γ-specific-activitimeter H-90B is a portable microcomputer-digitized 4-channel integrated γ-spectro-meter for measuring spcific activity of nuclide. It is characterized by functions to automatically stablilze the γ-spectra, and to automatically measure at a given time. It can be used both to automatically calculate contents of 40K，U and Th, and to fast measure the specific activity of natural radioactive nuclides 226Ra,232Th and 40K in stones and architecture materials and industrial wastes on-the-spot.
