Read the wording for your board, then hide it and explain Attenuation measurements along many paths in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
Detectors measure the transmitted intensity after the beam has passed through the body, and comparing this with the incident intensity gives the attenuation along each path.
