12、g radioactive materials (NORM) has been prepared by API to provide relevant guidance to oil and gas operating companies. This publication is under the jurisdiction of the API Production Waste Issues Group under direc-tion of the Executive Committee of Environmental Conservation.Cooperative efforts b
13、etween federal and state regulatory agencies, industry, and other inter-ested parties are expected to generate much useful information regarding NORM in the next several years. This document will be updated as new scientific information becomes avail-able concerning NORM.Individuals and organization
14、s using this bulletin are cautioned that requirements of federal, state, and local regulations are constantly evolving and should be reviewed to determine whether the information in this bulletin is consistent with current laws and regulations.API makes no representation, warranty, or guarantee in c

48、oducing and processing equipment. The purpose of this document is to inform oil and gas operators of the possible presence of NORM and to provide relevant information on protecting workers, the public, and the environment. The objective of this document is to provide general information to users so
49、that they have an under-standing of the fundamental radiation issues associated with the management of NORM. Issues where the advice of a professional health physicist, industrial hygienist, or other technical expert may be useful are identified and guidance provided. Readers are advised to contact their state regulatory office and work very closely with that office on all NORM issues.Radiation can result from both man-made and natural sources. Man-made sources include dental x-rays and well logging tools. Natural sources of radiation include the sun (cosmic rays) and radiation f
