context:Radium-226 and radium-228 in solution as a consumer tonic dates from the early commercial radium-medicine era of the 1910s and 1920s. Bailey Radium Laboratories standardized the Radithor formulation in 1925, marketing it through cooperating physicians and direct mail order. Radium-226 is a naturally occurring decay product of uranium-238; radium-228 is a decay product of thorium-232 (sometimes called 'mesothorium' in period literature). Both isotopes emit high-energy alpha radiation; radium-226 has a half-life of approximately 1,600 years, radium-228 of approximately 5.75 years.

MECHANISM CLAIMED

Low-dose radium ingestion stimulates the endocrine system, increases cellular metabolism, and produces general 'vitality' and restoration in the recipient through the radium's energetic effect on metabolic processes.

MECHANISM ACTUAL

Ingested radium isotopes are absorbed from the gastrointestinal tract and deposited in skeletal tissue, where they substitute for calcium in bone hydroxyapatite. The deposited radium emits high-energy alpha radiation locally over years to decades, causing progressive osteonecrosis (especially of the jaw and skull), radiation-induced bone cancers, anemia, and marrow failure. Cumulative skeletal burdens above approximately 2 micrograms are fatal. Eben Byers's autopsy and exhumation analysis (Robley Evans, 1965) estimated a total lifetime radium intake of approximately 1,000 microcuries (37 MBq), an order of magnitude above the lethal threshold.

NOTES

Radium-226 and radium-228 in water were the active material of Radithor and of the broader category of ‘mild radium therapy’ consumer tonics sold in the United States and elsewhere in the late 1920s. The mechanism Bailey claimed (low-dose radiogenic stimulation of endocrine and metabolic function) is empty: ingested radium causes progressive skeletal destruction and radiation-induced cancers, not ‘mild’ stimulation. The ingredient is the canonical example of a consumer-tonic active material whose harm was unrecognized at the time of marketing and demonstrated only through fatal patient outcomes during the practice’s commercial life. The use of radium isotopes for human consumption is now prohibited internationally; the case contributed materially to the modern FDA’s authority over patent medicines and radioactive substances.
