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.
All done with the lecture and quiz. My favorite part of this lecture was learning the rad safety levels and the max amount of radionuclide materials we could use in the lab based on the associated ALI.
ReplyDeleteI just finished the lecture and quiz. I felt that this lecture was very straightforward and the radiation safety was interesting to get a refresher on.
ReplyDeleteI've finished the lecture and quiz. It's too bad the general public only learns what they know about radiation from the media, because public perception of this stuff is very negative. I thought it was an interesting and useful lecture with good application. Thanks!
ReplyDeleteFinished lecture and quiz. E-mailed the quiz directly because I guess some of mine were not being submitted correctly. I agree with most of the above comments, overall interesting and enjoyable lecture.
ReplyDeleteDone with lecture and quiz. Thanks for making it easy right before spring break!
ReplyDeleteI have completed and submitted the quiz as of now. It's interesting to see a simple molecule such was water undergo many different secondary reactions after it has been ionized, and the lecture in general has helped me understand the effects of radiation more now than previously.
ReplyDeleteFinished the lecture and the quiz. It was interesting to see how much of a sample you can work with for a given condition.
