There is no universal answer to this question as licensure for radiologic technologists (RTs) varies from country to country. In the United States, RTs must obtain a license in order to practice, but the requirements for licensure may be different in other countries. It is important to research the requirements for RT licensure in the country where you wish to practice. Some countries may not require a license, while others may have different educational and/or experience requirements.
In general, licensure is meant to protect the public by ensuring that only those who have met certain standards are allowed to practice in a particular profession. licensure is also meant to ensure that practitioners are kept up-to-date on new developments in their field and that they adhere to ethical standards. Therefore, it is likely that having a license would be seen as a positive attribute by employers in any country, though the specifics may vary.
