Medical Dosimetry - Certificate

Program Brochure (PDF)

The Medical Dosimetry program is designed to train personnel in the discipline of dosimetry within a radiation oncology environment, and to prepare them to take the Certified Medical Dosimetrists board examination.

Mission Statement

The mission of the Medical Dosimetry Certificate Program is to prepare professionals in the field of Medical Dosimetry with students receiving broad education and training in all aspects of the profession.  This will include critical thinking, clinical competence, effective communication, and professionalism as they apply to the field of Medical Dosimetry.  The program encourages intellectual, physical, social, and spiritual development by emphasizing these goals in its curriculum, which are reflected in the mission statements of the School of Allied Health Professions, Loma Linda University, and Loma Linda University Medical Center - “To Make Man Whole”.

Medical dosimetry is a very dynamic, exciting field involving a combined knowledge of mathematics, physics, and the biologicial and medical sciences. Dosimetrists plan optimal isodose distributions and treatment dose calculations for a variety of external beam, as well as brachytherapy treatments.

Medical dosimetrists must have excellent analytical skills, an ability to critically evaluate data, and an aptitude for physics and mathematics. They must also be able to work closely as a team with physicists, physicians, radiation therapists, and other hospital personnel.

A shortage of training programs exist in the field, which causes a shortage of dosimetrists. This program will aim to provide a supply of well-trained dosimetrists who will be able to meet the needs of radiation oncology facilities in the local area and beyond.

Program Information

The medical dosimetry program is a full time (40 hour per week) 15-month long program that prepares the student to be board eligible for the CMD (Certificate in Medical Dosimetry) Examination.  The program is competitive as only two students can be admitted every year.  The curriculum varies depending upon a student's entrance track, and is very demanding both didactically and clinically.  It is recommended that students study for at least two hours per day outside of set program hours, to ensure success in the program.

Clinical Training

The program ensures that the students are trained in all aspects of treatment planning with the various modalities available in the field.   The majority of the clinical work is conducted within the Radiation Medicine department at Loma Linda University Medical Center, but students also spend six week blocks of time at Long Beach Memorial Medical Center and City of Hope Medical Center to expose them to different treatment machines, software systems, and treatment techniques.

Essential Job Functions

The essential job function of a medical dosimetrist requires certain physical, cognitive, and emotional attributes.  Although contact with patient is often minimal it is still ncessary to be able to physically assist as needed.  Prolonged sitting, keyboard and mouse manipulation skills are necessary.  Visual acuity at a distance of approximately 15 inches is essential as is the ability to view a computer screen for hours at a time.  Candidates must have good coordination and fine motor skills in order to manipulate brachytherapy sources, and construct beam modifying devices.  The ability to think critically, integrate data, and comprehend theoretical constructs is essential. 

Dosimetrists work under physician's direction to build three dimensional, virtual models of patient anatomy and isodose curve distributions, and it is necessary to be able to oversee the translation of such models into clinical practice.

Excellent communication skills are essential as dosimetrists have to interact with physicians, physicists, radiation therapists, and other professionals to ensure that treatment plans are accurately constructed and delivered.  For major duties and job skills refer to the AAMD Website.

Program Accreditation

The certificate in Medical Dosimetry is accredited by: WASC (Western Association of Schools and Colleges) JRCERT (Joint Review Committee on Education in Radiologic Technology.  Contact Information:  20 North Wacker Drive Suite 2850, Chicago IL 60606-3182.  Phone (312) 704-5300(312) 704-5300   Fax (312) 704-5304  Website  www.jrcert.org  Email   mail@jrcert.org

Term Dates

The Medical Dosimetry Certificate Program follows the Loma Linda University quarterly academic terms.  The program begins each September.  The Fall quarter runs from the end of September to mid-December.  The Winter quarter runs from the first part of January to mid-March.  The Spring quarter runs from the end of March to middle of June.  The summer quarter runs from the end of June to the beginning of September.  Please refer to the Academic Calendar since the actual dates change annually.

Program Prerequisites

Students will either need to have:

AART registration in Radiation Therapy Technology with a minimum of two years post graduation clinical experience and a Bachelor's degree in any topic.  Additional prerequisites:  College Algebra, Trigonometry


A Bachelor's degree in Physics or Mathematics from an accredited university. Additional prerequisites:  Anatomy and Physiology (no lab needed), Medical Terminology

All course requirements must be met before the start of the program. 

Program Objectives

Upon completion of the program, the student should be qualified to:

  • Demonstrate an ability to accurately complete dosimetric calculations and procedures as they pertain to all aspects of treatment planning for external beam and brachytherapy techniques.
  • Develop and refine critical thinking skills to enhance the ability to analyze and compute dosimetric data as it relates to all aspects of radiation therapy treatment.
  • Exhibit professional behavior that includes the ability to communicate with other professionals and work well individually and as a member of a team.
  • Manage patients in an empathetic manner and exhibit basic patient care proficiencies.
  • Support the professional code of ethics and comply within the scope of practice.


During the 15-month Certificate Program in Medical Dosimetry, students take formal classes along with instruction in a clinical setting.  This includes participation, under closer supervision, in the actual procedures within the Radiation Physics/Dosimetry Department.

This is a full time, 40-hour per week program.  The schedule is coordinated with participating clinical affiliates and clinical hours are arranged around lectures.

The curriculum differs depending on the entry track.
