When it comes to the scattered radiation from a CT scan, it is important to note that the amount of scattered radiation decreases rapidly with distance and is typically highest near the patient being scanned. The specific amount of scattered radiation you may have been exposed to in the scenario you described would depend on various factors, including the distance from the patient, the type of CT scanner used, and the specific scanning parameters employed.
CT scans use X-rays to create detailed images of the body. During the scan, the X-ray beam is directed towards the patient, and some of the X-rays are absorbed by the body tissues, while others are scattered in different directions. The scattered radiation is less focused and can potentially reach areas outside the primary beam path, including the surrounding environment.
To minimize radiation exposure to individuals outside the scanning area, CT scan rooms are designed with shielding materials, such as lead, which can help contain and attenuate the scattered radiation. Additionally, strict safety protocols and guidelines are typically followed to ensure that radiation exposure to patients and medical staff is kept as low as reasonably achievable.
If you have concerns about your specific exposure to scattered radiation during a CT scan, it would be best to consult with a medical professional who can provide accurate and personalized information based on your situation. They will have access to your medical records, knowledge of the specific equipment and procedures used, and can address any specific concerns you may have.
