Abstract

The purpose of this study is visualization of concealed light elements materials in metallic environments using a cooled CCD camera with an image intensifier. In this study, gamma-rays were used for visualization. As a gamma-ray source, radio-isotopes such as ⁵⁷Co, ¹³³Ba and ¹³⁷Cs were used. Gamma-rays penetrate through sample materials and are firstly enhanced by an image intensifier and then detected by a cooled CCD camera. Materials such as explosives or organic matters were observed through various metal plates.
