The method defines a general procedure for determining an unknown thermal neutron-flux density by neutron activation techniques. The method is presented so that the user may adapt to his particular situation the fundamental procedures of the following techniques: technique using pure cobalt metal and cobalt-aluminum alloy; standard foil technique using pure gold; and secondary standard foil techniques using pure indium, indium-aluminum alloy, and dysprosium-aluminum alloy. The techniques are limited to measurement at room temperatures, but special problems encountered when making thermal-neutron flux measurements in high-temperature environments are discussed. (JMT)
