* Increase of tests number results in indications reliability growth. 

** Two batteries with capacity of 1350 mAhour at natural background level not exceeding 0.3 mcSv/hour, provided manufacturer’s settings of the instrument are preserved. 

*** Characteristics were obtained as a result of research performed by Centre of Ionizing Radiations Metrology assigned to the State Scientific and Metrologic Centre (VNIIFTRI) in the period from the 1^st to the 8^th December 2005 and approved by reports dated 14.12.2005.

 Verification of the metrological characteristics of indicators of radioactivity party is done by certified radioactive sources:
