A simple and rapid method of determining the thermal neutron absorption cross section of rocks

Description

A new method of determining the macroscopic thermal neutron absorption cross section of rock samples is described. Due to simplicity and rapidity it is suitable for routine application. The method uses samples of volume of about 1400cm3 and a measuring set-up consisting of moderating block, Pu-Be neutron source emitting roughly 5x105n/s, BF3 proportional counter and ordinary counting equipment. The method has been tested with a set of artificial rock samples. 95% confidence intervals of about 0.27m-1 have been estimated for 2x300s counting times. Results of measurements for several natural rock samples agree with those obtained by pulsed neutron technique. (author)
