NUCLEAR AND RADIOCHEMISTRY TEACHING IN EUROPE


PROPOSAL OF MINIMUM REQUIREMENTS FOR A MASTER’S DEGREE IN
NUCLEAR AND RADIOCHEMISTRY – TOWARDS EUROPEAN MASTER’S DEGREE
EU project CINCH (Cooperation in education in nuclear chemistry) - http://cinch-project.eu/

Minimum Requirements for a MSc in Radiochemistry

(as defined by the CINCH consortium) 



In the following, minimum requirements for nuclear and radiochemistry teaching in the European
universities are outlined for MSc level. The plan is intended to form a basis for European master’s
degree in nuclear and radiochemistry (or European master's degree in chemistry - specialization in
nuclear and radiochemistry). The status of the degree can be granted on the basis of mutual
agreement with participating universities or by a decision of an external body such as EuCheMS.
Teaching can consist of lecture and laboratory exercise modules as well as of exams.


Structure of MSc programme on nuclear and radiochemistry (NRC)
BSc in chemistry 180 cu
Mandatory studies on nuclear and radiochemistry 25 cu
(of which at least 10 cu exercises)
Optional studies on nuclear and radiochemistry 5 cu
Project work and master’s thesis in nuclear and radiochemistry 30 cu
Other studies rest
In total 300 cu
Mandatory studies on nuclear and radiochemistry (25 cu)
In the following topic areas (1-6) and under them topics that need to be covered are listed. The topic
areas do not refer to any specific courses which can be organised in various ways. The biggest
challenge in conducting a uniform teaching program in various universities is their capability to
organise laboratory exercises in a sufficient way. Some universities having radiochemistry teaching
are not able to handle any alpha emitting radionuclides and some universities cannot even deal with
any radioactive material. Another big problem is the variation of radiation detection and
measurement apparatuses.
