Check a California RHB Certificate or Permit
Use this California radiology license verification guide when you need to confirm a radiologic technologist, limited permit X-ray technician, fluoroscopy permit holder, nuclear medicine technologist, or related RHB certificate/permit.
California’s official wording is usually certificate, permit, authorization, or Radiologic Health Branch record. Searchers often type “radiology license,” so this guide uses plain language and routes you to the correct official source.
California Radiology Lookup Desk: Choose the Correct Task
Most visitors do not need a long explanation first. They need the right official route. Choose your task below, then use the step-by-step section before you rely on the result.
Verify a radiology tech or permit holder
Use the RHB X-ray and NMT certificate/permit search when you need to verify a person’s current RHB authorization.
Open RHB searchPrint or save your RHB document
Certificate and permit holders can use the online printing process after searching by certificate type and number and verifying identity details.
See printing instructionsRenew certificate or permit
Renewal may require mailed renewal application, renewal fee and continuing education evidence based on your certificate/permit type.
Check renewal/CEThe person does not show
The RHB search focuses on valid/current records. Search errors, expired authorization, processing delay, or wrong category can cause no result.
Fix no-result searchCheck X-ray machine/facility registration
Do not use a person lookup for a machine or facility question. CDPH separates individual permits from machine registration.
Open facility searchNeed verification for another state?
If an employer, school, board or another state requires formal verification, use RHB’s out-of-state/license verification route.
See formal verification stepsCalifornia Radiology License Verification: Exact Lookup Steps
Use these steps for a California radiologic technologist, CRT, limited permit X-ray technician, fluoroscopy permit holder, nuclear medicine technologist, supervisor/operator, or another RHB certificate/permit holder.
Open the official RHB certificate/permit search
Start with the California Radiologic Health Branch X-ray and NMT certificate/permit search. Use private directories only as a clue, never as final proof.
Search with the strongest identifier first
Use certificate/permit type and number when available. If you only have a name, search carefully and compare every result before relying on it.
Match the person and authorization type
Confirm full name, certificate or permit type, number, expiration, and whether the authorization shown fits the exact work being performed.
Check whether another license also matters
For healing-arts licentiates such as MD, DO, DPM, DC or PA, the RHB authorization may depend on the related healing-arts license remaining current and valid.
Save dated proof
Save the date checked, official source, name searched, certificate/permit number, authorization type, expiration, and who completed the verification.
Open the state search after you know what to enter and which fields to compare.
Open California RHB certificate/permit searchWhat to Enter in the RHB Search Tool
Most lookup failures happen because users search the wrong field or use a name when a certificate number would be safer.
| What you have | Best search method | Micro-tip |
|---|---|---|
| Certificate or permit type + number | Search by certificate type and number. | This is the strongest route and is also used for online printing. |
| Only full name | Search last name and first name. | Try legal name, former name, married name and hyphenated spelling if needed. |
| Employer credentialing file | Use number first, then name as a backup. | Document the official source, date and exact authorization type. |
| Applicant says “I applied” | Do not rely on lookup until an authorization appears or RHB confirms. | Application receipt is not the same as permission to use X-rays. |
| Facility or equipment question | Use X-ray machine registration search. | Facility registration does not verify a person’s certificate/permit. |
What the California RHB Search Result Proves — and What It Does Not
The RHB search is helpful, but it has limits. It is built around valid/current X-ray and Nuclear Medicine technology certificates and permits.
| Result or issue | Easy meaning | What to do next |
|---|---|---|
| Current record appears | The person appears in the official RHB system for that certificate or permit type. | Match name, type, number and expiration. Save dated proof. |
| No result | The person may be expired, not currently valid, searched incorrectly, under another name, or still processing. | Try number, exact name, former name and correct certificate/permit type. Use formal verification if needed. |
| Wrong type found | The person may hold a different authorization from the one needed for the work. | Confirm whether the task requires CRT, limited permit, fluoroscopy, mammography, NMT or another category. |
| Healing-arts permit issue | A related MD, DO, DPM, DC or PA license may also need to be current and valid. | Check the appropriate healing-arts board/license route in addition to the RHB authorization. |
| Facility record needed | You are checking an X-ray machine or facility, not a person. | Use the X-ray machine/facility registration route instead of the person permit search. |
If an authorization is expired or not currently valid, it may not appear in the public RHB certificate/permit search. A no-result search is not always the same as “never certified.”
