What does the term “dual licensing” refer to?

The term "dual licensing" specifically refers to holding separate licenses for multiple categories of radiologic technology. This means that an individual possesses distinct licenses that allow them to practice in more than one specialized area within the field of radiology, such as mammography, MRI, or radiation therapy, each requiring its own set of qualifications and training. This ability to hold multiple licenses enhances a technologist's versatility and capability to work across various radiologic departments or specialties, making them more valuable in clinical settings.

The other options provided describe different aspects of licensing and certification but do not accurately capture the essence of dual licensing. For instance, holding a license for both diagnostic and therapeutic procedures could describe a broad practice scope rather than the specific dual licensing terminology. Operating independently usually pertains to different qualifications related to practice authority rather than the concept of dual licensing. Lastly, certification for both national and state standards is related to compliance and credentialing rather than the concept of holding multiple licenses for various categories of practice.
