1 Chest X Ray Radiation

Posted onby admin

The exact amount of radiation exposure in an x-ray procedure varies depending on the part of the body receiving the x-ray. Some examples of common x-ray procedures and approximate exposures are:

X-ray skull / X-ray chest / X-ray thoracic spine / Mammogram / CT head or neck 0.001-0.01 1 in 1,000,000 CT pulmonary angiogram / Lung ventilation scan 0.01-0.1 1 in 1,000,000 to 1 in 100,000 X-ray abdomen / pelvis / hip or barium meal / CT chest and upper abdomen Nuclear medicine scans using Technetium-99m including thyroid, lung perfusion. Chest X-ray: Equivalent to 2.4 days of natural background radiation; Skull X-ray: Equivalent to 12 days of natural background radiation; Lumbar spine: Equivalent to 182 days of natural background.

  1. Not exactly: The exposure from the average chest xray is 0.1msv (milliserverts). The mammogram is 0.4 msv. A ct of the chest is 7 msv. The risk for the chest xray.
  2. Radiation exposure during a single chest X-ray (0.014 mSv) is equivalent to 3 days of natural radiation. An abdomen X-ray (0.7 mSv) is equivalent to 4 months of natural background radiation. A CT head scan (2 mSv) is equal to 1 year of natural radiation exposure 2.

Is Chest X Ray Radiation Dangerous

Generally, the radiation received during an x-ray is small compared to other radiation sources (e.g., radon in the home). The average annual radiation dose from natural background sources (for comparison) is 3.0 mSv (300 mrem). For more information on radiation sources, see the Radiation Sources and Doses webpage or calculate your radiation dose.

Learn about Radiation Terms and Units like mSv and mrem, which are used to measure radiation dose.
