Abstract

A shield for a well logging instrument includes an outer layer including a reinforcing fiber disposed in a matrix and an inner layer including a thermal neutron absorbing material disposed in a matrix. The thermal neutron absorbing material is selected to emit capture gamma rays having energy outside a selected energy range.
