The United States Navy Task Force 88 (or TF-88), was formed 28 April 1958. TF-88 was organized solely to conduct "Operation Argus". Once "Argus" was completed, the task force was dissolved, and its records dispersed. Some of these records have been destroyed or lost in the intervening time period. Of particular note among the missing documents were the film records (which recorded radiation levels during the "Argus" tests). This has proved contentious due to the higher-than-normal number of leukemia claims among TF-88 participants to the Veterans Administration. Because of this, it has been difficult to resolve just how much radiation participants were exposed to.
