To minimise the risk of radiation exposure and its associated stochastic effects, radiologists and other healthcare professionals follow strict radiation protection guidelines and employ safety measures.
Many IR procedures use X-rays or fluoroscopy, exposing both patient and staff to radiation. Some use very little radiation and more for complex procedures.
Most of the man-made radiation we are exposed to comes from the medical procedures we undergo—standard X-ray and CT scans to diagnose injuries and disease. Radiation is also used in radiation therapy to improve health and even save lives.
The trefoil – a three-bladed radiation warning symbol – wasn’t originally black and yellow. In 1948 it was considered for wider use but its first print was a magenta symbol on a blue background.
Aside from Marie Curie, many other women pursued a career in science and contributed to our modern understanding of radiation. Let’s take a look at their profiles.
To measure radiation activity or the amount of radiation coming out of a source, Australians use the unit Becquerel (Bq) from the international system (SI) of units or the metric system.
Did you know that X-rays were discovered by accident? It all began with physicist Wilhelm Conrad Röntgen on November 8, 1895.
All careers that work with and around radiation sources are very careful. There are regulations on dose limits and radiation workers strictly follow them.
As the field of medical imaging advances and expands, the risk of radiation exposure of healthcare workers and patients is something that we cannot simply understate.
