How does radioactivity kill?

When electrons are ejected from atoms, they can disrupt chemical bonds, which produces the microscopic and macroscopic damage caused by radiation. Ionizing radiation, by disrupting those chemical connections within our bodies, can kill or damage essential components of our cells, resulting in harm, and at high enough doses...

Can radiation kill animals?

Cells contain intrinsic mending systems that can manage minor damage to a point. However, if an animal cell is exposed to enough ionizing radiation or the damage is severe enough, the cell will die. Radiation can also harm other cells, which can in turn harm an animal. For example, if the heart's own immune system was the only way that heart tissue could defend itself against bacteria, then the radiation from X-rays would be very dangerous. The immune system plays a key role in protecting animals' bodies against infection. It does this by identifying foreign material in the body called antigens and creating antibodies to fight off harmful organisms.

Radiation can come in many forms including ultraviolet (UV) light, X-rays, and radioactive substances such as radon gas and uranium. Animals need sunlight to live but it can also be dangerous if you expose them to too much of it. If you take pictures with your digital camera or use computers at work or at home, you are being exposed to UV rays. This can cause skin problems for those who work close up to their computers or use sunbeds, even though they may be in a room with windows open. These are just some of the many ways in which animals can be harmed by radiation. Radiation can also cause genetic defects in animals' children if they are born alive.

Why is radioactivity dangerous?

Radiation may harm the body's internal chemistry by breaking down chemical interactions in our tissues, destroying cells, and causing DNA damage, all of which can lead to cancer. Radiation may cause disease and death at very high amounts within hours. Low amounts of radiation over many years may also increase your risk of developing other diseases.

The danger comes from any amount of radiation being absorbed by the body. Even if you are not exposed to enough radiation to get sick immediately, it will still have an effect on your health over time. Radiation enters the body through food, air, water, and the skin. The most harmful type of radiation is called ionizing radiation. This includes X-rays, gamma rays, cosmic rays, and radon gas. Other types of radiation include nonionizing radiation such as ultraviolet light and electromagnetic waves such as those used in cell phones and microwave ovens.

Ionizing radiation has the ability to break molecules apart and create charged particles that can travel through matter to reach the surface of objects. These particles can enter living cells and damage genetic material contained within them, leading to mutation and cancer development. Radiation exposure increases the risk of developing cancer later in life. Children, adults older than 40, and people with a history of cancer or leukemia are especially vulnerable to the health effects of radiation. The more radiation you are exposed to, the higher your risk of illness will be.

What happens when radiation destroys your DNA?

When radiation destroys DNA, the body, in most situations, heals the damage. The cell may perish if the damage is too severe and overwhelms typical cellular defenses. When a large number of cells die, the body responds with an inflammatory reaction in which it sweeps away the dead cells and heals the injured tissue. Healthy cells replace the lost cells, and the body returns to normal.

The immune system plays a major role in recovery from radiation injury. During this process, white blood cells work with other cells to destroy any remaining cancer cells. Cancer patients treated with radiation often experience long-term side effects such as fatigue, diarrhea, appetite loss, depression, and infection. These are all part of the body's natural response to injury; however, for many people, these side effects can remain long after treatment has ended.

Radiation therapy is used to treat many types of cancers including breast, prostate, lung, head and neck tumors. It can also be used as adjuvant treatment following surgery to kill any lingering cancer cells or to reduce the risk of recurrence. Radiation therapy uses high-energy rays from X-rays, electrons, protons, or ions to destroy cancer cells without harming healthy tissues. The type of radiation used depends on what area of the body is being treated as well as the size of the tumor.

During radiation therapy, some organs are exposed to high levels of radiation, which can lead to serious health problems.
