Gen. Leslie Groves, the director of the Manhattan Project, constructed a barrier intended to block legal claims for radiation injuries and illnesses, but it began to crack by the 1980s and now has crumbled. Groves believed that such compensation was a dagger aimed at the heart of the nuclear weapons program. Given widespread radiation exposure problems, concerns over financial and legal liabilities also influenced a wide variety of radiation-protection decisions. According to Stafford Warren, medical advisor to Groves,
an overriding concern was to protect “the government interests” against legal claims. - Barton Hacker, The Dragons Tail, University of California, 1987, p.51.

Even though the preponderance of evidence supports this conclusion, the US government failed to enforce radiation protections for workers while clearly not objecting to conducting syphilis tests on them.  How do I klow this?  Every person I have advocated for across the country from multiple nuclear weapons sites have a complete file of syphilis testing in their medical files.  Dosimetry - lucky if it is even available.
