How to become a Radiation Therapist


Radiation therapy is used to treat cancer as well as to relieve the symptoms of the disease. Internal and external beam radiation therapies are local treatments that target specific parts of the body to cure, prevent recurrence, and stop or delay cancer cell proliferation. Read on for a guide on how to become a radiation therapist.

Radiopharmaceuticals, brachytherapy, and systemic radiation therapy are examples of internal radiation therapy. Palliative radiation therapy is intended to reduce the intensity of symptoms such discomfort, difficulty breathing, and incontinence. 

Radiation therapists are in charge of a variety of critical tasks. These medical professionals aid in the treatment of cancer and other diseases by administering radiation therapy to patients and explaining it to them; operating x-ray machines and other related medical equipment to ensure they are up to certain standards; monitoring the patient throughout the treatment; and recording the treatment’s results once it is completed.

Radiation therapists may communicate with and report to radiation oncologists, oncology nurses, radiation physicists, and anyone else involved in the process of giving and monitoring radiation treatment because they are most typically part of an oncology team. 

Radiation therapists, in the end, have important roles to play in helping patients improve their quality of life. Patients feel most at ease when they are informed and emotionally cared for, according to a study conducted by the National Center for Biotechnology Information. One of the ways patients gained this crucial emotional comfort throughout treatment was through their relationships with radiation therapists.

Responsibilities and Requirements 

Those interested in a career in radiation treatment should be informed of licensing procedures as well as important role responsibilities. 

To work as a radiation therapist in the United States, an individual must first complete a recognized degree in the discipline of radiation therapy or radiography. This includes meeting the American Registry of Radiologic Technologists’ (ARRT) Radiation Therapy Didactic and Clinical Competency Requirements in an accredited program. 

Many four-year universities and colleges offer degrees that satisfy these requirements while yet allowing students to pursue other interests. As a result, many people choose for inclusive bachelor’s degrees. A radiation therapist, on the other hand, does not need to have a bachelor’s degree in radiation therapy or radiography; instead, persons interested in pursuing a career in radiation therapy can earn an associate’s degree from a recognized institution, which could be a community or technical college. 

The Joint Review Committee on Education in Radiologic Technology (JRCERT) is the only accreditation agency for radiation therapy programs approved by the Council on Higher Education Accreditation and the US Department of Education. 

After earning either an undergraduate or graduate degree in radiation therapy, a person must get certified by the American Registry of Radiologic Technologists (ARRT), the national licensing authority for radiation therapists.

Obtain ARRT certification. 

The ARRT (American Registry of Radiologic Technologists) offers a radiation therapy credential (T). 

Following graduation, an individual can register with ARRT to take an examination, which must be passed in order to become a qualified radiation therapist. Although the exam is only one day long, students must first submit an application and money, as well as prepare for it, which could take months. Candidates have three years from the conclusion of their educational prerequisites to apply for ARRT certification, and they are allowed three attempts at the exam during that time. 

Look for a job or continue your education. 

Finally, individuals with at least an associate degree can work as radiation therapists or, with more extensive training, as dosimetrists, after they are certified. Radiation specialists are used in a variety of settings, including hospitals, cancer clinics, and educational institutions. In order to explore chances in teaching, technical sales, research, or management, therapists may pursue further specialization in a subfield, supporting discipline, or related field, depending on their professional goals. 

Is it Difficult to Work as a Radiation Therapist? 

Radiation therapy, like any other medical profession, may be difficult. However, most of the difficulties may be overcome with education and experience. Let’s go over some of the difficulties you can face as you begin your career. 

Requirements for Education 

Radiation therapy necessitates a unique set of skills. The use of ionizing radiation treatment to your patients will be your primary responsibility. You must understand how to prepare the proper treatment dosage, how to properly position patients, and how to track therapy success. 

Radiation therapy also necessitates a thorough understanding of human anatomy and how the body responds to radiation. The subject matter can be difficult to grasp at first, particularly for those who are new to the medical industry. 

Emotional Stress: As a radiation therapist, you’ll be able to provide emotional support to cancer patients. While this is a gratifying component of the job, it can also be an emotionally draining experience. Emotional stress can be caused by difficult diagnosis and even patient loss. 

You’ll be able to get your first entry-level radiation therapy job after graduation. As you acclimatize to being in the field and working in a new setting, you’ll encounter a learning curve.
