The values are determined from a knowledge of the atomic weight of elements and the thermal neutron absorption cross section in barns. This practice is illustrated by using the EBC factors of Table 1 which are based on thermal neutron (2200 m\/s) absorption cross sections. Other EBC factors may be used depending upon the actual neutron energy characteristics of the applicable reactor system.<\/p>\n<p>1.2 The following elements do not require to be included in the EBC calculations, as their EBC factors are less than or equal to 0.0001: aluminum; fluorine; rubidium; barium; lead; silicon; beryllium; neon; tin; bismuth; oxygen; zirconium; carbon; magnesium; cerium; phosphorus. Their contribution to the total poison effect is not considered significant. <\/p>\n<p>\n","protected":false},"excerpt":{"rendered":"<p><b>C1233-03 Standard Practice for Determining Equivalent Boron Contents of Nuclear Materials<\/b><\/p>\n<table class=\"shortdes-table\" style=\"width: 100%\" border=\"0\" cellspacing=\"0\" cellpadding=\"0\">\n<tbody>\n<tr>\n<td>Published By<\/td>\n<td>Publication Date<\/td>\n<td>Number of Pages<\/td>\n<\/tr>\n<tr>\n<td><a href=\"https:\/\/pdfstandards.shop\/product-category\/publishers\/astm\/\"><b>ASTM<\/b><\/a><\/td>\n<td>2003<\/td>\n<td>3<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"featured_media":48024,"template":"","meta":{"rank_math_lock_modified_date":false,"ep_exclude_from_search":false},"product_cat":[464,2637],"product_tag":[],"class_list":{"0":"post-48023","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-27-120-30","7":"product_cat-astm","9":"first","10":"instock","11":"sold-individually","12":"shipping-taxable","13":"purchasable","14":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product\/48023","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media\/48024"}],"wp:attachment":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media?parent=48023"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_cat?post=48023"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_tag?post=48023"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
