Investigate a two-year associate degree or four-year bachelor degree programs in radiation dosimetry. Note that bachelor degree programs include more extensive general education requirements than associate degree programs, but both can prepare you for the field. Make sure your program is accredited by the Joint Review Committee on Education in Radiologic Technology, as this will guarantee you the opportunity to become certified in this industry.
Apply to the radiation dosimetrist program of your choice. Complete the school's admissions application, and submit transcripts of all previous college work. Note that schools including Bellevue College in Washington require you to complete courses in English, algebra, human anatomy/physiology, social sciences and humanities before applying.
In addition, be prepared to submit a list of references or recommendation letters. Also, write a personal statement or even complete a personal interview at schools such as the University of Arkansas for Medical Sciences. If requested, complete a professional observation of a practicing radiation dosimetrist as part of the admissions process.
Take classes in radiation treatment planning, physics for medical dosimetry, dosimetry of electron beam therapy and clinical education. Study the biology of cancer, cross-sectional anatomy for radiation dosimetry, health care law, medical terminology and patient care as well.
Complete a practicum/internship in radiation dosimetry, which will give you hands-on experience in this field. Continue to get 24 to 36 months of clinical experience after you finish your academic program so that you can apply for certification to the Medical Dosimetrist Certification Board to become certified in this industry. Voluntary certification -- which involves taking an exam, participating in an interview and being observed by a senior medical dosimetrist -- can make you more marketable to employers.
Consider completing a one-year advanced certificate program or two-year master's degree program in radiation dosimetry to further your education and expand your employment opportunities.
