소개글

"방사선상호작용 - 광자 상호작용 (Photon Interactions)"에 대한 내용입니다.

목차

1. Photon
2. Compton scattering
3. Klein-Nishina cross section
4. Photoelectric absorption and Pair production
5. Total interaction coefficients

본문내용

1. Photon
Photons are classified according to their origin (not their energy)
 From nucleus: Gamma rays
 From acceleration of charged particles: Bremsstrahlung radiations
 From atomic transitions of bound electrons: Characteristic X-rays
 From combination of positron and negatron: Annihilation photons

<중 략>

There are three major interactions:
 Photoelectric absorption ( low energy)
 C ompton Scattering (=incoherent scattering, medium energy)
 Pair production ( high energy)
