It is applicable to nuclides that emit alpha particles with energies above 3.9 MeV and at activity levels above 0.02 Bq\/mL (540 pCi\/L) of radioactive homogeneous water. This test method is not applicable to samples containing alpha-emitting radionuclides that are volatile under conditions of the analysis.<\/p>\n<p>1.2 This test method can be used for either absolute or relative determinations. In tracer work, the results may be expressed by comparison with a standard that is defined to be 100 %. For radioassay, data may be expressed in terms of alpha disintegration rates after calibration with a suitable standard. General information on radioactivity and measurement of radiation has been published and summarized in Practice D 3648.<\/p>\n<p>1.3 <i>This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.<\/i><\/p>\n<p><strong>Keywords<\/strong><\/p>\n<p>gross alpha radioactivity; gross radioactivity measurement; proportional counter; water<\/p>\n<p><strong>ICS Code<\/strong><\/p>\n<p>ICS Number Code n\/a<\/p>\n<p><strong>DOI:<\/strong> 10.1520\/D1943-05<\/p>\n<\/div>\n<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 \/> Terminology <br \/> Summary of Test Method <br \/> Significance and Use  <\/td>\n<\/tr>\n<tr>\n<td><b>2<b><\/td>\n<td>Measurement Variables <br \/> Interferences <br \/> Apparatus <br \/> Reagents  <\/td>\n<\/tr>\n<tr>\n<td><b>3<b><\/td>\n<td>Sampling <br \/> Establishing Gas Proportional Counter Operating Plateau <br \/> Control of Instrument Operation <br \/> Calibration and Standardization for General Measurements <br \/> Calibration and Standardization for Tracer Experiments <br \/> Procedure  <\/td>\n<\/tr>\n<tr>\n<td><b>4<b><\/td>\n<td>Calculation <br \/> Precision and Bias <br \/> Quality Control <br \/> TABLE 1  <\/td>\n<\/tr>\n<tr>\n<td><b>5<b><\/td>\n<td>Keywords  <\/td>\n<\/tr>\n<\/table>\n","protected":false},"excerpt":{"rendered":"<p><b>D1943-05 Standard Test Method for Alpha Particle Radioactivity of Water<\/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>2005<\/td>\n<td>5<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"featured_media":151816,"template":"","meta":{"rank_math_lock_modified_date":false,"ep_exclude_from_search":false},"product_cat":[2637],"product_tag":[],"class_list":{"0":"post-151810","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-astm","8":"first","9":"instock","10":"sold-individually","11":"shipping-taxable","12":"purchasable","13":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product\/151810","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\/151816"}],"wp:attachment":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media?parent=151810"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_cat?post=151810"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_tag?post=151810"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
