An analysis based on Fermi age approximation is used to explore the feasibility of using neutron migration phenomena to monitor the consistency, and possibly also the fiber density, in pulpwood-water slurries of the type processed in the pulp and paper industry. The results of preliminary experimental work are also presented. A significant experimental result is that the consistency of a 3 percent mixture of sulfite pulp in water may be monitored with a relative precision of ± 3 percent (or ±0.09 percentage points) in a sampling time of 1 s.
