Product Introduction

The NT6108-100 portable surface contamination measuring instrument adopts the scintillation detection method with ZnS coating, which can be fixed or moved for direct or indirect detection of surface contamination. It is mainly used to detect the degree of alpha or beta radioactive contamination on the surfaces of workbenches, floors, walls, hands, clothes, shoes, etc. in radioactive workplaces and laboratories. It is widely used in environmental protection, public security, military, customs, ports, health, nuclear industry, nuclear power plants and other systems. This instrument is a small portable instrument with LCD display. It uses pulse shape discrimination circuit and intelligent analysis algorithm to automatically distinguish alpha and beta particles, achieve simultaneous measurement of alpha and beta, and minimize their mutual influence.
