FOREWORD The Second Conference on Radiation Protection and Dosimetry was held during October 31 - November 3, 1988, at the Holiday Inn - Crowne Plaza Hotel in Orlando, Florida. This meeting was designed with the objectives of promoting communication among applied, research, regulatory, and standards personnel involved in radiation protection and providing them with sufficient information to evaluate their programs. To facilitate meeting these objectives, a technical program consisting of more than 75 invited and contributed oral presentations encompassing all aspects of radiation protection was prepared. General topics considered in the technical sessions included external dosimetry, internal dosimetry, calibration, standards and regulations, instrumentation, accreditation and test programs, research advances, and applied program experience. In addition, special sessions were held to afford attendees the opportunity to make short presentations of recent work or to discuss topics of general interest. This document provides a summary of the conference technical program and a partial collection of full papers for the oral presentations in order of delivery. Starred titles in the program summary indicate those presentations which have papers included in these proceedings. In the interest of attracting persons with a variety of experience and preparing a program which contains the most current information, full papers were not required of speakers. Thus, this collection does not contain papers for all presentations. A complete collection of abstracts for this meeting is available in the program and abstracts book which was distributed at registration. The editors are grateful to the members of the Conference Coordination Committee and the Technical Program Committee for their efforts in making this conference a success. The technical program was informative and comprehensive, and ye hope that these proceedings will be useful to all attendees. Charles S. Sims Richard E.
