X-rays will "Fog" photographic plates. That means the plates act as if 'exposed' to light. If the X-rays are intense enough, the plates will appear to be totally exposed.

When did Nikola Tesla invent x rays?
Tesla reported that, driven by his observation of mysterious damage to photographic plates in his laboratory, he began his investigation of x-rays at that time still unknown and unnamed in 1894.
What detector is used to pick up the x-rays in hospitals?
photographic film
How to tell if your growth plates are damaged?
A physician would be able to determine if growth plates are damaged by doing X-rays.
What does the x in X-ray mean?
Wilhelm Röntgen was the one who gave them the name "X-rays", though many referred to these as "Röntgen rays" for several decades after their discovery. The presence of some unknown ray was deduced from its effect on photographic film/plates when sealed in light tight containers. Röntgen referred to the radiation as "X", to indicate that it was an unknown type of radiation. The name stuck, although (over Röntgen's great objections) many of his colleagues suggested calling them Röntgen rays. They are still referred to as such in many languages, including German.
What atomic number is 47 used to make photographic film?
The element with atomic number 47 is Silver (Ag). It is used in photographic film, as well as solar panels, water filtration, X-rays, and disinfectants.
How do you make an x-ray?
Because most X-rays pass through the skin and other body tissue, the X-ray strikes the photographic film beneath the area. unlike other body tissues, bones absorb X-rays
How did Watson and Crick find the structure of DNA?
Crick was high on LSD when he had the idea of a double helix. Photographic x-rays confirmed his discovery when the image displayed an X shape, indicating a helix.
How do radioactive nuclides affect photographic film wrapped in light proof paper?
Gamma radiation can easily pass through paper and cause fogging on film. This is radiation identical to light except it has higher frequency and energy, generally higher than x-rays.
How does density affect X-rays?
The speed of passage of the x-radiation through a body depends on density.
What are facts about Marie Curie that changed the world?
Marie Curie is famous for discovering the element Radium, previously unknown. The history of this is an interesting progression, like so much in science. The physicist Roentgen discovered X-rays, and found that they would pass through solid matter, and also that they would affect photographic plates. The scientist Becquerel discovered that a mineral called pitchblende would affect these plates even through their wrappers, and suspected that the mineral was producing X-rays. This was puzzling, because Roentgen made X-rays using high voltages in a vacuum chamber, while pitchblende just sat there but somehow did the trick. Curie thought that there must be something unknown in pitchblende. She bought tons of it, and started trying to isolate something else from it. Eventually she managed to get a few grams of something from the tons of original stuff. This new substance were remarkable It was always warmer than its surroundings; it shone in the dark, and it produced something very like X-rays. The rate at which these three things were produced did not seem to diminish with time. She had produced a radioactive substance with a long half-life. Because it radiated light, heat and X-rays it became called Radium.She discovered the properties in radium, polonuim, and uranium. She also found out the properties in X-rays were able to kill tumors.
X rays radio waves?
X-rays have a higher frequency; therefore, a shorter wavelength, than radio waves. Xrays have a higher energy than radio waves. Radio waves travel easily through the atmosphere. X-rays suffer significant attenuation passing through the atmosphere. Radio waves are non-ionizing, not carrying enough energy per quantum to ionize atoms or molecules-that is, to completely remove an electron from an atom or molecule. The electromagnetic radiation of radio waves has sufficient energy only for excitation, the movement of an electron to a higher energy state. X-rays are ionizing, producing charged ions when passing through matter. X-rays will deposit images on photographic plates (radio waves will not).
How radiation discovered?
In 1896 Henri Becquerel was using naturally fluorescent minerals to study the properties of x-rays, which had been discovered in 1895 by Wilhelm Roentgen. He exposed potassium uranyl sulfate to sunlight and then placed it on photographic plates wrapped in black paper, believing that the uranium absorbed the sun's energy and then emitted it as x-rays. This hypothesis was disproved on the 26th-27th of February, when his experiment "failed" because it was overcast in Paris. For some reason, Becquerel decided to develop his photographic plates anyway. To his surprise, the images were strong and clear, proving that the uranium emitted radiation without an external source of energy such as the sun. Becquerel had discovered radioactivity. Becquerel showed that the radiation he discovered could not be x-rays. X-rays are neutral and cannot be bent in a magnetic field. The new radiation was bent by the magnetic field so that the radiation must be charged and different than x-rays. When different radioactive substances were put in the magnetic field, they deflected in different directions or not at all, showing that there were three classes of radioactivity: negative, positive, and electrically neutral So basically radiation was discovered by accident
