  Nuclear physics experiments are always in need of more and more advanced
detection systems. During the last years relevant technological developments
have come out with many improvements in terms of performance and compactness of
detector materials, transducers, electronics, computing and data transmission.
In light of these achievements some applications previously prohibitive, mainly
because of size and cost, have become feasible. A few applications of nuclear
detection techniques are discussed, starting from the neighboring field of
particle beam diagnostics, moving to the medical diagnostics and ending up into
the radioactive waste handling. New radiation sensors are shown and explained,
as exploited in the DMNR project for the radioactive waste online monitoring
which merged into the MICADO Euratom project.
