The new style nuclear plate which controlled ray sensitivity is created, and the neutron-spectrum measurement technique under a high ray background is developed. The track length of the recoil proton of the neutron reason recorded on a nuclear plate checked that the response function was evaluated and a neutron spectrum could be evaluated by unfolding from track length since it is dependent on the energy of a neutron.
