Radiation and electrons bombarded by radiation move haphazardly inside the cell, resulting in damage to the various molecules forming the cell. Chromosomal DNA inside the cell nucleus can also be damaged.
How does radiation affect the tissue?
High doses tend to kill cells, while low doses tend to damage or change them. High doses can kill so many cells that tissues and organs are damaged. This in turn may cause a rapid whole body response often called the Acute Radiation Syndrome (ARS).
How does radiation affect our cells?
Ionizing radiation can affect the atoms in living things, so it poses a health risk by damaging tissue and DNA in genes. has sufficient energy to affect the atoms in living cells and thereby damage their genetic material (DNA). Fortunately, the cells in our bodies are extremely efficient at repairing this damage.
What are the 3 ways radiation can affect a cell?
How does ionizing radiation affect cells?
- The radiation could pass through the cell without damaging the DNA.
- The radiation could damage the cell's DNA, but the DNA repairs itself.
- The radiation could prevent the DNA from replicating correctly.
- The radiation could damage the DNA so badly that the cell dies.

Can radiation cause tissue damage?
Radiation, while effective in the treatment of cancerous tumor cells, is not selective in the tissue it targets. In other words, while effectively destroying cancerous tumor cells, radiation can also cause damage to healthy tissue. This damage can occur anywhere between two weeks to 20 years after treatment.
How does radiation affect mitosis?
Radiation in sufficient doses can inhibit mitosis, that is, the cell's ability to divide and proliferate indefinitely. The inhibition of cellular proliferation is the mechanism by which radiation kills most mammalian cells.
What is a radiation induced tissue reaction?
Radiation injury due to large and very large doses is referred to as a tissue reaction. The dose needed to cause visible tissue injury varies with tissue type. Ionizing radiation can increase the risk of cancer. Radiation exposure of sperm and egg cells carries little increased risk of genetic defects in offspring.
Why does radiation affect the body?
How Radiation Affects Your Body. Radiation can damage the DNA in our cells. High doses of radiation can cause Acute Radiation Syndrome (ARS) or Cutaneous Radiation Injuries (CRI). High doses of radiation could also lead to cancer later in life.
How does alpha radiation damage cells?
Inside the body, however, they can be very harmful. If alpha-emitters are inhaled, swallowed, or get into the body through a cut, the alpha particles can damage sensitive living tissue. The way these large, heavy particles cause damage makes them more dangerous than other types of radiation.
Does radiation shrink tissue?
Whether you receive radiation therapy before or after surgery depends on the size and location of the tumor. Before surgery, radiation can shrink a tumor. This makes it easier for the surgeon to remove it without harming surrounding tissue and organs.
