What does living cell radiation do?

The effects of radiation on living cells vary depending on the type, exposure and cell intensity. For our purposes, "radiation" concerns ionizing energy emissions such as neutrons, photons and high energy charged particles such as gamma rays. There are a number of different types, including cosmic radiation from space, terrestrial radiation, which is emitted by radioactive elements in the country, and what is caused by man, such as released atomic bomb. For example, in the United States, for example. Millirems, by the way, are units of benefits; They are used to calculate the results of exposure from things such as X -rays in hospitals. The fatal level of exposure varies between individuals and depends on the type of exposure; For example, one exhibition is to dart extended exposures over time. Higher doses can cause the cell to become sterile, or may disrupt the ability of the cell to reproduce properly and cause mutations. For example, many cancers are associated with a radiation exposure that confuseIt takes cells, causing them to mutate and reproduce quickly. At extremely high doses, cell death causes radiation through a process called thermalization, which basically cooks the cell from the inside.

exposure can cause cell damage in two different ways. In the first sense, a direct radiation action, it directly damages the molecule; For example, when radiation disrupts DNA molecule, causing cell damage. It can also cause indirect damage to ionization of molecules and turn them into potentially toxic compounds that interact with healthy molecules and cause damage. Oxygen, hydrogen, nitrogen and carbon are very vulnerable to ionization; Unfortunately for living cells, these elements form a large amount of living organism.

At very high doses, radiation causes massive damage to organs and tissues, which is too extensive to repair the body. This causes acute radiation syndrome, also known as radiationdisease. This condition is often extremely painful and unpleasant and leads to death. At lower doses, the damage may be caused at a finer level and may manifest itself as cancer or through congenital defects caused by damage to reproductive tissues later in life. Some cells are particularly vulnerable damage, especially cells that multiply quickly; That is why pregnant women must be careful about radiation sources, because it can damage the developing fetus.

One of the more dangerous causes of radiation is radioactive isotopes, because these isotopes will accumulate and emit radiation in the body, in clipping with a one -time exposure to radioactive particles, such as parts emitted in the X -ray. For this reason, people who work on radioactive isotopes must be very careful, and those who are used in procedures such as medical imaging have a very short life, which means that they break down quickly and are expressed by the body.
