Course guarantor:

Lecturer:

Jan Bárta, Lenka Prouzová Procházková

Tutor:

Jan Bárta, Lenka Prouzová Procházková

Supervisor:

Department of Nuclear Chemistry

Synopsis:

In these practical exercises, the students will familiarize themselves with the principles of experimental radiation chemistry and photochemistry and obtain knowledge in the practical applications of radiation and photochemical methods for characterization of irradiation sources (chemical dosimetry for determination of dose rate in ionizing radiation sources, chemical actinometry for evaluation of photon flow in non-ionizing radiation sources), syntheses of various inorganic materials (metals, simple oxides, indirect synthesis of multicomponent oxides) and other applications of photochemical reactions.

Requirements:

To obtain assessment, the students must submit to evaluation a laboratory protocol (typically 2-4 pages) for each absolved task, at least 2 weeks before the end of examination period. The protocols will be evaluated and graded or returned with specified corrections required. After all protocols are graded, the student is queried about the tasks performed - their importance and the procedures used. The assessment grade is based on the mean grade of the protocols, possibly modified with regard to the quality of responses to the query.
