Description
Overview
The GAO Tek gamma-ray radiation meter is specially designed to measure x,y radiation doses or rates in all kinds of radioactive working areas. In comparison with similar meters in China. This meter has a wider measuring range of dose rates. It has been widely used in hygiene departments, environmental protection, metallurgy, petroleum, chemical industry, radioactive laboratories, commodity inspection, etc.
