The principle of this unit is to make use of the ability of radioactive radiation to penetrate through the metal.\u00a0The unit consists of the radioactive source, which is one of the radioactive isotopes (Cs-137). It is located in a lead shield coordinated with a collimating system and detector. The sample wanted to be tested takes the shape of a metal rod and is placed on a moveable stage motivated by a stepper motor, which enable it to move in a limited time, and the rod is located between the source and detector.<\/p>\n<p style=\"text-align: justify\">The intensity of penetrating radiation in the defected rod is recorded by a longitude scan of the rod. The results are recorded by the computer, which is connected to the detector through an electronic interface.\u00a0By using specialized software; a curve, which represents the relationship between the length of the rod and the radiation intensity, is given. This curve indicates the cracks, cavities and defect found in the rod and its locations. The curve shows high peaks in the defected areas and low peaks in the locations of non-homogeneous area.\u00a0The preliminary experiment for the operation of this system has reveled its easy usage with good speed and efficiency for testing in comparison with traditional methods such as \u00a0x-ray regarding such method has never been used before.<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Inventor:\u00a0Prof. Dr. Samir Khudhur Yaseen\/Department of\u00a0physics &#8211; College of Science for women &#8211; University of Baghdad Abstract In this practical &#8230; <\/p>\n","protected":false},"author":5,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_lmt_disableupdate":"","_lmt_disable":"","footnotes":"","_links_to":"","_links_to_target":""},"categories":[6],"tags":[],"class_list":["post-19901","post","type-post","status-publish","format-standard","hentry","category-Patents"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v25.8 -
