X-ray Safety: Facts vs Myths About Radiation Exposure
What is X-ray Radiation?
Why is Understanding X-ray Safety Important?
Informed Decision-Making:
Patients who understand the actual risks can make better decisions about their healthcare without unnecessary fear.
Appropriate Use:
Knowledge of X-ray safety helps ensure that these tests are used appropriately, weighing benefits against minimal risks.
Peace of Mind:
Having accurate information helps alleviate anxiety that many patients experience when referred for X-ray procedures.
Best Practices For X-ray Safety
Best Practice #1:
Understanding Actual Radiation Exposure Levels
The radiation dose from a standard X-ray examination is remarkably low in comparison to natural background radiation we’re exposed to daily.
For example, a chest X-ray delivers approximately the same amount of radiation as three days of natural background radiation from the environment. The South African Radiation Protection Association confirms that a single chest X-ray exposes a patient to about 0.1 millisieverts (mSv) of radiation, while we receive about 2-3 mSv annually from natural sources.
It’s important to avoid using outdated terms like “roentgenograms” when describing X-rays, instead using clear, accessible language that patients can understand.
Best Practice #2:
Implementing Appropriate Protective Measures
Proper protection measures significantly reduce unnecessary radiation exposure during X-ray procedures.
At Open Diagnostics centres across South Africa, Radiographers follow strict protocols including using lead aprons for patients when appropriate, collimating the X-ray beam to the area of interest only, and regularly performing quality control tests on equipment to ensure optimal performance with minimal radiation.
When discussing the removal of metal objects before an X-ray, healthcare providers should focus on clothing items with metal components like zippers, buttons, and underwire bras, rather than emphasising jewellery.
Best Practice #3:
Special Considerations for Vulnerable Populations
Certain groups require special attention when it comes to X-ray safety, with protocols tailored to their specific needs.
For pregnant women, Open Diagnostics consider alternative diagnostic methods where possible (ultrasound). X-rays are only performed when absolutely necessary as per referring doctor’s input and follows the principle of “ALARA” (As Low As Reasonably Achievable), taking only one x-ray and using abdominal shielding. X-rays are a contraindication in the 1st trimester. All females of childbearing age are asked about possible pregnancy before any X-ray procedure.
It’s essential to always include a reminder about informing healthcare providers of possible pregnancy before an X-ray, and to communicate with the Radiographer during the procedure about any concerns.

CONCLUSION
X-ray procedures are safe, non-invasive diagnostic tools when used appropriately. The minimal radiation exposure from standard X-ray tests poses negligible risk to patients, with benefits far outweighing potential concerns. By understanding the facts about X-ray safety, patients can approach these important diagnostic tests with confidence rather than fear.
Remember that modern X-ray equipment is designed to minimise radiation exposure, and Radiographers are trained to follow strict safety protocols to ensure patient safety while obtaining the necessary diagnostic information.
