Fourth, four, ten are ten, what is "carbon-14"?

Nuclear power plant and Helicobacter pylori test

It looks like two areas that can't hit the eight poles

There is a wonderful connection in an element

This element is "Carbon-14"

"Carbon-14" exhalation test

Testing for long -term application of pylori infection

But at present my country's "carbon-14" supply rely on imports

Recently, the world's first batch of commercial piles of "carbon-14" radiation production target parts

Entry in the three factory of Qinshan Nuclear Power Factory of China Nuclear Group

Start large -scale production

It will completely solve the problem of domestic "carbon-14" isotope supply

Qinshan nuclear power operator slowly inserts the target parts into the pile core

What is "Carbon-14"?

What does it have to do with our lives?

Today, Xiaoxin takes everyone a "carbon"

01

What is "Carbon-14"?

Every life on the earth

Based based on four elements

Among them, including hydrogen, oxygen, nitrogen, and more important carbon

So, want to know "carbon-14"

First of all, you need to know the "close relationship" of its carbon element

On Earth

99%of carbon elements exist in the form of "carbon-12"

Common ones such as graphite, diamonds, etc.

About 1%is "Carbon-13"

As for "Carbon-14", there are less

Only about one millionth of about one -millionth

Let's revisit high school physics together first

The number of protons determines the type of element

In the same element

There will be the same proton number

Different numbers of neutron numbers

There are 6 protons in carbon elements

Brothers and sisters who want to identify compatriots

Also count their neutron numbers

For example, "Carbon-12" has 6 neutrons

"Carbon-13" has 7 neutrons

"Carbon-14" has 8 neutrons

Because this proton number is the same

Different characteristics

As a result, the nucleus characteristics of their nucleus are completely different

Different from other brothers and sisters who are dedicated to work "work"

"Carbon-14" is a "active" guy

Maybe it is still busy working with fire eyes at this moment

The next second will be "swimming in the mountains and water" in another form.

So "Carbon-14" has radioactivity

02

What can "Carbon-14" be used to do something?

Since "carbon-14" is radioactive

So it can be detected

So carbon-14 is often used as a mark

Widely used in agriculture, chemistry, medicine, biology and other fields

It is the key to multiple disciplines

For example, in the field of medicine

"Carbon-14" is made into a capsule

People eat the capsule after eating the capsule

You can detect the "carbon-14" content in it

To determine whether the human body contains Helicobacter pylori

In agriculture

Add "Carbon-14" to pesticides

In the later period, the content of "carbon-14" on crops was detected

Let's judge the amount of pesticides

"Carbon-14" is still used for

Measure the concentration of particulate matter in the environment of the environment

Such as PM10, PM2.5, etc.

03

Is "carbon-14" harmful to the human body?

"Carbon-14" has radioactivity

Then use it to detect pylori or add pesticides

Is it harmful to the human body?

my country has a very strict standard of use for "carbon-14"

In fact

We do "Carbon-14" breathing test

The radiation dose caused

Far less than the radiation dose caused by sucking a cigarette

About half an hour of plane

Or eat 12 to 14 bananas.

04

How to artificial "carbon-14"?

With the in-depth application of carbon-14

Its demand is getting bigger and bigger

The current year's pylori test of pylori in my country

More than 30 million people demand

But for various reasons

Although it has been carried out in China

Scientific research work related to the production of medical radioactive isotope

But it has not been able to really form productivity for a long time

Then the problem comes

How did the mass-produced "carbon-14" produced?

Why use a commercial nuclear power unit to produce?

The material of the core of the nuclear power unit

It is a target part of nitrogen -containing elements developed by scientific researchers

Atoms of nitrogen element

There are 7 protons, 7 neutrons

Nitrogen occurs in the reactor nuclear reaction

Will absorb a neutron

Release a proton

forming one

There are 6 protons, new elements of 8 neutrons

This is "Carbon-14"

Long -term high -power operation of nuclear motor group

Can provide stable neutron sources

"Carbon-14" can be continuously generated

And at Qinshan Nuclear Power Station

High neutron flux in heavy water pile crew

Simply put, there are so many neutrons

Therefore, it has a unique advantage in production isotope

"Carbon-14" isotope began to produce on a large scale in Qinshan Nuclear Power

It marks the production of "carbon-14" in my country

Officially opened the road of autonomy

After domesticization

In the future, its output can basically meet domestic needs

Its price will be greatly reduced

It will also help drive the development of the industrial chain of isotope

It is expected that the domestic "carbon-14" will start to supply the market in 2024

"Carbon-14" production opens the road of autonomy

Solved the situation of long -term dependence on imports

It is a central enterprise

Give full play to the role of innovation subjects to continuously improve the ability to innovate technology innovation capabilities

This will further promote the continuous development of the relevant industrial chain

To make positive contributions to help the construction of "healthy China"
