JRCERT

Joint Review Committee on Education in Radiologic Technology

The official accrediting agency for radiation therapy educational programs in the United States.

Role in radiation therapy: Accredits radiation therapy programs so graduates are eligible for ARRT certification. Program quality, curriculum, and clinical competency standards all trace back to JRCERT accreditation.

ACR

American College of Radiology

A national professional organization of radiologists, radiation oncologists, and medical physicists.

Role in radiation therapy: Sets practice standards and accreditation for imaging and radiation oncology facilities, and publishes evidence-based Appropriateness Criteria that guide appropriate use of imaging and therapy.

AMA

American Medical Association

The national organization representing physicians in the United States.

Role in radiation therapy: Maintains the CPT code set used to bill radiation therapy treatments — the codes therapists, dosimetrists, and billing staff rely on for simulation, treatment delivery, and management services.

ARRT

American Registry of Radiologic Technologists

The national credentialing organization for radiologic technologists, including radiation therapists.

Role in radiation therapy: Administers the certification exam every radiation therapy student must pass, sets continuing education and ethics requirements, and maintains the registered technologist (R.T.) credential used for employment and licensure.

ASRT

American Society of Radiologic Technologists

The professional membership society for radiologic technologists and radiation therapists.

Role in radiation therapy: Provides continuing education materials, publishes practice standards, and advocates for the profession at the state and federal level — the professional home base for working therapists.

FDA

Food and Drug Administration

The federal agency that regulates medical devices and radiation-emitting products.

Role in radiation therapy: Reviews and clears treatment machines such as linear accelerators before they reach clinics, and enforces performance and safety standards for radiation-emitting electronic products.

NCCN

National Comprehensive Cancer Network

An alliance of leading cancer centers that publishes clinical practice guidelines.

Role in radiation therapy: Its evidence-based guidelines define standard-of-care cancer treatment, including when and how radiation therapy is used for each disease site — the backbone of treatment protocols students learn.

ACRO

American College of Radiation Oncology

A professional society dedicated specifically to the practice of radiation oncology.

Role in radiation therapy: Accredits radiation oncology practices through peer review and provides quality benchmarks, practice surveys, and coding guidance that help departments deliver safe, consistent care.

WHO

World Health Organization

The United Nations agency directing international public health.

Role in radiation therapy: Publishes global radiation safety guidance with the IAEA and works to expand safe access to radiotherapy worldwide; its international standards complement the US rules this app teaches.

NRC

Nuclear Regulatory Commission

The federal agency that licenses and regulates radioactive materials.

Role in radiation therapy: Governs the medical use of byproduct material — brachytherapy sources, sealed isotopes, and gamma knife units — under 10 CFR Part 35, including training, dosimetry, and event reporting requirements.

NCRP

National Council on Radiation Protection and Measurements

A nonprofit chartered by Congress to advise on radiation protection.

Role in radiation therapy: Publishes the dose-limit recommendations that shape US radiation safety practice — the occupational and public exposure limits that radiation safety programs are built around.
