The harm of tritium to the human body 20, the harm of tritium to the human body

Tritium is a radioactive isotope of the elemental hydrogen, and its nucleus is composed of one proton and two neutrons. The tritium that is commonly seen in life is the kind you see in the corridor, which is a glowing exit sign, so the question is, will this radioactive substance be harmful to the human body?

Effect on the human body Because the decay of tritium will only release high-speed moving electrons and will not penetrate the human body, only a large amount of tritium will be harmful to the human body. However, it should be noted that tritium-labeled bioactive substances (such as tritium-labeled thymine), due to their biological activity, will be used by human cells for cell metabolism, causing direct internal irradiation, thus seriously endangering the health of inhalers.

The mass of tritium is 3, and in natural hydrogen, the content of tritium is 1 10-15%. 1934, British e.Rutherford and others bombarded the deuterium target with accelerated deuterium nuclei on the accelerator, and found tritium through nuclear reactions, and Lozier and others in the United States confirmed the existence of tritium in heavy water, and in 1939, Alvaret and others in the United States proved that tritium was radioactive.

It is less harmful to the human body, and tritium cannot penetrate **. The tritium that enters the lungs through breathing does not enter the metabolic system and is almost entirely excreted in the urine in a short period of time. The amount of radiation leakage is close to zero during normal use.

A little radioactivity is nothing. Deuterium and tritium are found in most water. There's radon in the air and things like that.

Titium in small doses is basically harmless, but prolonged exposure is certainly harmless. There are tritium-containing springs in Longmen Mountain, Sichuan, where tourists can wash and so on, but the local ** department prohibits the use of these springs to make mineral water in batches for sale, which shows that long-term and large exposure to tritium is still harmful to people.

In 1939, Alvare and others in the United States proved that tritium was radioactive. However, because the decay of tritium only emits high-speed moving electrons and does not penetrate the human body, only a large amount of tritium inhaled will be harmful to the human body.

In general, tritium is not harmful to the human body.

Due to the decay of tritium.

It only emits high-speed moving electrons and does not penetrate the human body, so only a large amount of tritium can be harmful to the human body. However, it is important to note that bioactive substances labeled with tritium (such as tritium-labeled thymine) are used by human cells due to their biological activity.

It is used for cell metabolism, causing direct internal irradiation, which seriously endangers the health of inhalers.

If people drink tritium water, they will feel uncomfortable, tritium water will have a corrosive effect on internal organs, radiation will affect normal thinking, and cause cardiovascular and cerebrovascular diseases, appetite will decrease significantly, and mental strength will deteriorate.

If you drink a large amount, you can go to the hospital for treatment.

There will be a buildup of radioactive elements in the body, and there will be a buildup of radioactive elements in the body.

At present, all schools have started to mail admission notices. The Beijing EMS staff responsible for the delivery of the admission notice reminds that after the candidates obtain the admission results, they should ensure that the reserved ** number is unblocked, so that they can receive their own notices as soon as possible. At the time of delivery, the postal courier logistics staff will be uniformly dressed.

Candidates should prepare their ID cards, admission tickets and other relevant documents in advance. If the candidate is unable to receive the document in person and needs to sign on behalf of others, the person who signs on behalf of the candidate must also prepare a valid ID document in order to successfully complete the signing.

Tritium is a radioactive isotope of hydrogen with a symbol of 3h and a mass of 3, and in natural hydrogen, the content of tritium is 1 10-15%. Its nucleus is made up of one proton and two neutrons, and its properties are very similar to hydrogen.

<>1. Tritium is a radioactive isotope of hydrogen in the form of a proton and two neutrons. Because the decay of tritium will release high-speed moving electrons, although it is inevitable that it will penetrate the human body, if a large amount of tritium is inhaled, it will be harmful to the human body.

It should be noted that tritium-labeled bioactive substances (such as tritium-labeled thymine and erection), due to their biological activity, will be used by human cells for cell metabolism, resulting in direct internal irradiation, which seriously endangers the health of inhalers.

2. In the hydrogen element, Pyne accounts for almost all (; Deuterium occupies only a tiny fraction of the time (and tritium has no place for it. Because the half-life of tritium is so short, tritium formed in the evolution of the universe has died out in the early stage of the evolution of the earth. However, due to the action of cosmic rays, 100-5 million curie equivalent tritium is born in the atmosphere every year, so nature still leaves a footprint of tritium.
