X-ray technicians are trained medical professionals that work in hospitals, medical centers and other institutions operating x-ray machinery to take internal pictures of the human body. This article will go over what an x-ray technician does, the educational requirements for becoming an x-ray technician, job prospects for the field, and the long-term effects of being exposed to radiation on a daily basis in this occupation.
Identification
X-ray technicians, also known as radiologic technologists or radiographers, take x-ray films of the body to help doctors diagnose diseases, illnesses and injuries and conditions that can only be diagnosed by seeing the body internally. They are trained to manipulate x-ray equipment, and educated in human anatomy, physiology and pathology. Some x-ray technicians choose to specialize in CT scans (computed tomography), MRI (magnetic resonance imaging) or mammography.
Function
An x-ray technician's primary job is to take x-ray films while keeping the patient safe and as comfortable as possible. This includes proper positioning of the patient to take the appropriate pictures, as well as positioning the equipment at the correct angles and using the necessary protective shields against radiation. Once the films have been taken, the x-ray technician is then responsible for checking that the film was taken properly and then developing it. In addition to taking x-rays, technicians must also keep records, communicate with doctors and maintain the equipment.
Time Frame
Programs in radiologic technology range from one to four years and are offered in hospitals, colleges/universities and vocational schools. Students may obtain a certificate or an associate or bachelor's degree, depending on the level and length of training they pursue. Upon graduation from a radiologic technology program, certification is available through the American Registry of Radiologic Technologists (ARRT), and many states use these exams for state licensing. Once certified, radiologists must maintain at least 24 hours of continuing education every two years.
Potential
Job outlook for x-ray technicians is favorable, and employment is expected to grow faster than average. As the population grows and becomes older, the demand for medical services such as imaging will continue to rise and job opportunities will increase. New jobs will also appear in places other than hospitals, such as physician's offices and imaging centers, due to these facilities growing and offering more outpatient services. Technologists willing to specialize in CT, MRI or mammography and those that are willing to relocate will have increased and more favorable employment opportunities.
Effects
There is a risk associated with being an x-ray technician, due to the exposure to radiation on a daily basis; however, this risk has been minimized with the use of lead aprons, gloves and instruments that measure radiation levels. The x-ray technician wears a badge that measures the amount of radiation they have been exposed to and detailed records are kept in order to avoid overexposure. There is a certain cumulative lifetime dose that should not be exceeded, and by keeping a close eye on daily levels, overexposure is not a great concern.
