Millimeter-wave scanners use radio waves and produce no ionizing radiation. When we talk about radiation, we're usually referring to ionizing radiation, which has the energy and other properties capable of damaging DNA and leading to cancer. In very high doses, ionizing radiation can cause burns and even kill.

X-ray machines contain no radioactive material, and thus pose no threat of contamination even when energized. When energized, an x-ray machine is a source of external radiation exposure.

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.

The technology that is used in airport security scanners has the potential to be a skin cancer diagnostic tool, a scientist is claiming. The scanners use so-called terahertz radiation ("t-rays"), which has the ability to look through human skin and tissue. T-rays are considered non-ionizing, similar to visible light.

X-Rays are also used in airport security checks, to see inside your luggage. They are also used by astronomers - many objects in the universe emit X-rays, which we can detect using suitable radio telescopes. Lower energy X-Rays don't pass through tissues as easily, and can be used to scan soft areas such as the brain.

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 imaging involves the use of x-rays, which are a form of ionizing radiation. Exposure to ionizing radiation is known to increase the risk of cancer. Standard x-ray procedures, such as routine chest x-rays and mammography, use relatively low levels of ionizing radiation.

Chest X-rays can detect cancer, infection or air collecting in the space around a lung, which can cause the lung to collapse. They can also show chronic lung conditions, such as emphysema or cystic fibrosis, as well as complications related to these conditions.

Radiology Technicians Do people who work with X-rays every day have lifetime occupational cancer risks? Radiology technicians who were working before 1950 have an increased cancer risk, specifically for blood cancers, breast cancers, thyroid cancers, and skin cancers, according to the National Cancer Institute.

Airport body scanners are safe during pregnancy, here's how they work. ... Airport scanners in the US come in two types: millimeter-wave scanners and x-ray backscatter scanners. Both types of scanners are safe to use on children, adults, or women who are pregnant.

"The X-ray machines emit a low radiation that has not consistently shown to affect medications. If it did, most likely the medication would have a warning on its medication label," he says.

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.

Risks. In general, chest X-rays are very safe. Although any exposure to radiation poses some risk to the body, the amount used in a chest X-ray is small and not considered dangerous. It's important to know that radiologists use the minimum amount of radiation required to get the best results.

April 10, 2012 -- Getting frequent dental X-rays appears to increase the risk for a commonly diagnosed brain tumor, a new study finds. Exposure to ionizing radiation -- the kind found in X-rays -- is the biggest known environmental risk factor for largely non-malignant meningioma brain tumors.
