CHEM 418 Nuclear Chemistry, Winter 2019: Lecture 10 Radiation Interactions

This lecture, in 2 parts, covers interaction of radiation with matter and includes fundamental interactions, particle ranges, dosimetry, and hot atom chemistry. Interaction of radiation with matter covers energy loss and reactions with charged particles and photons. The stopping power of charged particles in different material is covered, including calculations on energy loss with thickness. Electron backscattering is introduced with examples on different behavior with varied elements. Discussion on photon interaction includes photoelectric effect, Compton effect, and pair production. Units of dosimetry are described. Dosimetry measurements are discussed and quality factors based on particle mass and charge are introduced. Introductory dose calculations are supplied. Radiation protection regulations and the definition of terms (ALI, DAC) are given. A review of hot atom chemistry is given. Part 1 is 28 minutes, part 2 is 40 minutes.
The lecture is assigned on Thursday 7 February and due Tuesday 12 February.  ActionThe answers to the Lecture 10 PDF quiz will be posted Wednesday 13 February.
