It was located within the Sand Springs Range about 30 miles south east of Fallon, Nevada. Shoal is a DOE site from 1962-1964 so workers are eligible to file for Part B and Part E compensation.
DOL provides Part B and Part E statistics on the Project Shoal site as well as exposure information from their Site Exposure Matrix on Project Shoal.
NIOSH has statistics on dose reconstructions done for Project Shoal workers.
