The 50s and 60s were called the atom age. The power of atom was seen as the future, and if you ask me we should continue our pursuit for atom energy, despite the idiotic oposition of uneducated hipsters and brain washed environmentalists.

One of the pioneers of usage of radioactive materials in automotive research was Ford. For studying the use of atom in the vehicle production chain they've built a large underground bunker-lab at the River Rouge plant. 

The scientists studied radioactive materials with the help of special remote control equipment. And the first results showed up in the first part of 1950. The radioactive material helped determine the level of molten metals in cupolas and measure and control the thickness of sheet steel.
