The effects of gamma radiation on neutron counting with in-core ion chambers and the range of neutron flux measurable in the RMS voltage mode are discussed. An example of ranges covered by a single detector is 5 x 10/sup 6/ to 5 x 10/sup 13/ nv or 7 decades. This is possible with the short, fully-enriched ion chamber and in a gamma field of 5 x 10/sup 5/ r/hr. Gamma noise was found to spread the pulse spectrum. Results of experiments are presented in graphs and tables. (M.C.G.)