No Result Found? Fix These California RHB Lookup Problems
No result can happen because of spelling, name changes, expired authorization, wrong category, facility/person confusion, or because formal verification is required.
Search by certificate or permit number
If the applicant or employee has the number, use it first. Number search is more reliable than name-only searching.
Try legal and former names
Try maiden name, married name, hyphenated last name, middle initial and the spelling used on the certificate/permit record.
Remember the search focuses on current records
Expired or not-current authorizations may not show. Ask for renewal proof or use formal RHB verification if required.
Check the correct authorization category
A CRT, limited permit technician, fluoroscopy permit holder, supervisor/operator and NMT record are not the same thing.
Machine registration is a separate search
If your task is checking a facility or X-ray machine registration, use the facility route rather than the person lookup.
Initial or renewal authorization may still be processing
If the person recently applied or renewed, check again later and use RHB instructions if the deadline is urgent.
Which California Radiology Certificate or Permit Are You Checking?
Do not stop at “radiology license.” California RHB records use specific certificate and permit categories. The correct category depends on the person’s role and the work being performed.
| Type or role | What it usually relates to | Lookup caution |
|---|---|---|
| Certified Radiologic Technologist / CRT | Diagnostic or therapeutic radiologic technology certificate category. | Confirm modality and any related permit needed for the role. |
| Limited Permit X-ray Technician | Limited scope X-ray permit authorization. | A limited permit is not the same as a full CRT authorization. |
| Fluoroscopy permit | Fluoroscopy use by eligible permit holders. | Examination-required and examination-not-required application routes are different. |
| Mammographic Radiologic Technologist | Mammography certificate/authorization area. | Mammography-specific continuing education may apply at renewal. |
| Nuclear Medicine Technologist / NMT | Nuclear medicine technology certificate area. | Use NMT-specific form and search route, not a generic CRT form. |
| Supervisor and Operator | RHB supervisor/operator certificate or permit category. | Use the specific certificate/permit number and type when available. |
Individual Certificate vs X-Ray Machine Registration
California separates a person’s RHB certificate/permit from an X-ray machine or facility registration. This is one of the most common lookup mistakes.
Use RHB certificate/permit search
- Radiologic technologist or CRT.
- Limited permit X-ray technician.
- Fluoroscopy permit holder.
- Nuclear medicine technologist.
- Supervisor/operator certificate or permit.
Use X-ray machine registration search
- Machine registration is not a person’s certificate.
- Facility registration does not prove a person can perform the work.
- A person’s RHB permit does not replace facility registration.
- Radioactive material and general licensed devices may use other RHB routes.
Use this route only when your task is X-ray machine or facility registration, not a person’s radiology tech certificate/permit.
Open X-ray machine registration searchHow to Print or Save a California RHB Certificate/Permit
Certificate and permit holders can use the online printing process to access their own authorization document. This is different from a public employer lookup.
Search by certificate type and number
Use the RHB search option for certificate type and certificate/permit number. This is the route CDPH describes for electronic document access.
Click “Verify License” when your record appears
The verification page opens after the record is displayed. Complete the captcha before entering private identity details.
Enter last 4 SSN/ITIN and DOB
If RHB does not have DOB, SSN or ITIN in its records, electronic document access may fail and the record may need updating.
Download, print or save the document
If the verification page displays “VERIFIED,” use the download link and save a copy for your facility, employer or personal records.
Use this when the certificate/permit holder needs to print or save their own RHB document.
