The risks of X-Rays where understood years before these where banned. https://en.wikipedia.org/wiki/Shoe-fitting_fluoroscope

For context the Radium girls won their lawsuit from 1927. By 1950 the belief was all radiation exposure resulted in increased risks, yet these things where used into the 1970’s.

Hell, the nuclear industry continued to use known inherently unsafe designs. Fukushima wasn’t really a failure due to a tidal wave, it’s a failure due to requirements for active cooling. Inherently safe means turn the lights off and come back in a year and it’s fine, not everything is fine as long as you keep doing X.
