Automatic radioactive liquid sample measurement device

The invention provides an automatic radioactive liquid sample measurement device. A sampling device, a sampling tank, a collimator, a detector, a preamplifier, a main amplifier, a signal processor, a calibrator and a computer in the measurement device are sequentially connected with each other. A liquid inlet tube, a liquid outlet tube, a peristaltic pump and a liquid discharge tube in the sampling device are sequentially connected with each other; the liquid inlet tube and the liquid outlet tube are arrayed in parallel and are fixed on a sliding block of a lifting device; and the sample measurement time and measurement time interval of the measurement device can be adjusted, and the counting rate of continuously measuring a sample is displayed on a computer display screen in a graphical display mode. The automatic radioactive liquid sample measurement device can be used in a strong ionizing radiation environment, can realize automatic online radioactive liquid sample concentration measurement immediately, an
