Device for emitting a first beam of high-energy photons and a second beam of lower-energy photons, and associated method and measuring unit

摘要

This device comprises a single radioactive source (44), capable of creating an incident beam (120), and a target (48) placed opposite the source (44).;The target (48) is capable of creating the second beam (130) by interacting with a first part of the incident beam (120), a second part of the incident beam (120) passing through the target (48) to form the first beam (124).
