The course starts with a description of the kinematics of photons with matter. The cross section of the processes and their dependent on photon energy, atomic number and density are described in detail. Moreover, a description of charged particle interaction processes, Bethe-Blocks mass stopping power, energy losses in the form of bremsstrahlung cross sections and parameter dependent. The course also includes the principle function of neutrons and X-ray interaction. An Introduction to Monte-Carlo technique applied to ionizing radiation interactions are included.
The course also includes mandatory laboratory work.
The course includes three parts
1. Theoretical part, 2.5 credits
2. Calculation part, 2.5 credits
3. Laboration, 2.5 credits
Knowledge and understanding
Explain the interactions Photo electric effect, Compton scattering, Coherent scattering, Thomson scattering and pair production.
Explain how the atomic cross sections for the above interactions depend on the material's atomic number, density and photon energy.
Explain the relation between the probability and the cross section for an event.
Explain the macroscopic cross sections attenuation-, energy transfer- and energy absorption coefficients and their internal relation.
Explain the interaction of light and heavy charged particles.
Explain the role of the atomic number for the charged particle interaction.
Explain the different parameters in the expression for the stopping power.
Explain the production of bremsstrahlung Explain the shape of the x-ray spectrum and explain in general words the functioning of an x-ray tube.
Explain in general terms for the Monte-Carlo technique and its use of random numbers and cross sections.
Explain the technique for spectroscopic measurements.
Explain the difference between narrow beam and broad beam geometries
Skills and abilities
Calculate the attenuation-, energy transfer- and energy absorption coefficients for molecules based on atomic data.
Calculate the stopping power for molecules based on atomic data.
Calculate the CSDA range for charged particles.
Estimate the energy of charged particles at different depths in a variety of materials Use Monte-Carlo techniques to solve simple, yet analytically not solvable, problems.
Sketch an x-ray spectrum given the acceleration potential and anode material
Validation and approach
Show ability to communicate and cooperation with other participants at laboratory work and other group activities.
Analyse whether experimental, Monte-Carlo and theoretical results are reasonable or not.
University: At least 90 ECTS credits including the courses Atomic and Nuclear Physics 7.5 credits or Nuclear Physics 7.5 credits and Quantum Physics 4.5 credits or corresponding. Proficiency in English equivalent to Swedish upper secondary course English A/5. Where the language of instruction is Swedish, applicants must prove proficiency in Swedish to the level required for basic eligibility for higher studies.
Part 1: Theoretical part 2.5 credits
The part is examined with written exam. The grade is assessed with Fail (U), Pass (3), Pass with Credit (4) or Pass with Distinction (5).
Part 2: Calculation part 2.5 credits.
The part is examined with written exam. The grade is assessed with Fail (U), Pass (3), Pass with Credit (4) or Pass with Distinction (5).
Part 3: Laboration 2.5 credits.
The part is examined with written laboratory report. The grade is assessed with Fail (U) or Pass (G).
On the whole course the grades Fail (U), Pass (3), Pass with Credit (4) or Pass with Distinction (5) are set. To pass the course it requires that all examinations and obligatory tasks are approved. The grade is a summary assessment of the results of the examinations of the different parts, and is set after all mandatory elements are approved.
Students who received a passing grade on an examination may not retake the examination.
Students who do not pass the regular examination renewed examination in accordance with the Umeå University Regulations for tests and examinations at the undergraduate and graduate level (FS 1.1.2-553-14) could be arranged. The first re-test is offered not later than two months after the first examination. When the ordinary examination takes place in May or June, d a first retesting opportunity is given within three months after the first examination. In addition, at least another re-test within one year of regular examination is offered.
In cases where the exam can not be repeated under the current rules for retesting the exam should instead be replaced with another task. The scope and content of such task should not be disproportionate to the missed exam.
A student who has taken two examinations in a course or part of a course without passing, has the right to have another examiner appointed, unless there are specific reasons against it (6 ch. 22, § HF). Requests for new examiners should be addressed to the head of the Department of Radiation Sciences.
In the event that the course expires or major changes are introduced, the students are assured at least three occasions of examination (including regular examination) as prescribed in the syllabus to the course that the student originally registered in over a period of a maximum of two years from the previous syllabus expired.
