Abstract
WRITTEN FOR POLICE OFFICERS, FORENSIC SCIENTISTS, PATHOLOGISTS AND RADIOGRAPHERS, THIS BOOK INTRODUCES INCREASING APPLICATIONS OF X-RAY TECHNOLOGY IN THE FIELD OF FORENSIC INVESTIGATION. BEGINNING WITH A BRIEF DESCRIPTION OF THE HISTORY AND CHARACTERISTICS OF X-RAYS, THE AUTHOR, AN EXPERT RADIOGRAPHY CONSULTANT TO THE GLASGOW (SCOTLAND) POLICE, EXPLAINS THE THEORY OF X-RADIATION. HE DISCUSSES THE MOST COMMONLY KNOWN FORM OF RADIOGRAPHY AS WELL AS THE MORE SPECIALIZED FORM OF ELECTRONOGRAPHY, BY WHICH METALLIC ELEMENTS CAN BE MADE TO PRODUCE A RECORDABLE EMISSION WHEN IRRADIATED BY A HIGH KILOVOLTAGE X-RAY BEAM. SPECIFIC TECHNIQUES OF RADIOGRAPHY AND ELECTRONOGRAPHY ARE DISCUSSED IN FOUR MAJOR AREAS OF INVESTIGATIVE APPLICATION - FINGERPRINT RECOVERY FROM NON-HUMAN SURFACES, FINGERPRINT RECOVERY FROM HUMAN SKIN, MEDICAL DIAGNOSIS AND IDENTIFICATION, AND DOCUMENT EXAMINATION. THE USE OF GRENZ RAYS - LONGWAVE X-RAYS - IN DETECTING SUCH THINGS AS COUNTERFEITS, FINGERPRINTS AND GUNPOWDER PATTERNS, ARE ALSO EXAMINED. SEPARATE CHAPTERS DESCRIBE IODINE-125 AS A RADIOACTIVE SOURCE FOR PORTABLE X-RAY EQUIPMENT AND METHODS OF PROTECTION FROM THE HARMFUL EFFECTS OF X-RAYS. NUMEROUS DIAGRAMS AND PHOTOGRAPHS ARE INCLUDED TO ILLUSTRATE POINTS OF BOTH THEORY AND PROCEDURE. (SNI ABSTRACT)
