Radiation Therapist Jobs in Colorado: Frequently Asked Questions

How do you become a radiation therapist in Colorado?

To work as a radiation therapist in Colorado, you must hold a license issued by the Colorado Department of Public Health and Environment under its radiation control program, and you must pass the ARRT Radiation Therapy certification exam. Colorado requires completion of an accredited radiation therapy program, typically an associate or bachelor's degree from a JRCERT-accredited institution. After passing the ARRT exam, you apply for a Colorado radiation therapist license before practicing independently.

How much do radiation therapists make in Colorado?

Radiation therapists in Colorado earn a median of about $108,020 a year, based on May 2025 Bureau of Labor Statistics wage data, ranging from around $90,970 for the lowest 10% to over $130,750 for the top 10%. Pay rises with experience, specialty, and employer.

Which companies hire radiation therapists in Colorado?

Employers hiring radiation therapists in Colorado right now include UCHealth, Vail Health, and Banner Health, based on current listings on Migrate Mate as of August 2026. Colorado's dominant integrated health systems tend to post the most consistently across multiple facilities, so watching openings at large regional networks gives you the broadest view of available positions.

Which Colorado cities have the most radiation therapist jobs?

The cities with the most radiation therapist openings in Colorado are Edwards, Englewood, and Fort Collins. Denver and the surrounding metro drive the largest share of openings because it hosts the highest concentration of major cancer centers and hospital campuses, while Colorado Springs draws volume from its own growing network of regional oncology and outpatient treatment facilities serving southern Colorado.

Are there remote radiation therapist jobs in Colorado?

Yes, but they're rare. About 14% of radiation therapist openings tied to Colorado are remote or hybrid as of August 2026, which is expected given that the core work requires hands-on patient positioning and direct operation of treatment equipment on-site. The portions of the role most suited to remote work are treatment planning review, dosimetry consultation, and certain administrative or quality assurance tasks.

How can I get hired as a radiation therapist in Colorado with little or no experience?

The most realistic entry path is applying for new-graduate positions at Colorado's large health systems, which regularly bring on therapists who have completed their JRCERT-accredited clinical rotations but have not yet accumulated independent work history. UCHealth and Centura Health have historically offered structured onboarding for new graduates, and community cancer centers affiliated with larger networks often have more flexibility with experience requirements than flagship hospital sites. Holding your ARRT certification and an active Colorado license before applying is the single biggest competitive advantage for candidates without prior employment history.

Where can I find and apply to radiation therapist jobs in Colorado?

You can find and apply to radiation therapist jobs in Colorado on Migrate Mate, which lists current Colorado openings across hospital systems, cancer centers, and outpatient clinics. Search the listings, identify the roles that fit your credentials and experience level, and apply directly to the ones that match.
