Roentgen realized that the energy emitted by the cathode ray tube could travel through most substances, including human skin. However, the rays could not pass through bone and left a shadow of the bone's shape behind it. Within one month of discovery, this new technology was being adopted and implemented in the medical and dental communities.

Prolonged exposure to X-rays can be harmful to human health. As a result, strict guidelines have been established to minimize the risks associated with X-rays.
