What is a radiation therapist and what do they do?

A radiation therapist is going to be a health professional that works in the field of radiation oncology.

Radiation oncology is using radiation within the treatment of cancer.

You will work with radiologists to implement different treatment plans for patients.

Normally they specialize in using high doses of radiation to treat cancerous growths.

They focus on trying to shrink and remove the tumors in general and not all tumors are cancerous.

The radiation therapist is in charge of operating the machines that deliver radiation therapy.

A radiation therapist will also use a stimulator and possibly a CT scanner. They use these to gather the needed information and data for the patient. With that information, a doctor will plan each patient’s particular radiation treatment.

How do you become a radiation therapist?

There is no on the job training to become a radiation therapist.

You can complete a program that leads to an associate degree or a bachelor’s degree in radiation therapy. 

Typical entry-level education only requires an associate degree. However, having a bachelor’s degree could help you gain a higher salary.

As a radiation therapist, you are going to be required to be licensed or certified in most states.

There is a chance you may have to pass some sort of national certification exam.

This means that you should look for the schools in your area that have the best radiation programs.

Some schools don’t offer this program, so it is also important to make sure that they have that major where you want to go to college.

This career is a great because you can go to school for 2-years and then start working.

What classes do you need to take to become a radiation therapist?

Some of the classes that you can take depend on what school you were going to. They will tell you the prerequisite and general courses they require.

However, during your actual radiation therapy classes, you’ll be taking a lot of classes about procedures and the scientific theories behind them.

Often, the programs will give you experience in actual clinical settings as well.

Other classes that you might have to take include:

  • Physiology
  • Anatomy
  • Algebra
  • Physics
  • Computer science
  • Research methodology

There’s not much math involved in this major. This will be good for you if you are interested in the medical field but you’re not good at math.

There is a lot of science involved so make sure that you are interested in taking 1 to 2 years of science classes.

It is important to get all the information about what you’re going to be studying in the major.

Even though the actual experience and job can be a lot different than the classes that you take.

You need to be interested in radiation therapy so make sure you like the subject.

The minimum requirement to be a radiation therapist is an associate degree which is a two-year program.

So you can get a job as a radiation therapist after only two years of school.

However, many people will tend to get a bachelors instead.

If you have any ideas about where you want to work in the future. It would be useful for you to look up the requirements of the states and companies.

Some employers will require a four-year bachelor’s degree in order to become a radiation therapist.

If they are a very well-known hospital or workplace then they may be looking for students with a 4-year degree.

If you do end up getting your bachelors, you’ll also get to take classes like:

  • Apply radiation therapy

However, in general, the requirements normally include some sort of graduation from an accredited radiation therapy program.

You need to get ARRT certified.

The ARRT certification means that the student who completed an accredited radiation therapy program adheres to ethical standards and passes the certification exam.

The exam measures your knowledge that an entry-level radiation therapist should know about the daily tasks and technology.

The tests are known to be slightly challenging, yet fair.

The tests are created from experts around the country including registered technologists in the discipline that you’re interested in.

If you fail this exam three times in three years you will have to try again for eligibility to apply for certification.

The testing scores range from 1 to 99 and a score of 75 is needed to pass in general.

These are the types of things that you can look into if you are concerned about your overall salary.

The average salary of a radiation therapist is somewhere around $80,000 per year. You will typically start at about $55,000 per year and you go up from there.

The states that are the best paying include California, New Jersey, Oregon, Connecticut, and Washington.

Because of this radiation therapy classes are not normally available in a fully online form.

Radiation therapy is still not available at some schools. It is unlikely that you will find very many places where a hybrid or online version is available.

Your best bet is to try to get as many online classes as you can or look for hybrid versions.
