How to Verify a Nuclear Medicine Technologist Certification
Nuclear medicine technologists administer radioactive drugs and operate gamma cameras for diagnostic imaging. Two national bodies certify them: NMTCB and ARRT. Most states also require licensure. Here is how to verify both.
Quick answer
Verify NMTCB credentials (CNT — Certified Nuclear Medicine Technologist) at nmtcb.org. Verify ARRT credentials (CNMT — Certified Nuclear Medicine Technologist) at arrt.org. Both are widely accepted; confirm which your institution requires. Also verify state licensure — most states with nuclear medicine programs require a separate state license or registration.
NMTCB vs. ARRT: two certification pathways
Nuclear medicine technologists can certify through either of two national bodies:
| Body | Credential | Verify At |
|---|---|---|
| NMTCB (Nuclear Medicine Technology Certification Board) | CNT (Certified Nuclear Medicine Technologist) | nmtcb.org |
| ARRT (American Registry of Radiologic Technologists) | CNMT (Nuclear Medicine Technology) | arrt.org |
Both are nationally recognized and accepted by most employers and state licensing boards. ARRT technologists may also hold PET (Positron Emission Tomography) and NCT (Nuclear Cardiology Technology) post-primary credentials through ARRT. NMTCB offers the CNMT with a PET specialty add-on.
How to verify NMTCB certification
- Go to nmtcb.org
- Navigate to the credential verification tool
- Search by technologist name or CNT number
- Confirm: Active status, PET specialty if applicable, and expiration/renewal date
NMTCB certifications are valid for 5 years and require continuing education for renewal. NMTCB also offers a Nuclear Cardiology Technology (NCT) specialty certification — verify separately if applicable.
How to verify ARRT certification
- Go to arrt.org
- Use the “Verify Credentials” public lookup tool
- Search by technologist name or ARRT ID number
- Confirm: primary certification (CNMT), any post-primary credentials (PET, NCT), Active status, and expiration
ARRT credentials renew on a 2-year cycle through continuing education (CE) requirements. The ARRT lookup shows all credentials held by a technologist, not just nuclear medicine — useful for multi-credentialed technologists.
State licensure
Many states regulate nuclear medicine technologists through their radiation control programs or department of health. State licenses are required in addition to national certification in most regulated states.
State radiation control programs
Nuclear medicine technologists working with radioactive materials must comply with state radiation control regulations, which are enforced by state health departments or radiation control programs — separate from general healthcare licensing. Some states require a specific nuclear medicine technologist license; others require only national certification. Verify with the state radiation control program in the state of practice.
Red flags
- Credential not found at nmtcb.org or arrt.org
- Expired ARRT or NMTCB certification — both require periodic renewal
- No state license in a state that requires nuclear medicine technologist licensure
- PET technologist without the NMTCB PET specialty or ARRT PET post-primary credential
- Technologist claiming credentials from both bodies but one cannot be verified
Verification checklist
- 1. Determine which certification the institution requires: NMTCB CNT or ARRT CNMT (or both)
- 2. Verify at nmtcb.org and/or arrt.org — confirm Active status and expiration
- 3. For PET roles: confirm PET specialty credential is active
- 4. Check state radiation control program requirements and verify state license if required
- 5. Confirm training program was JRCNMT-accredited if required by the role
Verify nuclear medicine technology program accreditation
Nuclear medicine technology programs are accredited by JRCNMT. Use VerifyED to confirm whether a school's program meets accreditation requirements.
