Nonionizing radiation, the stuff of microwave, infrared and visible light doesn’t have the energy needed to break chemical bonds, so we may sit out in the sun and get bombarded with a thousand watts and feel no ill effects. Once we reach ultraviolet tho

The 2x2A is a vacuum rectifier that, before the advent of the silicon diode, was used to rectify the high voltage needed for fun things such as television tubes. Now the silicon diode replaced the 2×2 nearly 40 years ago at the time of this writing, but

Invented in 1913 by William D. Coolidge, the Coolidge tube is by far the most popular method used to generate x-rays. Essentially it’s just a thermionic diode, but one optimized for high voltages and high powers. Like a thermionic diode a Coolidge tube

The goal of this project was to build an inexpensive portable x-ray machine, since such a device didn’t seem to exist! Odd, since such a machine could prove to be very useful in remote or underequipped areas such as army camps or poorer countries. T

In 1895, a professor by the name of Wilhelm Conrad Rontgen discovered a source of invisible rays which were capable of penetrating materials not normally translucent to ordinary light. Not only this, but these mysterious rays also caused certain chemicals
