* The increase in cycles of calculation conducts to increase of reliability of indications.
** Period of observation shortens with the increase of a dose rate more than 3,0 µSv/h.
*** Two batteries with a capacity 1350MAh, at a level of a natural background no more than 0,3 µSv/h and with factory settings.
