I. Introduction

The U.S. Nuclear Regulatory Commission (NRC) is issuing a revision to an existing guide in the agency's “Regulatory Guide” series. This series was developed to describe and make available to the public information such as methods that are acceptable to the NRC staff for implementing specific parts of the agency's regulations, techniques that the staff uses in evaluating specific problems or postulated accidents, and data that the staff needs in its review of applications for permits and licenses.

Revision 2 of Regulatory Guide 8.18, “Information Relevant to Ensuring that Occupational Radiation Exposures at Medical Institutions will be As Low As is Reasonably Achievable,” was issued with a temporary identification as Draft Regulatory Guide, DG-8037.

This guide is directed specifically toward medical licensees and recommends methods that the staff of the NRC considers acceptable to maintain occupational exposures as low as is reasonably achievable (ALARA) in medical institutions. In a medical institution, certain persons other than employees are exposed to radiation from licensed radioactive material. These persons include visitors and patients other than those being treated with radioactive material. This guide addresses the protection of these individuals. The content of this guide is also applicable to veterinary medical institutions, insofar as specific diagnostic or therapeutic procedures are performed. Similar protection practices are applicable for keeping employee and visitor exposures ALARA, whether the patients are animal or human.

II. Further Information

In January 2010, DG-8037 was published with a public comment period of 60 days from the issuance of the guide. The public comment period closed on March 19, 2010.
