This process minimizes line broadening and produces sources exhibiting line widths <strong>typically<\/strong> less than 27 keV full width half maximum (FWHM). Sources containing Np-237 have line widths typically 50keV FWHM, due to the low specific activity of Np-237. Wipe test results comparable with sealed sources are achieved for this manufacturing process. However, any material placed over the active deposit will degrade the spectrum, so it is not possible to construct a source that can be classified as a sealed source as defined in ISO2919.\r\n\r\n<strong>Certification<\/strong>\r\n\r\nCalibrated single nuclide sources are supplied with a DAkkS certificate stating alpha particle emission rate and activity. Triple nuclide sources are designed for energy calibration applications.\r\n\r\n<strong>Uncertainties<\/strong>\r\n\r\nThe reported uncertainty is based on a standard uncertainty multiplied by a coverage factor k=2, providing a level of confidence of approximately 95%. The expanded uncertainty of the emission rate for a calibrated single nuclide source is =3 %.\r\n\r\n<strong>Traceability<\/strong>\r\n\r\nThe sources are traceable to standards held by national laboratories such as the Physikalisch-Technische Bundesanstalt (PTB, Germany), the National Physical Laboratory (NPL, UK), the National Institute of Standards and Technology (NIST, USA) the Laboratoire Primaire des Rayonnements Ionisants ( France), and many other national laboratories world-wide. Further details are given in the section General Technical Information.\r\n\r\n<strong>Recommendations on source handling<\/strong>\r\n\r\nTo maintain the accuracy of measurements, these sources must be handled with care. Sources should be handled with tweezers to avoid leaving grease on the surface of the source, which would degrade the spectrum. The sources must not be cleaned with abrasive compounds such as metal polish, as this would remove the active deposit. The sources should be kept in their storage boxes when not in use.\r\n\r\n<strong>Tolerances<\/strong>\r\n\r\nThe maximum deviation of the measured activity at the reference time from the nominal value is +\/-30%.\r\n\r\n<strong>Availability<\/strong>\r\n\r\nThe sources are normally delivered within 4-6 weeks from receipt of order.\r\n\r\n<strong>Quality assurance<\/strong>\r\n\r\nThe sources are calibrated at Eckert &amp; Ziegler Nuclitec GmbH\u2019s DAkkS accredited measurement laboratory in Germany. The manufacturing facility operates a quality management system which has been independently audited and approved to ISO9001:2008.","link":"","link2":"","file":"","btnausrichtung":"align-left","id":"","textrahmen":false,"twocoloum":false,"tableshort":false,"abstand_oben":true,"abstand_unten":true},{"acf_fc_layout":"modul_text","headline":"","headlinetype":"p","headlineclass":"p","text":"<table

These nuclides provide alpha particles from approximately 5100 to 5800 keV and exhibit line widths typically less than 20 keV FWHM. This energy range is wide enough to provide a valid energy calibration for most alpha emitting nuclides.\r\n\r\nThe source, when purchased as a NIST traceable standard, can also be used to determine detector efficiencies for alpha particles. Total activity and individual activities are provided on the Certificate of Calibration.\r\n\r\nThe composite alpha source is available in the type A-2, A-1 and PM configurations.\r\n\r\noption: window material: 100\u00b5g\/cm2 gold\r\n\r\n(15 keV FWHM increase, 15 keV energy decrease)\r\n\r\n&nbsp;","link":{"title":"Back to overview - Reference Sources","url":"https:\/\/www.ezag.com\/produkte\/isotope-products\/isotrak-calibration-sources\/reference-sources\/","target":""},"link2":"","file":"","btnausrichtung":"align-left","id":"","textrahmen":false,"twocoloum":false,"tableshort":false,"abstand_oben":true,"abstand_unten":false}],"thumb":"","kurzbeschreibung":""},"_links":{"self":[{"href":"https:\/\/www.ezag.com\/de\/wp-json\/wp\/v2\/pages\/161","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.ezag.com\/de\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/www.ezag.com\/de\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/www.ezag.com\/de\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.ezag.com\/de\/wp-json\/wp\/v2\/comments?post=161"}],"version-history":[{"count":44,"href":"https:\/\/www.ezag.com\/de\/wp-json\/wp\/v2\/pages\/161\/revisions"}],"predecessor-version":[{"id":10567,"href":"https:\/\/www.ezag.com\/de\/wp-json\/wp\/v2\/pages\/161\/revisions\/10567"}],"up":[{"embeddable":true,"href":"https:\/\/www.ezag.com\/de\/wp-json\/wp\/v2\/pages\/155"}],"wp:attachment":[{"href":"https:\/\/www.ezag.com\/de\/wp-json\/wp\/v2\/media?parent=161"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
