Instrument features:

♥This ray alarm instrument is an intelligent small radiation monitoring instrument, mainly used to monitor χ rays and γ rays, the instrument has low power consumption, high sensitivity, stable performance, simple operation, small size, can be worn and suitable for Put it in your pocket. At the same time, it adopts new single-chip technology, which has strong anti-interference ability and can work in harsh environments.

Working principle:

♥Under the irradiation of χ and γ rays, the detector outputs a sequence of pulses, the number of pulses corresponds to the dose rate of γ rays, and after input shaping, a standard pulse of a certain amplitude is formed and sent to the single-chip microcomputer, and the single-chip computer completes all digital processing function.

Functional application:

♥The radiation alarm device can prevent radiation workers from being infringed, and can effectively detect whether there is radiation in the surrounding environment. It is widely used in radiation monitoring in the fields of χ and γ-ray nondestructive testing, nuclear power plants, nuclear submarines, isotope applications, χ-ray diagnosis and accelerator and cobalt source therapy.

♥Radiation alarms are widely used in non-destructive testing, nuclear power plants, nuclear submarines, isotope applications, and hospital cobalt therapy.
