X-rays - 1940 - How Little We Knew

I recently found this old black and white video of a scientist explaining x-rays to a non-science audience. It's interesting and a bit scary to realize how little people knew about the positive and negative effects of radiation at that time. It makes me realize that we must be cautious when using seemingly fantastic new technologies. I love trying new science tools, methods, and materials more than most, but this video is a reminder that hazards and side effects can be unknown until additional research is done.
