The use of large NaI(T1) crystals and large Ge (Li) diodes to make -in -sit u measurements of y-rays from sources in the soil and air is described. Methods for inferring source concentrations and contributions to the total exposure rate from individual emitters are discussed and tables of photon flux to source activity and flux to exposure rate conversion factors are presented. Descriptions are given of the Calibration of 4 in. by 4 in. NaI (T1) detectors, and 25 cm³ and 60 cm³ Ge(Li) diodes. A number of applications of field spectrometry are discussed.
