For the law enforcement officer and the civilian who may be in a situation that requires the use of a handgun to stop a lethal threat action, it is important that the person differentiates between the crass, glib and self-serving advertisements of ammunition vendors and the reality of how, what and why effective stopping power occurs. Factors to consider are the physiological response, the psychological response, the time frame parameter and bullet efficacy. Of these four factors, only bullet efficacy can be somewhat controlled by the person, this only by understanding how and to what extent the bullet contributes to the degree of stopping power obtained. A number of concepts / formulae have been included so as to permit the reader to consider their merits and whether or not they are consistent with the reality of biology, physics and other relevant sciences. Finally the material in this book is intended to permit those persons to instruct, teach or make decisions regarding the selection of a service handgun/cartridge combination that will help to provide the means to prevail in a lethal threat confrontation. About the Author: Mr. Bredsten retired from the Federal Law Enforcement Training Center/Firearms Division (FLETC/FAD). With FLETC/FAD he performed duties as a firearms instructor and he also taught ballistics to the FLETC/FAD staff and to students in the Law Enforcement Rifle Training Program and in the Precision Rifle (Sniper) and Observer Program. Subjects covered included the ballistic coefficient, barrel time, the coefficient of reduction (form), Greenhill formula (rate of rifling twist), firearm recoil, bullet time-of-flight, bullet drop, bullet midrange, wind deflection, bullet penetration potential and bullet terminal (wounding) efficacy. Since retiring he has provided ballistics consultation service for the FLETC/FAD, the Transportation Security Agency, the Orange County (Florida) Sheriff's Department and Exxon Mobil Corporation. Mr. Bredsten attended and completed various classes/courses relating to firearms (e.g., H&K MP5, Steyr Aug, Uzi, Tactical Speed Shooting and advanced shotgun) and ballistics (e.g., the first and second International Wound Ballistics Conferences, a Federal Law Enforcement Ammunition and Ballistics Seminar and Oehler's Ballistic Instrumentation). Mr. Bredsten has an AA degree from Chaffey Jr. College and a BA degree from Sacramento State College and currently resides in Georgia.

This text bridges the gap between introductory physics and its application to the life sciences. It is intended for advanced undergraduates and beginning graduate students. The Fourth Edition is updated to include new findings, discussion of stochastic processes and expanded coverage of anatomy and biology. The text includes many problems to test the student's understanding, and chapters include useful bibliographies for further reading. Its minimal prerequisites and wide coverage make it ideal for self-study. The fourth edition is updated throughout to reflect new developments.

A straightforward presentation of the broad concepts underlying radiological physics and radiation dosimetry for the graduate-level student. Covers photon and neutron attenuation, radiation and charged particle equilibrium, interactions of photons and charged particles with matter, radiotherapy dosimetry, as well as photographic, calorimetric, chemical, and thermoluminescence dosimetry. Includes many new derivations, such as Kramers X-ray spectrum, as well as topics that have not been thoroughly analyzed in other texts, such as broad-beam attenuation and geometrics, and the reciprocity theorem. Subjects are layed out in a logical sequence, making the topics easier for students to follow. Supplemented with numerous diagrams and tables.

Dr. Khan's classic textbook on radiation oncology physics is now in its thoroughly revised and updated Fourth Edition. It provides the entire radiation therapy team—radiation oncologists, medical physicists, dosimetrists, and radiation therapists—with a thorough understanding of the physics and practical clinical applications of advanced radiation therapy technologies, including 3D-CRT, stereotactic radiotherapy, HDR, IMRT, IGRT, and proton beam therapy. These technologies are discussed along with the physical concepts underlying treatment planning, treatment delivery, and dosimetry. This Fourth Edition includes brand-new chapters on image-guided radiation therapy (IGRT) and proton beam therapy. Other chapters have been revised to incorporate the most recent developments in the field. This edition also features more than 100 full-color illustrations throughout. A companion Website will offer the fully searchable text and an image bank.

From background physics and biological models to the latest imaging and treatment modalities, the Handbook of Radiotherapy Physics: Theory and Practice covers all theoretical and practical aspects of radiotherapy physics. In this comprehensive reference, each part focuses on a major area of radiotherapy, beginning with an introduction by the
