Determining the Thickness of Material Using the Transmission Method of Beta Particles
Main Article Content
Abstract
Currently, the use of radiation in industry is very popular in Vietnam. The applications of beta, low energy gamma or X-ray radiation are used to measure and control product thickness such as paper, plastic film, aluminum foil, steel, thin film in industry, etc. We have carried out researches, calculations, experiments and gave calibration equations for the system to measure the thickness of small Z-coefficient materials (aluminum, silicon, ...) with a thickness from 0.1 mm to 3 mm using transmission method of beta radiation.
Keywords
radiation equipment, checking material thickness, materials with small Z, beta particles
