NUCLEAR TEST EQUIPMENT

THE CONCLUSIONS ARE: (1) NO RADIATION HAZARD EXISTS WHEN THE NUCLEAR GAUGES ARE PROPERLY HANDLED. (2) BEFORE USING NUCLEAR TESTING EQUIPMENT AN OPERATOR SHOULD RECEIVE INSTRUCTIONS ON THEORY, RADIATION, HEALTH SAFETY, MAINTENANCE, TESTING PROCEDURES, AND CALIBRATION. (3) STATISTICAL ANALYSIS OF THE DATA INDICATES THAT THE VARIANCE IN COUNT RATE ERROR IS BETTER DEFINED AS THE LENGTH OF TEST IS INCREASED. (4) CORRELATION CURVES DEVELOPED DURING THIS STUDY DO NOT AGREE WITH THOSE SUPPLIED BY THE MANUFACTURER, AND THE DEGREE OF CORRELATION IS IMPROVED WHEN A CURVE IS DEVELOPED FOR EACH TYPE OF MATERIAL TESTED. (5) THE STANDARD ERROR OF ESTIMATE FOR THE NUCLEAR TEST COMPARES FAVORABLY WITH THAT FOR THE VOLUMEASURE TEST IF AT LEAST A FOUR MINUTE COUNT RATE IS USED AND (6) NUCLEAR TESTING IS AN ACCEPTABLE MEANS OF CONSTRUCTION CONTROL, HOWEVER, PRESENT SPECIFICATIONS SHOULD BE REVISED TO COINCIDE WITH THIS CONCEPT OF TESTING. /AUTHOR/
