CHEM 418 Nuclear Chemistry, Winter 2016: 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.

    I sent the lecture 10 pdf quiz as an attachment through email.
    It is really nice to have a full explanation on the questions section at the end of the lecture.
    Thank you

      Thanks. I thought some examples on using stopping power would be helpful.

      Yes. It definitely helpful to answer the concept. Thank you. I hope it will also have a full explanation on the question session in the following lectures.

    I found the lecture very interesting, it was a bit different from what we had been discussing and more application related.

      This is more applied. Definitely using the information in a different manner. This is also the last nuclear focused lecture. The next lectures start on exploring chemistry. Some will be review, but I suspect the chemistry of the actinides will be new.
