The Detection of High Energy Radiation - Measurement of Flux Density and Spectra

First an outline of the principal methods of high energy physics to detect and to discriminate different particles within an unknown particle field is given. After that the instruments for Health Physics purposes are dealt with in some detail. Time-of-flight methods, spark chambers, Bonner spheres and activation detectors are reviewed with respect to particle energies of 1 to about 1000 MeV.
