the results obtained from all these systems were questicned because of the neutron resvonse of the detector itself, as well as tne inter¢ection of neutrons with the shield used to protect the detectors from blas:s and tnermal radiation. In many cases this interaction vroduced sufficient secondary gamma rays to cause an appreciable increase in the total dose measured by the detector. (U) This report attempts to rectify this situation oy correctirg the initial gamma data for direct neutron interaction with the detect to Ly avai > for or the t t tro eids, and and for the atte the interaction of t neutrons wi th the snields, Stenuatt ion n or the initial gamma rays by the shields. An evaluation of the gamma dose produced by neutron interaction with the ground is also presented Dut not used as a correction since the ground is part of the fixed environ ment. To perform this work the USANDL obtained direct neutron interaction factors for available dosimeter films (References'1, 2, and 3) ard correction factors for the secondary gamm2 radiation produces by neutron interactions with shields and soil (References 4 and 5). Direct neutron interaction factors for glass and chemical systems were obtained oy otner investigaters (References 6,7,8,9, and 10). During Operation Sun 2eam tne theoretical calculations which produced the correction factors for shields and soil were experimentally verified (Refererce 11). (U) Recent work has indicated that these gamma dosimeters are dependent upon dose rate and total dose in a complicated fashion (Reference 12), Much more work will be necessary to clarify this situation. 18
