Information about X-Rays and Radiation Dose
X-Rays involve the use of ionising radiation.
Ionising radiation may cause damage to the body’s cells. To ensure any radiation dose and the potential risk it may represent remains very small, both your referring doctor and our technical staff assesses your need for the examination and the diagnostic benefits against the potential risk before referring and conducting the procedure. No radiation remains in your body after the test.
While patients may receive a radiation dose from a medical imaging procedure, radiation is found all around us all the time – in the soil, the air, plants, buildings etc. This is called background radiation. While dosage from medical imaging varies too, it still represents only a very small fraction of our lifetime exposure to background radiation.
Extra consideration is made for imaging of women of reproductive age and children. Medical imaging for these groups may still be needed and may indeed be very important, but extra care must be taken to optimise the study and ensure the benefit outweighs any potential risks.
If you know you are or think you may be pregnant, you must advise your referring doctor and the person performing the x-ray examination, who can discuss the risks and benefits associated with the particular procedure.
