what are the risks of x ray exposure?

While X-rays are linked to a slightly increased risk of cancer, there is an extremely low risk of short-term side effects. Exposure to high radiation levels can have a range of effects, such as vomiting, bleeding, fainting, hair loss, and the loss of skin and hair.

While traditional X-rays are considered safe, digital X-rays produce 80% less radiation than traditional. This means it is highly unlikely you would develop issues from occasional traditional radiation exposure, but it is even less likely with the process used in digital X-rays.

Radiation does have some risks to consider, but it is also important to remember X-rays can help detect disease or injury at early stages so the ailment can be treated appropriately. Sometimes X-ray testing can be life-saving. The risk from X-rays comes from the radiation they produce, which can harm living tissues.

CT scans expose you to radiation. A CT scan uses X-rays to create images of the brain and skull. X-rays are a form of radiation which increases the risk of cancer over your lifetime. Risks from radiation exposure add up, so it is best to avoid unnecessary radiation when possible.

However, the very properties that make them useful for seeing inside the body, are also what make them harmful. As they pass through us, X-rays can damage some of our cells, by causing changes in our DNA that have been linked to an increased risk of cancer.

However, CT scans use x-rays, and all x-rays produce ionizing radiation. Ionizing radiation has the potential to cause biological effects in living tissue.

Chest CT scans have some risks. In rare instances, some people have an allergic reaction to the contrast dye. There is a slight risk of cancer, particularly in growing children, because the test uses radiation.

What are the risks of an MRI? Because radiation is not used, there is no risk of exposure to ionizing radiation during an MRI exam. Due to the use of the strong magnet, special precautions must be taken to perform an MRI on patients with certain implanted devices such as pacemakers or cochlear implants.

How X-rays work. X-rays are a type of radiation that can pass through the body. They can't be seen by the naked eye and you can't feel them. As they pass through the body, the energy from X-rays is absorbed at different rates by different parts of the body.

Large doses of radiation can cause harmful effects like nausea and vomiting. Small doses of radiation from more common everyday activities cannot. Radiation doses from diagnostic medical exams like dental x rays will not cause headaches or otherwise make you sick.

Some people worry that X-rays aren't safe because radiation exposure can cause cell mutations that may lead to cancer. The amount of radiation you're exposed to during an X-ray depends on the tissue or organ being examined.

['The average radiation exposure per x-ray is . 28 mSv. You would need approximately 36 x-rays throughout your lifetime to raise your risk of cancer by . 05%.', 'The average radiation exposure per CT scan is 6.3 mSv. After approximately two CT scans, your risk of cancer increases by . 05%.']

In the case of standard procedures, there is no or negligible chance of risk. It will not matter to you if you are going through ten x-rays in a year or two x-rays in a year.

Side effects Exposure to high radiation levels can have a range of effects, such as vomiting, bleeding, fainting, hair loss, and the loss of skin and hair. However, X-rays provide such a low dose of radiation that they are not believed to cause any immediate health problems.

CT scans are quick, painless and generally safe. But there's a small risk you could have an allergic reaction to the contrast dye used and you'll be exposed to X-ray radiation. The amount of radiation you're exposed to during a CT scan varies, depending on how much of your body is scanned.

Ask both dentists to help you with forwarding your X-rays. Dental X-ray exams are safe; however, they do require very low levels of radiation exposure, which makes the risk of potentially harmful effects very small.
