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
What else can I help you with?
What is the name of the radiation belts surrounding the earth that were discovered in 1958?
The radiation belts surrounding the Earth that were discovered in 1958 are known as the Van Allen Belts, named after physicist James Van Allen who led the team responsible for their discovery. These belts are regions of highly energetic charged particles held in place by Earth's magnetic field.
Which flyby satellite launched by the US discovered a second radiation belt around Earth?
pioneer 3
What did Penzias and Wilson discover?
Penzias and Wilson discovered the cosmic microwave background radiation in 1965, providing strong evidence for the Big Bang theory of the origin of the universe. This discovery earned them the Nobel Prize in Physics in 1978.
How was Cosmic Microwave background radiation first discovered?
It as predicted from theory and discovered by accident by two telephone engineers that, when they saw it, thought it was some sort of interference noise in their instrument, (possibly caused by pigeons). When they were unable to eliminate the noise, they spoke about it to an academic friend who realised that what they were detecting may be the predicted microwave background radiation.
Who discovered infrared radiation?
Sunburn has been around for many centuries.
Who thought of radiation?
Nobody thought of radiation. It was discovered.
Who discovered gamma radiation?
Gamma radiation was discovered by French chemist Paul Villard in 1900 during his studies of uranium.
Who discovered cosmic radiation?
Richard Mewaldt.
James clerk maxwell discovered that light is a form of what radiation?
It is a form of electromagnetic radiation.
What year was ultraviolet radiation discovered?
in 300 BCE
Who discovered the particle theory of radiation?
Neils Bohr
Who is the madame who discovered radiation?
Madame Marie Curie
Who discovered the evidence of cosmic background radiation?
The cosmic background radiation was discovered in 1964 by American radio astronomers Arno Penzias and Robert Wilson
Where was mendelevium discovered?
Mendelevium was discovered at the, Radiation Laboratory of the University of California in Berkeley, California Madison Jacob
Was Marie Curie a scientist?
yes, she is a scientist and discovered radiation.
How was this radiation discovered?
Radiation was discovered by Wilhelm Rontgen in 1895, when he noticed that certain invisible rays were able to pass through objects and create images on a photographic plate. This led to the introduction of X-rays and the discovery of the broader field of radiation.
What month did Arno Penzias's discover background radiation?
Penzias and Wilson discovered background radiation on October 7,1965.
