But niobium is the last element reliably identified by conventional X-ray fluorescence analysis. A radically different situation is observed when the X-ray radiometric modification of energy dispersive X-ray fluorescence method is used, in which the sample is excited by a high-energy radioisotope source Am-241 rather then by X-ray tube radiation. An advantage of this method is that the K-lines of heavy metals are actively excited and are not overlapped by the lines of macro-elements.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9786139922789\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9786139922789","offer_id":39447466999901,"sku":"9786139922789","price":48.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/69eba4ea-ed7b-40f2-a74d-2c62bb022096.jpg?v=1776408870","url":"https:\/\/shop.autorenwelt.de\/products\/soil-contamination-by-heavy-metals-von-yury-vodyanitskii-aleksandr-savichev","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
