First of all, many models of this machine, particularly the cheaper ones, were not adequately shielded to prevent the radiation from leaking out in all directions. Oh, and then there’s the shoddy construction of these machines. To put that into greater perspective, exposure of 200 mSv might start to irreparably damage your chromosomes, 300 mSv could stunt a child’s growth, and 350 mSv would’ve gotten you evacuated from Chornobyl. These fluoroscopes, operated by an untrained shoe store employee, might give a customer a dose of anywhere from 100-1,160 mSv. Look at it this way: A typical CT scan administered by trained professionals under the controlled conditions of a hospital’s radiology lab would give a patient a dose of 1-10 millisieverts (mSv) of radiation. It depends on the make and model of the machine, and over 15,000 of them were sold worldwide in the eleven years before governmental agencies started regulating their use. How much more are we talking about? It’s difficult to say. A fluoroscope like this is more of a live feed, meaning the user would be exposed to more radiation for way longer than an X-ray. An X-ray is a still image developed on a sheet of film, done in a short period of time in order to minimize the radiation exposure to the user. Well, calling it an X-ray is not exactly accurate. Once the machine was turned on, the customer and salesperson could then peer into the view panels and see an X-ray of the customer’s feet to determine how cramped the customer’s toes were inside the shoes. The machine’s use was pretty simple: a customer would try on a new pair of shoes, stand on the machine, and place their feet in the holes on the base. That is a shoe-fitting fluoroscope, which was invented in 1919 and started showing up in shoe stores the following year.