Open RHB online printing guideCalifornia RHB Renewal and Continuing Education Checklist
RHB renewal is not just a search result. Certificate and permit holders generally renew every two years and must submit renewal items and continuing education evidence where required.
Prepare these before expiration
- Renewal application.
- Required renewal fee.
- Continuing education evidence where required.
- Current mailing address so renewal notices arrive.
- Time for U.S. mail submission and processing.
Check your certificate/permit type
- CRTs: 24 CEC related to X-ray use on the human body.
- All CRTs: 4 of the 24 CEC must be digital radiography.
- Fluoroscopy permit holders: 4 of the 24 CEC must be radiation safety for clinical fluoroscopy use.
- Mammography certificate holders: 10 of the 24 CEC must be mammography-specific.
- Limited Permit X-ray Technicians: 24 CEC related to X-ray use on the human body.
Do not wait for the final week. Renewal notices are mailed before expiration, but the holder is still responsible for meeting renewal, fee and CEC requirements.
Open RHB renewal and CE informationApplied Already? California RHB Processing Timeline and No-Record Issues
A person who recently applied may not appear in the public search immediately. The correct next step depends on whether an exam is required, documents are missing, or the application has not been accepted yet.
RHB reviews acceptability
Applicants complete, print and mail the correct X-ray/NMT permit or certificate application with required fee and documentation.
RHB sends application status
RHB notifies applicants whether the application is acceptable, exam steps are needed, or the application is not accepted with next steps.
Exam vs no-exam route matters
Permits/certificates may be issued after successful exam completion when required, or after an acceptable no-exam application is processed.
Application is not authorization
An application, payment, exam eligibility or training completion is not the same as a current certificate or permit listing.
Name mistakes can delay exam/application
RHB application PDFs warn that failure to use your full legal name can cause examination-entry problems.
Use alternate address if needed
Application PDFs say information except SSN/ITIN may be public under PRA. Use a P.O. Box or alternate address if appropriate.

California Radiology License Verification FAQs
These answers cover the most common California radiology tech lookup, certificate, permit, renewal, printing and no-result questions.
How do I verify a California radiology tech license online?
Use the official California CDPH Radiologic Health Branch X-ray and NMT certificate/permit search. Search by certificate/permit details or name, then match the person, authorization type, number and expiration.
Is California radiology license verification the same as RHB certificate search?
For many users, yes. California official pages often use certificate, permit, authorization or Radiologic Health Branch wording, while searchers often call it a radiology license.
What can I verify in the California RHB search?
The RHB search is used for valid/current X-ray and Nuclear Medicine technology certificates and permits, including categories such as radiologic technologist, limited permit X-ray technician, fluoroscopy permit and NMT records.
Why does a California radiology tech not show in the lookup?
The record may be expired, not currently valid, searched under a different name, listed under another certificate/permit type, still processing, or not available through the public current-record search.
Does the California RHB search show expired certificates?
The RHB search is focused on valid and current certificates and permits. Expired or non-current authorizations may not display in the public search.
How do I print my California RHB certificate or permit?
Use the RHB online printing instructions. Search by certificate type and number, click Verify License, complete captcha, enter the last four digits of SSN/ITIN and date of birth, then download or print if verified.
Is an X-ray machine registration the same as a radiology tech permit?
No. X-ray machine or facility registration is separate from a person’s radiologic technology certificate or permit. Use the facility registration route for machines and the RHB certificate/permit search for people.
How often do California RHB certificates or permits renew?
Many RHB certificates and permits renew every two years. Renewal may require a mailed renewal application, fee and continuing education evidence depending on the certificate or permit type.
How do I get formal California RHB verification for another state?
Use the RHB out-of-state or license verification instructions. Formal verification may require an authorization/release form, the California X-ray certificate or permit number and email submission to RHB.
Who do I contact for California radiology license verification help?
Contact the California Department of Public Health Radiologic Health Branch. Prepare the person’s full legal name, certificate or permit number, authorization type and the exact lookup, renewal, printing or verification issue.
