Interesting. In short, in 1945, Kodak X-ray film was irradiated en route to hospitals and clouded. Thanks to radioactive isotopes in the packing cardboard. The isotopes first came from rivers near the paper mills.

QuoteKodak first learned of radioactive isotopes in their cardboard in August 1945, shortly after the Trinity nuclear test on July 16, 1945. Customers reported fogging and black spots on X-ray film, which Kodak traced to contaminated strawboard packaging produced on August 6, 1945, at their mill in Vincennes, Indiana. Physicist Julian H. Webb investigated and identified the contamination as wind-borne radioactive fission products, likely cerium-141, from the Trinity test.
