Radiation and quack medical products have a long and infamous history. The Oak Ridge National Laboratory, America’s premiere nuclear research institute, keeps a list of discontinued radioactive snake-oil. Distributors looking to make a quick buck have claimed radiation could keep teeth brighter, reduce the amount of tar in cigarettes, and cure arthritis. The latest twist: ionized cock rings to “maintain fuller erections,” “stay harder longer,” and “enjoy intense orgasms.”

The products come from ShenZhen Yek Technology Co., a Chinese manufacturer that sells products like “cell phone anti radiation quantum shields” and an ion producing card that promises to save you money on your electric bills. The cock rings aren’t advertised as radioactive, but as full of negative ions. In its product picture, a cock ring sits on an “ion tester.” A geiger counter is a device that detects ionizing radiation. Selling an item as producing negative ions is a way to rebrand radioactivity as a health benefit.
