Unusual Applications of NDT and CM

I was rummaging through some old literature the other weekend and found the following article relating to condition monitoring, specifically lubrication analysis, from the 1950s. I think you will agree that it makes for an interesting use of radioactive material and the terminology used was quite amusing, especially the reference to the ‘clucking hen’. Back in the 1950s, there was a lot more home maintenance of vehicles and we can only hope that the experiment wasn’t replicated by amateur mechanics.

There are also stories of radiation being used to check how well your new shoes fit, including one from the web at the Museum of Quackery in the USA about the shoe-fitting X-ray device.
In the late 1940s and early 1950s, the shoe-fitting X-ray unit was a common shoe store sales promotion device and nearly all stores had one. It was estimated that there were 10,000 of these devices in use.

What other unusual applications of non-destructive testing or condition monitoring methods have you come across?
