Annotation of standard text IEC 61275-ed.2.0 :

IEC 61275:2013 is applicable to a portable or transportable photon spectrometry assembly using a high purity germanium (HPGe) detector to survey, in situ, generally at 1 m above ground level, areas in the environment for discrete radionuclides. This standard specifies for such an assembly the general characteristics and test methods for evaluating radiation, electrical, mechanical, safety and environmental characteristics specific to the applications described above. Advice is also provided in annexes as to the calibration, appropriate use and interpretation of the system for in situ measurements. The main technical changes with regard to the previous edition are as follows: - encompass the latest technologies; - revise test methods to account for methodological developments and performance criteria with the latest HPGe detector technologies and digital electronics. La CEI 61275:2013 est applicable a un ensemble portable ou transportable de spectrometrie gamma utilisant un detecteur au germanium de haute purete (HPGe) pour faire un releve, in situ, generalement a 1 m au-dessus du niveau du sol, des radionucleides discrets deposes dans lenvironnement. La presente norme specifie pour un tel ensemble les caracteristiques generales et les methodes dessais pour levaluation des caracteristiques radiologiques, des caracteristiques electriques, mecaniques, de securite et denvironnement specifiques aux applications decrites ci-dessus. Des recommandations sont egalement donnees en annexes pour etalonner, utiliser correctement le systeme et interpreter les mesures in situ. Les principales modifications techniques par rapport a ledition precedente sont les suivantes: - integration des dernieres technologies, - revision des methodes dessai afin de tenir compte des developpements methodologiques et des criteres de performance associes aux technologies les plus recentes de detecteur au germanium de haute purete (HPGe) et delectronique numerique.
