RADIATION THERAPY CORE EXAM SET 2026/2027
QUESTIONS AND SOLUTIONS RATED A+
✔✔Orthogonal: - ✔✔when a beam is perpendicular to another beam; 90 degrees apart
from each other.
✔✔BEV: - ✔✔Beam's Eye View - imaging technique used for quality assurance and
planning of radiation to help prevent error. This is the view of the patient from the
radiation source along the axis of the beam
✔✔Elapsed days: - ✔✔the amount of days from the start to the end of therapy.
✔✔SSD: - ✔✔Source to Surface/Skin Distance - this is the distance between the
radiation source and the skin of the patient.
✔✔SAD: - ✔✔Source to Axis Distance - this is the distance between the radiation
source and the isocenter of the linac.
✔✔Dmax: - ✔✔this is the depth under the skin at which the radiation is at maximum
energy. The dose at this
location is defined to be 100%.
✔✔Linear Accelerator: - ✔✔the machine that generates and guides the radiation to treat
the patient.
✔✔What is Radiation Therapy? - ✔✔the practice of treating cancer patients using a
machine called a linear accelerator
✔✔What Does a Radiation Therapist Do Anyway?! - ✔✔Learn new and specialized
technology that is being used in the fight against cancer. Such as:
IORT (intra-operative radiation therapy)
IMRT (intensity modulated radiation therapy)
Stereotactic radiotherapy
✔✔the pregnancy policy's purpose is to - ✔✔define rules for student pregnancy.
✔✔Pregnancy Policy's definition - ✔✔Female students have the option of whether or
not to inform program officials of their pregnancy. "Declared pregnant woman means a
woman who has voluntarily informed the licensee, in writing, of her pregnancy and the
date of conception. The declaration remains in effect until the declared pregnant woman
withdraws the declaration in writing or is no longer pregnant." 10CFR Part 20, section
20.1003
, ✔✔Pregnancy Policy 3.1 - ✔✔To declare a pregnancy, a student shall write a letter to
the Program Director that provides a name, date, estimated date of conception and
delivery. The letter must be signed by the student.
✔✔Pregnancy Policy 3.2 - ✔✔The student may revoke their declaration of pregnancy in
writing at any time. If the declaration is not withdrawn, the written declaration will be
considered expired one year after submission.
✔✔Pregnancy Policy 3.3 - ✔✔The declared pregnant student will be given a secondary
radiation monitoring device to be worn at waist level under any protective apparel.
✔✔Pregnancy Policy 3.4 - ✔✔The student will have several options:
3.3.1 Continue in the program as scheduled and graduate with peers.
3.3.2 Exit the program and join the next cohort.
3.3.3 Reinstatement policy will be followed.
✔✔Pregnancy Policy 3.5 - ✔✔Because the didactic and clinical internship are offered in
a lock step fashion it is not permissible for a student to continue classes and complete
the internship out of sequence.
✔✔Pregnancy Policy 3.6 - ✔✔In the event a declared pregnant student receives as
dose of 0.05 rem (0.5 mSv) in any month of pregnancy, or greater than 0.5 rem (5 mSv)
at any time during the pregnancy, the student will be removed from internship until after
delivery.
✔✔What is the National Accreditor? - ✔✔JRCERT-Joint Review Committee on
Education in Radiologic Technology
✔✔What are the three main Credentialing Organizations? - ✔✔ARRT-American
Registry of Radiologic Technologists
MDCB-Medical Dosimetrist Certification Board
ABR-American Board of Radiology
✔✔Professional Societies on the National level include - ✔✔ASRT-American Society of
Radiologic Technologists
AAMD-American Association of Medical Dosimetrists
✔✔Professional Society on the State level include - ✔✔CSRT- California Society of
Radiologic Technologist
✔✔Four main types of radiation departments - ✔✔free standing: privately owned
University Medical Center: Researched based, residents, interns
Community based: non-profit
