The article tells about who discovered the phenomenon of radioactivity, when it happened and under what circumstances.
The Modern world and the industry is unlikely to be able to do without nuclear energy. Nuclear reactors nourish submarines provide electricity to entire cities, and special energy sources based on radioactive decay, are installed on artificial satellites and robots that explore other planets.
The Radioactivity was opened in the end of XIX century. However, like many other important discoveries in various fields of science. But who are the scientists first discovered the phenomenon of radioactivity and how it happened? This is what we will discuss in this article.
This is a very important scientific event happened in 1896 and made his A. Becquerel while studying the possible relationship of luminescence and recently opened the so-called x-rays.
According to the memoirs of Becquerel, he came up with the idea that, maybe, any luminescence is also accompanied by x-rays? To check his hunch, he used several chemical compounds, including one of salts of uranium, which glowed in the dark. Then, holding it under the sunlight, he wrapped the salt in dark paper and put it in the closet on a photographic plate, which, in turn, were Packed in a lightproof wrapper. Later, showing her the Becquerel replaced the exact image of a piece of salt. But since luminescence to overcome the paper couldn't, so he turned on the plate that is x-ray radiation. So now we know who first discovered the phenomenon of radioactivity. However, the scientist himself did not yet fully understand what made the discovery. But about all under the order.

Later in the same year, at a meeting of the Academy of Sciences of Paris, Becquerel made a report “the radiation produced by phosphorescence”. But after a while his theory and conclusions have had to make adjustments. So, during one of the trials, not waiting for nice and Sunny weather, the scientist put on the photographic plate is the compound of uranium which light was not irradiated. Nevertheless, the album still reflected a clear structure.
The Second of March of the same year, Becquerel presented to the meeting of the Academy of Sciences a new job, which described the radiation emitted by phosphorescent bodies. We now know of the scientists who discovered the phenomenon of radioactivity.
Doing further research of the phenomenon of radioactivity, Becquerel tried a lot of substances, including uranium metal. And every time on the plate remained traces. And by placing between the radiation source and plate metal crucifix, he received, as we would say, his x-ray. So we discussed the question of who discovered the phenomenon of radioactivity.
It was then that it became clear that Becquerel discovered a completely new type of invisible rays that can pass through any objects, but at the same time, they were not x-ray.
It was Also found that the intensity of radiation depends on the amount of uranium in the chemical preparations, and not from their types. It is the Becquerel shared his scientific achievements and theories and their spouses Pierre and Marie Curie, who later established a radioactivity emitted by thorium, and discovered two completely new element, later called polonium and radium. And parsing the question “who discovered the phenomenon of radioactivity” often, many mistakenly credited with the merit of the spouses Curie.
When it became known that the radiation emit all the compounds of uranium, Becquerel gradually returned to the study of phosphor. But he made another important discovery-the effect of radioactive rays on biological organisms. So Becquerel was not only the first who discovered the phenomenon of radioactivity, but also to those who has established his influence on living beings.
For one of the lectures he borrowed a radioactive substance the curies and put it in his pocket. After the lecture, returning it to its owners, the scientist noticed severe redness of the skin, which had the shape of the tube. Pierre Curie, after hearing his guess, decided to experiment – for ten watches worn tied to the arm tube containing the radium. And in the end received a severe ulcer that wouldn't heal for several months.
So we discussed the question of the scientists who first discovered the phenomenon of radioactivity. This was openly the impact of radioactivity on biological organisms. But despite this, the curies, by the way, continued to study radioactive materials, Marie Curie died from radiation sickness. Her personal belongings are still kept in a special lead-lined vault, as they accumulated dose of radiation nearly a hundred years ago is still too dangerous.
