Syllabus:	Waves and vibrations - review of simple harmonic motion. Damped simple harmonic motion, non-linear systems. Forced oscillations, transient and steady state terms. Coupled oscillations, normal modes of vibration. Transverse waves, reflection and transmission coefficients. Longitudinal waves. Radiation physics - Detection methods, gas filled detectors. ionisation chamber, proportional counter, GM counter, dead time, quenching. Scintillation counters, semiconductor devices [Ge(Li), Si(Li). Detection efficiency, energy resolution. Spectroscopy, pulse height analysis, nuclear spectroscopy, application to mineral exploration and medical diagnosis. Measurement statistics. Radioanalytical techniques, use of radioactive tracers in medical imaging, industrial processes, biological studies. Non-destructive elemental analysis using, charge particle activation, PIXE, applications to - surface concentration, depth profile analysis.

Unit Outcomes:	On successful completion of this unit students will be able to highlight the strong link between physics and mathematics in classical mechanics and have developed a robust problem solving technique suited to multi-layered problems. More specifically, they will be able to explain the principles of gas filled detectors, scintillation detectors and solid state detectors, demonstrate an understanding of pulse height analysis and explain its applications to industrial and medical applications and explain anddescribe the radiation dosimetry terms.
