The technique is based upon analysis of a neutron radiographic image and is independent of measurements and calculations based on physical dimensions of the collimator system. The values derived by this technique should be more accurate than those based on physical measurements, particularly for poorly defined apertures.<\/p>\n<p><h4>PDF Catalog<\/h4>\n<table border=\"1px\" class=\"des-table\">\n<tr>\n<th>PDF Pages<\/th>\n<th>PDF Title<\/th>\n<\/tr>\n<tr>\n<td><b>1<b><\/td>\n<td>Scope <br \/> Referenced Documents <br \/> Summary of Test Method <br \/> Significance and Use <br \/> Apparatus <br \/> Procedure  <\/td>\n<\/tr>\n<tr>\n<td><b>2<b><\/td>\n<td>FIG. 1   <\/td>\n<\/tr>\n<tr>\n<td><b>3<b><\/td>\n<td>Data Analysis  <\/td>\n<\/tr>\n<tr>\n<td><b>4<b><\/td>\n<td>FIG. 3   <\/td>\n<\/tr>\n<tr>\n<td><b>5<b><\/td>\n<td>Keywords <br \/> FIG. 4  <br \/> FIG. 5   <\/td>\n<\/tr>\n<tr>\n<td><b>6<b><\/td>\n<td>X1.
