Exponential attenuation of X-rays
What Exponential attenuation of X-rays means in Physics A-Level, as defined for OCR.
Definition of Exponential attenuation of X-rays
Check what you remember
Read the wording for your board, then hide it and explain Exponential attenuation of X-rays in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
The attenuation of a collimated X-ray beam follows I = I₀e^(−μx), where I₀ is the incident intensity, I is the transmitted intensity, x is the absorber thickness and μ is the attenuation coefficient.
