ydintoiminta
Ydintoiminta, literally “nuclear activity” in Finnish, refers to the processes and activities that involve atomic nuclei. In physics it covers natural and artificial nuclear phenomena such as radioactive decay (alpha, beta, gamma), nuclear reactions (fission, fusion, neutron capture), and the related transport, transmutation, and detection methods. The field is broadly divided into fundamental nuclear physics, nuclear reaction physics, reactor physics, and radiation protection.
The scope includes both theoretical and experimental work, including studies of nuclear structure, decay schemes, reaction
Safety, regulation, and public policy are integral to ydintoiminta. In Finland, oversight is provided by the
