Book Description
The purpose of this study was to develop mathematical methods to assess the biological hazards of space radiation and to program these methods for the IBM 7090 using FORTRAN language. A semianalytical approach was utilized to write machine programs for geocentric trajectories and a model astronaut inside a space vehicle. The trajectory program is used to solve the two body problem with pertubations to correct for the oblateness of the earth. The earth's magnetosphere is the space of principle interest for lunar missions, therefore lunar impact and return trajectories are considered to be two body geocentric orbits. An astronaut's head and torso are represented by two right elliptical cylinders. This model is placed inside a mathematically described space vehicle with known thicknesses in designated areas. An existent mahine program was utilized to define the radiative environment in McIlwain (B, L) coordinates and supplemental computer programs were used to determine radiation doses resulting from electron and proton environments. Results from the CARS program are obtained with a small amount of maching time. For example, one tenth (.1) of an hour was required to determine the radiation dose due to two spectra (electrons and protons) at ten points in the model astronaut within the APOLLO Command Module (CM) for a given orbital mission.

Book Description
Analytical methods and computer programs were developed at Douglas for use in establishing the radiation shielding requirements of space vehicle systems. Current techniques for performing space radiation shielding analyses are reviewed in the context of the digital computer programs in which they have been incorporated. Calculations dealing with the transport of primary charged particles and secondary reaction products through matter are performed by the CHARGE program for geometrically simple systems. The calculation of radiation levels in geometrically complex vehicle-shield configurations is accomplished by the SIGMA program, using the QUAD generalized quadratic surface geometry package. Procedures for ascertaining the optimal distribution of shield mass subject to specific dose design criteria are presently under development.

Book Description
This newly published book is intended for dual use as a textbook for students in radiation shielding courses and a reference work for shielding practitioners. It emphasizes the principles behind techniques used in various aspects of shield analysis and presents these principles in many different contexts. This approach is intended to provide a strong base of understanding in order to facilitate use of the large shielding codes that have come to dominate shielding design and analysis. An assumption is made that the reader has an understanding of mathematics through basic calculus and vector analysis as well as a knowledge of the nuclear physics of radioactive decay. For most chapters, problem sets are provided.

Book Description
The SCALE computational system is a modular code system for analyses of nuclear fuel facility and package designs. With the release of SCALE-PC Version 4.3, the radiation shielding analysis community now has the capability to execute the SCALE shielding analysis sequences contained in the control modules SAS1, SAS2, SAS3, and SAS4 on a MS- DOS personal computer (PC). In addition, SCALE-PC includes two new sequences, QADS and ORIGEN-ARP. The capabilities of each sequence are presented, along with example applications.

Book Description
In October 1978, a group of 41 scientists from 14 countries met in Erice, Sicily to attend the Second Course of the Interna tional School of Radiation Damage and Protection "Ettore Majorana", the proceedings of which are contained in this book. The countries represented at the School were: Brazil, Canada, Federal Republic of Germany, Finland, German Democratic Republic, Hungary, India, Italy, Japan, Spain, Sweden, Switzerland, United States of America, and Yugoslavia. The School was officially sponsored by the Italian Health Physics Association, the Italian Ministry of Public Education, the Italian Ministry of Scientific and Technological Research, and the Sicilian Regional Government. In addition, administrative and tech nical support was received from the Stanford Linear Accelerator Center and from CERN. The past 15 or so years have witnessed a significant develop ment of computer methods in the science of radiation protection. The radiation transport codes associated with hadronic and electro magnetic cascades, reactor shielding, unfolding techniques, and gamma ray spectrum analysis have reached the state-of-the-art level, and the Erice Course aimed at presenting as comprehensive an over view of these programs as was possible within the allotted time span.
