Radiation Safety Exam Information

Section 1: Introduction

The NMTCB has developed a post-primary certification exam for radiation safety. The NMTCB(RS) credential is designed to establish a technologist's expertise in all aspects of RAM and CT radiation safety issues, while also verifying their competency in fluoroscopy, X-ray, and MRI safety matters.

The NMTCB(RS) exam is administered on specific dates each year. Once an applicant's eligibility is confirmed, they will be able to schedule to sit for the exam at the next scheduled date(s). The NMTCB(RS) exam will be administered nationally by IQT, Inc. Specific testing locations are available to view at IQT Testing Locations.

Although every attempt will be made to allow you to take the NMTCB(RS) examination at the location of your choice, please be aware that not all testing centers are available every day of the year and some have limited hours available. For this and similar reasons, you may not be able to take the exam at the site closest to you. NMTCB and our testing company, Iso-Quality Testing, will work to find the closest available test center location on either day for eligible candidates.

The first administration of the NMTCB Radiation Safety exam was Friday, November 3, 2017 with the second exam offered on Friday, August 17, 2018, third exam offered on August 16 and August 17, 2019 and a fourth exam offered from August 12-15, 2020. Exam results are processed and mailed via USPS in approximately four to six weeks from the date of exam.

A candidate may take the exam a maximum of one (1) time within a 12 calendar month period.

The examination consists of 200 multiple choice questions with three hours and 30 minutes to complete the exam. The application fee is $185.00.

These instructions will familiarize you with the NMTCB's application and examination administration procedures. It is important that you understand and follow the procedures outlined in these instructions. Read them entirely and carefully before completing and submitting your application. You are responsible for knowing what is contained in these instructions. You will be more comfortable at the test site if you first familiarize yourself with the procedures and policies relating to the examination. Refer to these instructions for reference and contact the NMTCB office at the address at the bottom of this page if you have any questions. The NMTCB application and instructions are revised annually to reflect changes in policies and eligibility requirements. It is important that you complete and return the current application form.

The NMTCB does not discriminate against any individual on the basis of age, sex, race, religion, physical impairment, marital status, or national origin.

A total of 184 individuals are Active NMTCB(RS) Certificants.

Schedule/Reschedule/Cancellation of Examination

The NMTCB Specialty examinations are offered through IQT, Inc. A list of the testing centers and their locations is available to NMTCB candidates on the IQT website.

The NMTCB(RS) Specialty Examination is available on select dates. Once your application is approved, you may schedule yourself to sit for the exam on a date that the exam is being offered. Once you are determined eligible for the exam, you will be emailed instructions on how to schedule your examination day/time through IQT. You are expected to make an appointment and appear for the examination within your testing period.

If you fail to show up for your examination at the scheduled time, do not have the proper identification, or do not have your admission document, you will not be allowed to sit for your exam. You will be considered a "No-Show", your examination fees will be forfeited, and you will be required to re-register and pay all fees prior to sitting for the exam. However, if an issue arises that prohibits you from making it to your scheduled exam, you may reschedule prior to (5) calendar days before your scheduled exam date by contacting IQT at 1-866-773-1114. You may be required to pay a rescheduling fee to process your request. If it is less than (5) calendar days, you will not be allowed to cancel or reschedule your exam unless one of the following 4 situations have occurred:

  • Jury Duty
  • Death in the immediate family
  • Military Deployment
  • Sickness

The immediate family is defined as a person's grandparents, parents, spouses, siblings and children.

If you experience any of the above, you MUST provide IQT with proper documentation before being rescheduled to a new date. Documentation must be submitted to IQT within 10 calendar days of your missed examination or it will not be considered for a reschedule.  If none of the above are the reason for wanting to reschedule or cancel your exam less than 5 days prior to your exam date, then you will not be allowed to reschedule or cancel your exam.

If your area is experiencing inclement weather, it is your responsibility to contact your testing center to confirm if it is closed or delayed in opening. Most likely there will be a voice message on the testing center’s phone system to notify candidates of any change in business hours during the inclement weather. If you are unable to take your examination due to the inclement weather, you must contact IQT directly at 1-866-773-1114 or 1-727-733-1110 to reschedule your examination for a later date.

Candidates who fail to make an appointment during the eligibility period will have their application fee rolled over one time to apply towards the next exam date. This request must be submitted in writing to NMTCB and a candidate cannot be scheduled for an exam date at the time of the request. Candidates who fail to sit for the exam after the one time roll over opportunity will be required to submit the full application fee in order to be reactivate the application and be considered eligible. 

