RADIATION MEASURING INSTRUMENT, ELECTRONIC EQUIPMENT AND PORTABLE TELEPHONE TERMINAL

摘要

PROBLEM TO BE SOLVED: To provide a radiation measuring instrument capable of performing accurate measurement by eliminating the influence of noise.SOLUTION: A radiation measuring instrument 1 according to this invention includes a radiation detection unit 2 and a radiation amount calculation unit 3. The radiation detection unit 2 includes radiation sensors 4a and 4b for outputting an electric signal in accordance with incidence of radiation, and a pulse output circuit unit 5 for outputting a pulse in the case where a value corresponding to a signal obtained by subtracting an output signal of the radiation sensor 4a from an output signal of the radiation sensor 4b is not within a predetermined range.
