Abstract
1534461 Remote measurement of radiation ELECTRIC POWER RESEARCH INSTITUTE Inc 5 Aug 1977 [30 Sept 1976] 32866/77 Heading G1A [Also in Division H4] Radio-activity is measured by a detector, such as a scintillation counter 14, producing a voltage proportional to the radiation energy; the detector signal is amplified, converted to serial digital form, and then converted to tones by a modem 20 for transmission via a telephone mouthpiece 22. The transmitted signals are passed via receiver 26 to modem 30 for conversion back to serial digital form, and thence via D/A converter to a pulse height analyzer 34. The energy spectrum of radiation source is split into 256 levels, each of which is represented by a 10 bit word, one bit being for a parity check and another for synchronizing modem 30; about 120 levels can be transmitted per second on normal telephone equipment, which is less than the maximum information rate that analyzer 34 can handle. The analyzer can therefore be used to analyze the radiation from several sources simultaneously by duplicating parts 14-32.
