Radioactive Material Licensee
Contact Information for North Dakota Licensees is available as a text formatted (*.txt) file:
There are many types of users of radioactive materials within North Dakota. Licensee categories are listed below:
Unsealed radiopharmaceuticals or the radiation from sealed sources administered to patients for diagnostic or therapeutic purposes. Most hospitals and some major clinics have nuclear medicine departments. Some clinics and certain private physicians may also be licensed to use radioactive materials for only diagnostic procedures.
Unsealed radiopharmaceuticals or the radiation from sealed sources administered to patients for diagnostic purposes from a mobile unit instead of a fixed facility. This type of license is similar to Medical license but is smaller in scope, while performing at various temporary locations.
Small sealed radioactive sources used in permanently mounted test equipment to measure the density of material within a pipe or the level of material in a vessel. These are used in power plants and other industrial applications.
Radiation from sealed radioactive sources is used at various locations to create images of the insides of objects, for example, to inspect metal castings or welds for internal flaws.
Radioactive sources used in underground well logging applications at various locations. Types of well logging include: Gamma Ray, Spectral Gamma Ray, Radioactive Tracer, Density Logs, Neutron Logs, Pulsed Decay Time and Induced Spectrometry. The information produced during logging can be used to determine stratigraphic profiles, and also the porosity/density of the formation.
Small sealed radioactive sources are used in portable test equipment to measure moisture and/or density of construction materials, road beds, roofing, or agricultural land. The gauges are susceptible to theft and damage by road construction equipment. These are used by government and industry at various construction sites.
Small sealed radioactive sources are used in portable test equipment to measure lead content, density of materials and thickness of pipe wall. The gauges are also susceptible to theft and damage by heavy equipment.
The use of gamma radiation from sealed sources to irradiate materials such as blood and blood products to prevent engraftment and proliferation of lymphocytes capable of mounting an immune response against the recipient. Irradiators may also be used to calibrate dosimeters. These devices are used at blood banks, calibration facilities and universities.
Unsealed radioactive materials may be used to study living systems and to improve or test products or materials. Users may include biotechnology firms, colleges and universities, and testing labs.
Sealed radioactive sources with known amounts of activity used as standards for the testing and calibration of radiation detection equipment.
Sealed and/or unsealed radioactive sources used to study living systems and to improve or test products, materials or processes for the purpose of education, research and/or development.
