Nuclear reactions do indeed occur in the human body, but the body does not use them. Nuclear reactions can lead to chemical damage, which the body may notice and try to fix

Answer 2

Answer:

are chemical processes and not nuclear processes. Nuclear reactions do indeed occur in the human body, but the body does not use them. Nuclear reactions can lead to chemical damage, which the body may notice and try to fix.

There are three main types of nuclear reactions:

Nuclear fusion: this is the joining of two small atomic nuclei into one nucleus.

Nuclear fission: this is the splitting of one large atomic nucleus into smaller fragments.

Radioactive decay: this is the change of a less stable nucleus to a more stable nucleus.

Nuclear fusion requires high energy in order to be ignited. For this reason, nuclear fusion only occurs in stars, in supernovas, in nuclear fusion bombs, in nuclear fusion experimental reactors, in cosmic ray impacts, and in particle accelerators. Similarly, nuclear fission requires high energy or a large mass of heavy, radioactive elements. For this reason, significant nuclear fission only occurs in supernovas, in nuclear fission bombs, in nuclear fission reactors, in cosmic ray impacts, in particle accelerators, and in a few natural ore deposits. In contrast, radioactive decay happens automatically to unstable nuclei and is therefore much more common.

Radioactive decay produces high-energy radiation that can damage your body. Fortunately, our bodies have mechanisms to clean up the damage caused by radioactivity and high-energy radiation before they become serious. For the average person living a normal life, the amount of radioactivity in his body is so small that the body has no difficulty repairing all the damage. The problem is when the radioactivity levels (the amount of nuclear reactions in and around the body) rise too high and the body cannot keep up with the repairs. In such cases, the victim experiences burns, sickness, cancer, and even death. Exposure to dangerously high levels of radioactivity is rare and is typically avoided through government regulation, training, and education. Common causes of human exposure to high radioactivity include:

Naturally occurring radon in the ground. All forms (isotopes) of the element radon are radioactive. Radon testing in houses has become standard to prevent over-exposure.

Employees working in nuclear reactors or nuclear weapons facilities. Strict policies and personal radiation gauges help prevent over-exposure.

People being too close to a nuclear weapon when it is tested.

People living near a nuclear power plant when it experiences a nuclear disaster.

Medical treatment that uses radioactivity in a controlled way to combat disease.

The natural occurrence of carbon-14 decay in the body is the core principle behind carbon dating. As long as a person is alive and still eating, every carbon-14 atom that decays into a nitrogen atom is replaced on average with a new carbon-14 atom. But once a person dies, he stops replacing the decaying carbon-14 atoms. Slowly the carbon-14 atoms decay to nitrogen without being replaced, so that there is less and less carbon-14 in a dead body. The rate at which carbon-14 decays is constant and well-known, so by measuring the relative amount of carbon-14 in a bone, archeologists can calculate when the person died. All living organisms consume carbon, so carbon dating can be used to date any living organism, and any object made from a living organism. Bones, wood, leather, and even paper can be accurately dated, as long as they first existed within the last 60,000 years. This is all because of the fact that nuclear reactions naturally occur in living organisms.
