Radioactivity and Radiation Interactions (PHYS*3170)
Code and section: PHYS*3170*01
Term: Fall 2021
Instructor: Ralf Gellert
Office: MacN 450
Tuesdays & Thursdays 11:30 − 12:50, MCKN 316
This course introduces the student to concepts in radiation physics with underlying emphasis on its practical application in medical physics. Topics include: atomic and nuclear structure, introduction to different types of radiation and their reaction mechanisms, natural and artificially generated radioisotopes, the interaction of radiation with matter, radioactive decay processes, human dosimetry calculations and external radiation shielding. This course is meant to provide the student with the capacity to carry out calculations in this field and provide context to material taught in upper level physics courses.
(1 of IPS*1510, Math*1210, Math*2080) and (Math*2170 or Math*2270)
James E. Turner, "Atoms, Radiation, and Radiation Protection", 3rd ed., John Wiley & Sons, 2007. The textbook can be used as supporting reading material during the course; however, the course will not follow the order of the material. This text is available electronically as an ebook through the library website, search primo for Turner and radiation.
The weekly short online quizzes will probe the material discussed throughout the semester. The 5 assignments will be posted on the courselink site typically 10 days before the due date. Your work can be handed in as papers or as a merged pdf file through a dropbox folder. Late assignments will be deducted 10% per day. No assignments can be accepted after the posting of the solutions typically 2 days after the due date. Contact the instructor well in advance if your submission is delayed due to excusable circumstances.
Midterm and Final Exam
The midterm and final exams will be in class. Only under justifiable circumstances a remote exam through respondus at the same time slot will be considered. The midterm date will be coordinated with all other third- and fourth-year courses. The final exam is scheduled for Dec 13, 2021, 14:30-16:30 by the registrar. Both the midterm and final exam will be closed book. You will be provided with an equation sheet in advance, and you are allowed to prepare a one-page, handwritten cheat sheet. Usual non-programmable pocket calculators will be permitted.
If you miss the midterm exam due to illness or compassionate reasons, you need to provide the instructor with a waiver slip. See your Program Counsellor if you require assistance. If you miss the final examination, see your Program Counsellor. Please refer to “Process for Academic Consideration and Appeals” in the 2021/22 Undergraduate Calendar.
By the end of this course, you should be familiar with:
- Basics of nuclear physics that explains natural occurring and artificially produced radioactive elements and their decay mechanisms
- The different types of radiation and their interaction with matter and living cells
- The concepts and application of dose and exposure to assess the damaging effects of radiation on cells and organisms
- Applications of nuclear physics in medicine (diagnosis and treatments) and science
The following schedule provides a rough guide of the material covered during the semester.
|Week 1||Introduction, nuclear physics and binding energy|
|Week 2||Coulomb barrier, decays modes|
|Week 3||Decay chains|
|Week 4||Interaction of charged particles with matter|
|Week 5||Interaction of photons (x-rays, \(\gamma\)) with matter, x-ray tubes, shielding|
|Week 6||Energy fluence, dose|
|Week 7||Interaction of neutrons with matter|
|Week 10||Equivalent and effective dose|
|Week 11||Application of nuclear physics in medical diagnostics and treatment|
|Week 12||Reviews before midterms and finals|
It is required to regularly check the Courselink webpage, where quizzes, lecture material, notes, assignments and solutions and further materials or announcements are posted. The typical weekly short quizzes will probe and solidify the main concepts and materials covered in that week. They are intended to entice students to keep up with the course material throughout the semester.
(Not) Working With Other Students
All work submitted for grading in this course must be each individual student's own work. While students are encouraged to share thoughts and ideas, it is not acceptable to share assignment solutions. The work on the assignments, i.e. to start filling the blank paper with calculations based on the concepts and examples discussed in the lectures, is an essential step in the solid understanding of the material and crucial for the preparation for the exams.
Tentatively, an hour on Tuesday and Thursday, the instructor will be available in the office, MacN 451 and through zoom. Additional meetings can be arranged through email or discussion in the lectures.
The course website is on CourseLink Desire to Learn (D2L) website. All students registered in this course have access through their University of Guelph Central Login account.

The University of Guelph takes a serious view of academic misconduct and will severely penalize students, faculty and staff who are found guilty of offenses associated with misappropriation of others' work, misrepresentation of personal performance and fraud, improper access to scholarly resources, and obstructing others in pursuit of their academic endeavours. Each student is assumed to be familiar with the regulations surrounding academic misconducts, as spelled out in the Undergraduate Calendar.
Course and Instructor evaluation
The Department of Physics requires student assessment of all courses taught by the Department. These assessments provide essential feedback to faculty on their teaching by identifying both strengths and possible areas of improvement. In addition, annual student assessment of teaching provides part of the information used by the Department Tenure and Promotion Committee in evaluating the faculty member's contribution in the area of teaching.
The Department's teaching evaluation questionnaire invites student response both through numerically quantifiable data, and written student comments. In conformity with University of Guelph Faculty Policy, the Department Tenure and Promotions Committee only considers comments signed by students or by choosing \I agree" in question 14 (online process). Your instructor will see all signed and unsigned comments after final grades are submitted. Written student comments may also be used in support of a nomination for internal and external teaching awards.
NOTE: No information will be passed on to the instructor until after the final grades have been submitted.
Inappropriate online behaviour will not be tolerated. Examples of inappropriate online behaviour include:
- Posting inflammatory messages about your instructor or fellow students
- Using obscene or offensive language online

- Adapting information from the Internet without using proper citations or references
- Buying or selling term papers or assignments
- Posting or selling course materials to course notes websites
- Having someone else complete your quiz or completing a quiz for/with another student
- Stating false claims about lost quiz answers or other assignment submissions
