RAM-Ⅰ type x γ radiation alarming device (nationwide bag installation)
RAM-type I (desktop) radiation alarming device is a new type of fixed installation in the rays of the lab computer room, irradiation/x γ radiation dose online and continuous monitoring alarm device, it adopts the special design the preamplifier and silicon detector (other detector be according to radiation level choice), has a high sensitivity, convenient operation, automatic display, data storage and super threshold alarm and other characteristics, can real-time x γ radiation dose rate are (μ Gy/h and μ Sv/h can convert display), at the same time, you can give the individual cumulated dose (μ Sv), but also can be used as online radiation monitoring system to realizes real-time monitoring and super threshold safety alarm.
Instrument by the semiconductor or GM or scintillation detectors (according to ray high and low choose pipe), power supply circuit, count display and operation panel, put ZhuFang circuit, and before the alarm lamp components. Probe the shaping circuit with 15 meters cables and host connection, the host the frequency, time counting, points alarm circuits, etc, realize the dose rate measure and report to the police. The measuring time timing fast gear 3 seconds, a low gear timing 3-60 seconds, can according to dose rate size selection. Panel key can be in 0.25 u Gy/h-10 Gy/h set threshold between, when dose rate exceeds the threshold value, the instrument lighting and sound alarm and happen automatically record store, can find out the historical record inquires threshold alarm value. It is widely used in radioactive waste repository, industrial NDT, hospital γ knife therapy, isotope application of gamma irradiation, hospital, X-ray diagnosis, treatment, nuclear power station cobalt radioactive place, remind staff or radiation equipment is already in radioactive sources work or leak state, make its from radiation hazards. According to ray device, in the threshold alarm at the same time, according to the special requirements of users need to design door control signal to realize "door machine chain" function.
