A DISCUSSION OF THE BASIC PROBLEMS AND TECHNIQUES ENCOUNTERED IN X-RAY EXAMINATIONS OF PACKAGE CONTENTS.
Abstract
TERMINOLOGY, RADIATION STANDARDS, AND MEASUREMENT TECHNIQUES ARE DEFINED. TWO RECENT DEVELOPMENTS IN XRAY TECHNOLOGY ARE DISCUSSED TOGETHER WITH PHOTOGRAPHS OF EXPERIMENTAL APPLICATION. THE FIRST SYSTEM IS A STATE-OFTHE-ART DEVELOPMENT UTILIZING A 'FLYING SPOT' XRAY SOURCE IN CONJUNCTION WITH AN XRAY SCINTILLATION DETECTOR, WORKING AS A FIXED INSPECTION SYSTEM OF EXTREMELY LOW RADIATION LEVEL. SATISFACTORY OPERATION IS SHOWN AT A RADIATION LEVEL LOWER THAN 4 ORDERS OF MAGNITUDE BELOW THAT OF CONVENTIONAL CHEST XRAYS. THE SECOND SYSTEM INVOLVES THE USE OF CONVENTIONAL FLUOROSCOPIC INTENSIFIER TECHNIQUES TOGETHER WITH A LIGHT WEIGHT PORTABLE PULSED XRAY SOURCE, OPTIMIZED TO FORM A LOW LEVEL PORTABLE XRAY SYSTEM, OPERATING AT HIGHER DOSAGE LEVELS.
