US Army researched the health effects of radioactivity in St Louis 1945-1970 (2011)

Historical military experiments and ethics

• Commenters highlight past abuses: plutonium injections into unwitting patients, radioactive “vitamins” for pregnant women, Tuskegee, secret aerosol tests in US and Canada, and biological simulant releases like Operation Sea-Spray.
• Many see the St. Louis work as part of a broader pattern of governments experimenting on marginalized or captive populations (e.g., Black communities, “the projects,” mental patients).
• Several emphasize that experimenters viewed themselves as doing “greater good” science, not cartoon villains, which makes repetition more likely.

Oversight, ethics committees, and research progress

• Some argue modern ethics boards are overbearing and slow trivial, low‑risk studies, a “system over-correction” from past abuses.
• Others counter that strong oversight prevents harm, maintains public trust, and filters out sloppy or unnecessary experiments.
• Debate centers on tradeoffs: delayed treatments vs. preventing exploitation; everyone agrees some balance is needed, but pruning checklists is rare.

Radiation risk, radon, and hormesis

• Thread discusses radon baths and “radiation hormesis.”
• One side: no safe level of radon or radiation exposure; any dose adds risk, “safe levels” are economic compromises.
• Others say consensus is not settled, citing correlations of higher background radiation with lower cancer rates and possible hormesis, while still not endorsing intentional exposure.
• Specific claims like radon scratching windows are discussed, with citations and requests for sources; some skepticism remains.

St. Louis and ongoing contamination

• Locals mention current radioactive waste issues: West Lake Landfill, underground fires, Coldwater Creek, and contamination at a local elementary school.
• There is frustration at limited transparency from agencies and perceived minimization of health risks despite cancer clusters and documented findings.

Government secrecy, trust, and vaccine skepticism

• Many link these revelations to present-day distrust of institutions, especially around vaccines and public health campaigns.
• Some argue that, given this history, skepticism and refusal (e.g., COVID vaccines, mandates) can be rational, especially for communities previously harmed.
• Others insist current vaccine development and Manhattan‑era programs are operationally distinct, warning against conflating all government actions.

Scope of the St. Louis aerosol tests

• Official story: zinc cadmium sulfide used as a dispersion simulant for chemical/biological weapons.
• Some commenters claim additional radioactive or nuclear‑related components and tandem secret studies; others say the dissertation’s evidence here is weak or “just vibes,” though later media and political statements are cited as partial confirmation.
• Overall, the exact substances and health impacts remain contested and partially unclear.
