Calorimetry may be considered like a technique of nuclear measurement.
Associated with gammametry, it can insure the management of nuclear m
aterial emitting alpha, beta and gamma rays. The gamma spectrometer us
ing a high purety germanium detector can describe the isotopic composi
tion of the sample and the differential calorimeter with thermopile me
asure the equivalent heating from the nuclear properties of these isot
opes.
