Radiation Attenuation Formula: I = i0e^-ud Explained

The formula I = i0e^-ud represents the intensity of radiation after passing through a material of thickness 'd' and attenuation coefficient 'u'. 'I' is the final intensity, 'i0' is the initial intensity, and 'e' is the mathematical constant known as Euler's number. The exponent '-ud' describes the amount of attenuation or loss of radiation as it passes through the material.
