Determining the Thickness of Material Using the Transmission Method of Beta Particles

Authors: Mai Đình Thủy*, Bùi Ngọc Hà


Currently, the use of radiation in industry is very popular in Vietnam. In particular, there are applications of beta, low energy gamma or X-ray radiation to measure and control product thickness such as paper, plastic film, aluminum foil, steel, thin film in industry, etc. However, most of the equipment, the system of checking material thickness in Vietnam today are mainly imported from foreign countries with relatively high prices. Therefore, the demand for localization of automatic thickness gauges by charging sources is very much in the industry. The paper presents research results, builds the method and gives standard equations for measuring the thickness of materials with small Z numbers (aluminum, paper, silicon, ...) using the transmission method of beta radiation.
