Radiation Therapist Jobs in Illinois: Frequently Asked Questions
How do you become a radiation therapist in Illinois?
To work as a radiation therapist in Illinois, you must hold an active license issued by the Illinois Department of Financial and Professional Regulation. Licensure requires completing an accredited radiation therapy program and passing the American Registry of Radiologic Technologists exam in Radiation Therapy. Illinois does not offer reciprocity in the traditional sense, but ARRT-certified therapists from other states can apply for an Illinois license by endorsement through IDFPR.
How much do radiation therapists make in Illinois?

Which companies hire radiation therapists in Illinois?

Illinois's large integrated health systems and academic medical centers tend to post the most consistent volume, particularly those with dedicated oncology institutes and research programs.
Which Illinois cities have the most radiation therapist jobs?
Rockford, Glenview, and Alton have the most radiation therapist openings in Illinois. Chicago dominates because of its concentration of major academic medical centers and comprehensive cancer programs, while Springfield and Peoria reflect steady regional hospital demand anchored by systems like HSHS Medical Group and OSF HealthCare serving central Illinois populations.
Are there remote radiation therapist jobs in Illinois?
Yes, but they're rare. Radiation therapy is a hands-on clinical role requiring direct patient contact and operation of specialized equipment, so remote work is not a realistic option for most positions. About 0% of radiation therapist openings tied to Illinois are remote or hybrid as of October 2026, and those roles are typically in treatment planning, dosimetry support, or clinical education rather than direct patient care.
How can I get hired as a radiation therapist in Illinois with little or no experience?
The most realistic entry path is applying to new-graduate positions at large Illinois health systems that regularly onboard entry-level therapists, such as Northwestern Medicine and Rush University Medical Center, which run structured orientation programs for graduates pending ARRT certification. Candidates who completed clinical rotations at Illinois facilities have a clear advantage. Lateral experience as a radiologic technologist or radiation therapy assistant can also open doors, and holding your IDFPR license application complete before applying signals readiness to Illinois hiring managers.
