摘要：
A new method for measuring the flux density and fluence of fast neutrons in a RBMK core, using a threshold ionization fission chamber with a 238U radiator, and a computational-experimental method based on threshold chambers for fissioning of 238U with enrichment at least 99.999% are proposed. A method is proposed for taking account of the correction factors for the change in sensitivity of threshold fission chambers with and without screens on the basis of RBMK-1000 fast-neutron spectra determined experimentally by the activation method.
