muscle and bone are 3.5 cm and 1.8 cm, respectively. The percentage of X-ray intensity transmitted through the body is _________ Give your answer rounded off to 2 decimal places.
