Radiation Interaction, 7.5 Credits

Contents

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 comprises three modules
1. Theoretical part, 2.5 credits
2. Calculation part, 2.5 credits
3. Laboratory work, 2.5 credits

Required Knowledge

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/6. Where the language of instruction is Swedish, applicants must prove proficiency in Swedish to the level required for basic eligibility for higher studies.

Form of instruction

The teaching is campus-based and is conducted in the form of lectures, calculation exercises, laboratories and seminars. Laboratories and seminars are compulsory. The language of instruction is Swedish or English.

Examination modes

Part 1: Theoretical part 2.5 credits
The part is examined with written exam. The grade is  assessed with Fail (U), Pass (G), Pass with merit (VG).

Part 2: Calculation part 2.5 credits.
The part is examined with written exam. The grade is assessed with Fail (U), Pass (G), Pass with merit (VG).

Part 3: Laboratory work 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 (G), Pass with merit (VG) 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 module1 and 2, where module 1 is given a weighting factor of 1/2  and module 2 a weighting factor of 1/2, and is set after all mandatory elements are approved.

Students who received a passing grade on an examination may not retake the examination.
 
Deviations from the course syllabus examination form can be made for a student who has a decision on pedagogical support due to disability. Individual adaptation of the examination form should be considered based on the student's needs. The examination form is adapted within the framework of the expected syllabus of the course syllabus. At the request of the student, the course responsible teacher, in consultation with the examiner, must promptly decide on the adapted examination form. The decision must then be communicated to the student.

A student who has passed two tests for a course or part of a course without a passing result, has the right to have another examiner appointed, unless there are special reasons against it (HF ch. 6 § 22). The request for a new examiner is made to the head of the Department of Radiation Sciences. For more information, see Rules for grades and examinations at basic and advanced level, dnr: FS 1.1-574-22.
 

Other regulations

In the event that the syllabus ceases to apply or undergoes major changes, students are guaranteed at least three examinations (including the regular examination opportunity) according to the regulations in the syllabus that the student was originally registered on for a period of a maximum of two years from the time that the previous syllabus ceased to apply or that the course ended.
