DIMENSIONING OF RADIATION RELAYS AND OF LIMITING VALUE SWITCHES OPERATING WITH ISOTOPES
G. Sahner · OSTI OAI (U.S. Department of Energy Office of Scientific and Technical Information) · 1961
The dimensioning of the connection of a radiation relay and the effects to be taken into consideration are detailed for the various operating systems, and the results obtained presented in such a way that such a relay can be adapted reasonably to any measuring problem. The allowance for the statistical stray of the integration voltage calls for some overdimensioning of the connection. Such a relay may be rated so that the danger of incorrect function caused by statistical variations becomes smaller than the danger of failure of an electronic element. The data stated in leaflets, especially the maximum attainable accuracy of measurement, can be accepted with certain qualifications only. Since standard definitions of these parameters are not yet available, the present report is well suited as a proposal for establishing these definitions. The results obtained, however, may also be applied to other appliances. Instruments operating with the use of radioactive isotopes have to record the exceeding of a limiting value. (auth)
