The physics of diagnostic X-rays (AQA A-Level Physics): Flashcards

Heated metal releases free electrons with sufficient energy to escape

Braking radiation producing continuous X-ray spectrum

Line spectrum

$eV_a$ (electron charge × accelerating voltage)

1%

High melting point and thermal conductivity

~3000 rpm

Increases intensity only, not photon energy

Detection plate close, patient still, lead grid reduces scatter

Filters out low-energy photons, reduces skin dose
