Consolidated guidance about medical, academic, and industrial uses of nuclear materials is published in "Consolidated Guidance About Materials Licenses" (NUREG-1556, Volumes 1-21).

Web (HTML) versions of some guidance documents are available in our NRC Formal Publication Collection. Some are also are available in NRC's Agencywide Documents Access and Management System (ADAMS) (see our table listing their availability).

Regulatory guides are issued in 10 divisions and are intended to aid licensees in implementing regulations. The guides most applicable to medical, industrial, and academic uses of nuclear materials are in

The following regulatory guides (RGs) in Division 8 are the ones most relevant to medical, industrial, and academic uses of nuclear material:

  • RG 8.7 - Instructions for Recording and Reporting Occupational Radiation Exposure Data
  • RG 8.9 - Acceptable Concepts, Models, Equations, and Assumptions for a Bioassay Program
  • RG 8.13 - Instruction Concerning Prenatal Radiation Exposure
  • RG 8.15 - Acceptable Programs for Respiratory Protection
  • RG 8.18 - Information Relevant to Ensuring that Occupational Radiation Exposures at Medical Institutions Will Be as Low as Reasonably Achievable
  • RG 8.20 - Applications for Bioassay for I-125 and -131
  • RG 8.21 - Health Physics Surveys for Byproduct Material at the NRC-Licensed Processing and Manufacturing Plants
  • RG 8.25 - Air Sampling in the Workplace
  • RG 8.29 - Instruction Concerning Risks from Occupational Radiation Exposure
  • RG 8.32 - Criteria for Establishing a Tritium Bioassay Program
  • RG 8.34 - Monitoring Criteria and Methods To Calculate Occupational Radiation Doses
  • RG 8.35 - Planned Special Exposures
  • RG 8.36 - Radiation Dose to the Embryo/Fetus
  • RG 8.37 - ALARA Levels for Effluents from Materials Facilities

Web (HTML) versions of some regulatory guides are available for viewing or downloading. Those available are highlighted in the index to our Regulatory Guide document collection. All active final and draft guides are also available in ADAMS.

Guidance on preparing required reports is available in:

  • NUREG/BR-0006 - Instructions for Completing Nuclear Material Transaction Reports
  • NUREG/BR-0007 - Instructions for the Preparation and Distribution of Material Status Reports

Generic communications are NRC's primary method of sending information to specific classes of licensees. There are several types:

Newsletters are another way of sending information to NRC licensees. The NMSS Quarterly Newsletter (NUREG/BR-0117) contains information about medical, industrial, and academic uses of nuclear material.
