Zusammenfassung:	PURPOSE:To simplify an electronic circuit, by a method wherein the mica treated by gamma rays or electron beam is irradiated large amount of neutron rays to change the heat resistance thereof and the neutron rays reaching about 10 neutron/cm is measured utilizing the changes in the heat resistance. CONSTITUTION:After irradiated with about 1,000 megarad of gamma rays or electron beam, a mica sample is irradiated with neutrons in a nuclear reactor, with the result that the heat resistance thereof changes depending on the irradiation time of the neutron rays. Utilizing this, neutrons below about 10 neutron/cm can be measured.
