In general, there is little or no evidence for disequilibrium in aeolian dune systems, even when the age of the system exceeds 500 ka.However, disequilibrium has been found in several sites subject to wet conditions.As an unsealed radium source, the wearer’s clothing, nutsack, schlong, bedsheets, sexual partners, and probably anything in the vicinity would have been rendered contaminated by Pb-210, Po-210 and other radon daughters. Modern owners of these radioactive collectibles should be cautious about proper storage, as they are among the hotter of the classic quack radium cures.Most important is a hermetic container (e.g., a small dive box) to control radon daughters emitted from the source itself.

To provide more insight into the doses, I downloaded VARSKIN 4, a deterministic radiation transport tool developed for the US NRC often used to model beta doses to skin, and I modeled the geometry and source activity of a Radiendocrinator at the peak of its beta-emitting powers (which occurs when it is 3.5 years old).Radium paint was used for glow-in-the-dark applications from the 1910s through the ’60s.Many people know of the tragedies suffered by early watch dial painters due to ingestion of radium.The Radiendocrinator with its gold-leaf and velvet-lined case.

After dropping out of Harvard without a degree, he briefly engaged in mail fraud, served a prison term, and then entered the lucrative and minimally-regulated patent medicine trade with a fraudulent European doctorate.

Tests for radioactive disequilibrium form part of these measurements.
