Neutron dosimetry had been performed at the Nevada Test Site using NTA film or albedo LiF TLDs. In 1987 the dosimeter type was changed from albedo TLDs to the CR-39 track-etch system. This paper reports on the use of track-etch dosimeters at the NTS, including some of the problems encountered in the original processing system, calibration and quality control issues, and changes made to optimize and partially automate the system. While the CR-39 track-etch system is very labor intensive, with expensive quality control requirements, it is attractive for situations where exposures of small magnitude, affecting a few people, come from high-energy neutrons.
