    "publication_year": 1958,
    "device_name": null,
    "goal": "Demonstrate that transmutation and induced radioactivity can be used to recover uranium oxide and to synthesize radioactive materials artificially.",
    "problem_addressed": "Need for a method to extract and concentrate uranium and other radioactive isotopes from surrounding materials and to prove that matter can be transmuted under controlled conditions.",
    "concept_summary": "The authors describe experiments in which metal plates charged to a high negative potential are exposed to the emanation (radioactive particles) of thorium. The particles deposit on the metal, dramatically increasing its surface radioactivity (up to ten-thousand-fold). Heating or chemical treatment of the activated metal releases the radioactivity, which can then be collected or used to induce further reactions. The paper argues that such induced radioactivity is a general property of all matter and can be harnessed for ionic recovery of uranium oxide.",
    "detailed_description": "Experiments include: (1) placing a metal plate charged at high voltage inside a sealed vessel containing thorium emanation, resulting in intense surface radioactivity; (2) demonstrating that the radioactivity persists for weeks and can be transferred to other bodies; (3) showing that heating a radioactive metal causes loss of radioactivity that spreads to neighboring objects; (4) noting that certain chemicals (e.g., sulphuric acid, quinine sulphate) become temporarily radioactive after heating; (5) proposing that the phenomenon is due to charged particles adhering to surfaces and that the effect can be amplified by folding metal into cylinders to trap radioactive products. The authors extrapolate these observations to a universal principle of matter dissociation and transmutation.",
