Introduction to directional gamma radiometer:

Directional gamma radiometerIt is a new generation of microcomputer gamma directional radiometer with single tube and double crystal compensation type, which can measure the intensity of gamma radiation in one directional measurement. It is suitable for sampling gamma radiation in pure uranium deposits, tunnels, and surface exposure projects. It can also be used for environmental recording as mentioned above, and is also used in other occasions where different directions of gamma radiation need to be measured. The instrument adopts a microcomputer controlled digital circuit, Chinese LCD display, data storage, standard computer interface, and has the advantages of small size, light weight, simple operation, and lithium rechargeable battery. Sampling and recording of gamma radiation in uranium deposits, tunnels, and surface exposure projects can also be used to determine specific directions.
