How does radiation affect normal cells?
Because radiation is most harmful to quickly growing cells, radiation therapy damages cancer cells more than normal cells. This prevents the cancer cells from growing and dividing, and leads to cell death. Radiation therapy is used to fight many types of cancer.
How does radiation lead to cancer?
High-energy radiation, such as x-rays, gamma rays, alpha particles, beta particles, and neutrons, can damage DNA and cause cancer. These forms of radiation can be released in accidents at nuclear power plants and when atomic weapons are made, tested, or used.
What is the harm of radiation?
Exposure to very high levels of radiation, such as being close to an atomic blast, can cause acute health effects such as skin burns and acute radiation syndrome (radiation sickness”). It can also result in long-term health effects such as cancer and cardiovascular disease.
Can you get cancer from nuclear radiation?
At high doses, ionizing radiation can cause immediate damage to a person’s body, including radiation sickness and death. Ionizing radiation is also a carcinogen, even at low doses; it causes cancer primarily because it damages DNA.
Is radiation worse than chemo?
Radiation therapy involves giving high doses of radiation beams directly into a tumor. The radiation beams change the DNA makeup of the tumor, causing it to shrink or die. This type of cancer treatment has fewer side effects than chemotherapy since it only targets one area of the body.
Can you get cancer from radiation treatments?
Doctors have known for a long time that radiation can cause cancer. And research has shown that radiation treatment for one cancer can raise the risk for developing a different cancer later. Factors that can affect that risk include the amount of radiation used and the area that was treated.

It might take from 10 days to many months for the immune system to recover completely.
Does radiation lower your immune system?
Radiation therapy can potentially affect your immune system, especially if a significant amount of bone marrow is being irradiated because of its role in creating white blood cells. However, this doesn’t typically suppress the immune system enough to make you more susceptible to infections.
What is the first sign of too much radiation?
The initial signs and symptoms of treatable radiation sickness are usually nausea and vomiting. The amount of time between exposure and when these symptoms develop is a clue to how much radiation a person has absorbed.