Returned Checks

Checks returned by the bank to the NMTCB office for any reason are subject to a $45.00 returned check fee. The returned check fee and the replacement fee must be submitted in certified funds only (money order, cashier's check, etc.). A personal check cannot be accepted as replacement. All financial obligations to the NMTCB must be met before the eligibility letter is sent.

Reactivation of Application

If you have previously unsuccessfully taken the NMTCB(RS) Examination, your application will remain on file with the NMTCB. Eligible candidates may repeat the examination by reactivating their eligibility with a written request to the NMTCB along with the current processing fee. A candidate may take the exam a maximum of one (1) time within a 12 calendar month period. For re-examination, the eligibility criteria must still be met (current NMTCB, ARRT(N) or CAMRT nuclear medicine certification). Applicants who were determined ineligible to take the examination, but who later meet the current eligibility requirements, may reapply, pay the current processing fee and reactivate their application. To reactivate an application you can visit the application page here.

Section 5: Privileges and Responsibilities

Passing the NMTCB(RS) Examination entitles you to certain privileges and obligates you to fulfill certain responsibilities. These are summarized below:

Privileges of Certification:

CERTIFICATE: The most immediate benefit of certification is your certificate which will be mailed to you approximately four (4) - six (6) weeks after successful completion of the examination.

CREDENTIALS: Upon certification, you will also be granted the right to use the credential "NMTCB(RS)" after your name.

ANNUAL CERTIFICATION CARD: A personalized pocket-size annual certification card will be mailed to you after you receive your examination results. Most certificants carry the card with them. The certification card is a convenient method to provide your employer, governmental agencies and others with documentation that you are certified and registered in NMTCB(RS). An updated certification card will be mailed to you annually upon payment of the annual registration fees.

DIRECTORY LISTING: The names of all currently registered NMTCB(RS) technologists are listed in the "NMTCB Directory of Certified Nuclear Medicine Technologists", on the NMTCB website. The directory is made available only to other NMTCB certificants.

NMTCB NEWSLETTER: The NMTCB NEWS, published semi-annually, is provided to all certificants of nuclear medicine technology, CT, radiation safety, nuclear cardiology technology, PET, and NMAA. NMTCB NEWS covers topics of concern to certified technologists, trends in NMT education, developments in health care, nationwide salary comparisons, and other professional information.

Successful completion of the NMTCB(RS) post primary exam will be recognized by the NMTCB as the equivalent of 24 hours of CE

Responsibilities of Certification:

ANNUAL REGISTRATION: Perhaps the greatest responsibility of certification is annual registration. Once you are certified by the NMTCB, you remain certified and certification cannot be revoked without due process. It is necessary for you to register your certification annually with the NMTCB. Your annual registration fee pays for the privileges you enjoy as an NMTCB Certificant. More importantly, your annual registration fee supports the certification process for nuclear medicine professionals, thereby enhancing the profession of nuclear medicine technology.

Responsibilities of NMTCB(RS) certificants include maintaining an active nuclear medicine certification/registration in order to complete the yearly renewal of your NMTCB(RS) certification. You will be allowed to renew your NMTCB(RS) certification only if you maintain active nuclear medicine certification/registration.

The NMTCB(RS) Certification is valid for 10 years. In order to recertify at the end of 10 years, the NMTCB(RS) certificant must show:

  1. All candidates for recertification should have an Active nuclear medicine technology certification (NMTCB, ARRT, CAMRT)
  2. If the candidate can show evidence that they were listed on a RAM license any time within the past 7 years, (produce a copy of the license showing that their name is on it) they will automatically be renewed for another 10 year period
  3. If the candidate is not listed on a RAM license, but has performed radiation safety duties any time within the past 7 years under direction of an RSO and can provide a letter from the RSO with the RAM license # corresponding to the facility were the duties were performed, the candidate will automatically be renewed for another 10 year period.
  4. A candidate that does not qualify for (b.) or (c.) can sit for the exam again.

Section 6: Appeals Procedure

Every effort is made to ensure that the NMTCB examination procedures are reasonable and that fair and equitable treatment is accorded to all applicants. To ensure fairness and a right of redress in the evaluation and processing of applications, examination procedures, and certification activities, the Directors of the NMTCB have established a formal appeals procedure which you must follow for appeal of any NMTCB policy, requirement, or decision.

If you are dissatisfied with or adversely affected by any action or decision of the administration of the NMTCB, you have the right to appeal such action or decision. If you wish to appeal any action or decision, your appeal must follow these guidelines which can be found here.
