There is a high potential that your hairdresser has more educational and licensing requirements than the person taking your X-rays.

I work in healthcare, and in many states employees are allowed to utilize ionizing radiation with zero training or educational requirements. This allows employers to pay substandard wages, and compromise patient safety in the name of corporate profits. Please take the time to write your governors and demand licensure through the ARRT, and approriate educational requirements. This will dramatically increase wages and improve patient safety. https://www.usa.gov/state-governor
