Marie Curie: Nobel Prize-winning female scientist

 Marie Curie: Nobel Prize-winning female scientist whose notebooks cannot be touched without protection for the next century and a half

The most important documents of scientific history are preserved in special boxes made of several layers of lead in the National Library of France.

If a scientist wants to use these documents, he can study them only by wearing heavy protective suits like astronauts.

But before this study they have to sign a special document that the library will not be responsible for any situation that happened to them.

This is one of the oldest and rarest books in the world.

But the reasons why they are kept in such a dubious manner are actually more important than the scientific significance of these documents.

Because these papers are contaminated with highly radioactive material.

These are Marie Curie's notebooks, the only two-time Nobel laureate who, along with her husband Peg, not only discovered new chemical elements but also uncovered the natural principles of atomic physics and radiation.

And just like everything else that this couple had, these documents can be very harmful to humans.

Marie Curie and her husband discovered polonium  and radium. It was named after Poland, where Mary was born on November 7, 1867. But until then, scientists had no idea of ​​the possible effects of radiation on the human body.

In fact, Marie Curie died in 1934 from a disease called A-Plastic Anemia, which may have been caused by her regular exposure to radium and polonium. My curiosity often carried this stuff in my pockets.

So everything related to them, which is still intact, is very carefully kept in lead boxes, even his own body, which is the 'Pantheons of Paris' cemetery dedicated to the famous people of Paris. in. Marie Curie was the first woman to be buried in this cemetery

When his body was taken there, an inch-thick coffin of lead was made to prevent radiation from the body of the "mother of modern physics" from polluting the environment.

Scientists believe that this will always be the case, and that notebooks will remain unprotected for at least the next 1500 years, as long as the effects of radium, discovered by Marie Curie and the world-changing element, 

Dangerous house 

There is a three-story building in a residential area south of Paris that is off-limits.

A high protective wall filled with barbed wire makes it impossible to enter the house. The surroundings are constantly monitored by cameras so that no one tries to enter, while the government periodically monitors the environment with strange devices.

But this house is empty. This is the last laboratory where Marie Curie worked since 1990's 

Scientific experiments conducted by Marie Curie have contaminated the area with radiation that will keep it unsafe for life for many centuries to come.

Many years after the death of Marie Curie when high levels of radiation were found here , it was dubbed the "Chernobyl of the Sain River."

This place was used as the headquarters of the Institute of Nuclear Physics and the office of the Faculty of Science at the University of Paris to pay tribute to Marie Curie before radiation was discovered here.

It was later discovered that radiation was present in the walls, carpets, floors, ceilings and even wallpapers of the house and its levels were unsafely high for humans.

And here, for the rest of my life, Marie Curie continued to work on the world's most harmful substances, such as thorium, uranium and polonium, without any precautionary measures.

He wrote in his autobiography that he enjoyed watching the green and blue flashes coming out of these substances at night.

And at the time of working on these radioactive substances, she would write about them in her notebook and make sketches, and  all these things became contaminated with radioactive substances.

Many years after his death, the United States became the first country to ban the commercial use of these substances in 1938, after which other countries followed suit.

Since the discovery of Marie Curie and the awards she received ,this hurt many industries,  radioactive materials became so popular so they were used to make face creams, razors and even underwear. These substances are thought to prevent hair loss and treat male infertility.

According to media reports at the time, several neighbors complained of rising cancer cases in their area.but his laboratory was not evacuated until the 1980s, 

One study found not only radium but also uranium particles that take four and a half billion years to disintegrate.

Marie Curie's items, which are considered national heritage, including her notebook, were then transferred to the National Library.

Since 1990's his laboratory was cleaned again in the but French authorities still barred him from entering, and periodically surveyed surrounding areas, including the river.

It is estimated that France has so far spent  10 million on cleaning up the site, and more is expected to follow when the site collapses in the coming years.

However, these notebooks will remain locked in lead boxes for more than the next one and a half thousand years, with the hope that the people of the future will be able to carry the notebooks of the most intelligent woman in human history without a protective suit.
