Evaluation of dose equivalent using a tissue-equivalent ionization chamber and a Geiger-Müller dosimeter

Summary

When detailed neutron energy spectrum data are lacking for a mixed field of neutrons and photons, it is permissible when estimating the dose equivalent to assume that the quality factor for the neutrons is 10. With this assumption, it is shown that the responses of a tissue-equivalent ionization chamber and a Geiger-Müller dosimeter can be used to obtain an acceptable approximation of the dose equivalent in the mixed field without requiring precise knowledge of the relative neutron sensitivity of the Geiger-Müller dosimeter.
