Radiation Control Accepted Radiation Safety Training Course List

A list of accepted radiation safety training courses is available as a courtesy to you. We do not recommend one course over another. It is a resource for you to use to find the course that best suits your needs or used to verify previous training documentation for new radiography employees.

The list of Accepted Radiation Safety Training Courses (PDF, 66KB) is divided into use categories; Industrial Radiography, Well Logging and Tracer Studies, Well Logging Only, Portable Gauge, Fixed Gauge, Spinning Pipe and X-ray Fluorescence.

Applicable Regulations

The requirements of the following sections of Title 25, Texas Administrative Code (TAC), Chapter 289 apply to the use of radioactive material in moisture/density, spinning pipe and fixed gauge operations and X-ray fluorescence analyzers:

Radiation Control will provide one printed copy of the applicable sections of the rules. It is the licensee's responsibility to ensure that its facility and any additional authorized sites are provided with copies of the applicable rules. These rules may be duplicated or can be downloaded from this site. For a charge, you may request rules on disk or additional hard copies.

Completing the Application

Complete and submit RC 252-2, Radioactive Material License Application (PDF, 67KB).

Item 1. Legal Business Name and Mailing Address of Applicant

Enter the company name and mailing address. The name (or DBA) should correspond to the name on RC 252-1, Business Information Form (PDF, 54KB). The applicant is the organization or person legally responsible for the possession and use of the radioactive material. The address specified here must be your mailing address for correspondence. This may or may not be the same as the address where the material will be stored or used.

NOTE: Radiation Control will not issue a license addressed to a company or person residing outside the state of Texas.

Item 2. Location(s) at Which Radioactive Material Will Be Used

Specify all locations of storage or use by designating the street address, city, and state. A post office box address is not acceptable. Also, indicate whether the radioactive material will be used at temporary job sites throughout Texas.

Item 4. Location Where Records Will Be Kept

Provide the appropriate information even if it is the same as the mailing address.

If applying for additional authorized use/storage sites, specify which site will be designated as the main site (e.g., home office or office location of the Radiation Safety Officer - RSO). Copies of all required records need to be maintained for Radiation Control review at the designated main site. Additionally, if the records location is different from the radioactive material storage site, the site will be billed as an additional authorized use site.

Item 6. Radiation Safety Officer (RSO)

The RSO is the person designated to be responsible for the day-to-day radiation safety program. The RSO maintains all records required by the Radiation Control rules, and is the primary contact with Radiation Control on matters pertaining to the license and the use of radioactive materials. The RSO must have the authority to enforce radiation safety policy, suspend activities deemed unsafe, and require remedial action when necessary. Submit the qualifications outlined above for RSO qualifications.

Item 7. Radioactive Materials Data

Information necessary for this item is available from the Nuclear Regulatory Commission's Radioactive Sealed Source and Device Registry.

This registry is a database of safety evaluations of devices registered with the Nuclear Regulatory Commission. The registry can be used to search for specific devices and manufacturers. The evaluations typically provide a description and safety information about the device, model numbers, manufacturer/distributor, sealed source model designation, isotope and maximum activity for the device, and leak test interval.

Item 15. Certification

The application shall be dated and signed by a representative of the corporation or legal entity who is authorized to sign official documents and to certify that the application contains information that is true and correct to the best of the applicant's knowledge and belief.
