Tungsten Radiation Shielding Application in Non-destructive Testing(NDT)

Non-destructive testing is a method or relevant means that usually been used without damaging the product structure, without compromising the performance of the product. The detection of products can be divided into two kinds, which included destructive products and non-destructive products, the latter focused on appearance, it means that should be tested one by one, but can be as long as qualified. For the former usually takes some samples, and focuses on the intrinsic quality of the designated products suspected inherent defects were dissected. Since the destructive testing will eventually be used at the cost of a product, so using non-destructive testing method to test products can balance that, i.e., it can certainty not destruct the product and handle the intrinsic quality of the product.

Non-destructive testing(NDT) methods may rely upon use electromagnetic radiation, sound and inherent properties of materials to examine samples, which includes examining the materials external surfaces in details by microscope. Although samples preparation techniques for matallographic, optical microscope and electron microscope are generally destructive as the surfaces must be made smooth through polishing or the samples must be electron transparent in thickness. Therefor the interior of samples can only be examined with penetrating electromagnetic radiation, such as X-rays or 3D X-rays. Therefor,Tungsten radiation shielding could be used effectively for radiation protection from the harm radiation when testing the defects of products by X-ray or 3D X-ray.
