Abstract

The invention discloses a liquid scintillation counter which comprises a casing, wherein a functional area is arranged on the casing; an operation panel, a display screen and a miniprinter are arranged in the functional area; a control system, a power module, a photomultiplier tube and a sample moving device are arranged in the casing; a mounting groove is formed in the sample moving device and used for accommodating a sample bottle; the sample bottle is moved by the sample moving device to the middle of the photomultiplier tube for detection; the control system is used for power control as well as signal analysis and output; the power module is used for supplying power. The liquid scintillation counter is simple and skillful in structure, a sample is moved by the sample moving device to the photomultiplier tube for detection, a detection environment is guaranteed by means of an added sealing cover, the control system outputs a detection result to the internet or a printer, and convenience and fastness are realized.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a liquid scintillation counter. Background technique [0002] The liquid scintillation counter is an instrument suitable for measuring the activity of low-energy pure β radionuclides. For example, detect the weak radioactivity of hydrogen-3 and carbon-14. It has the advantages of high sensitivity, easy operation and strong applicability. It is composed of a transparent container with samples and liquid scintillator, a photoelectric pair lamp tube, and electronic instruments (including main amplifiers, discriminators, calibrators, etc.), and has a wide range of applications. The luminescent substance used for liquid scintillator is dissolved in an organic solution. It requires short luminous attenuation time, good transparency, easy preparation and low cost. A typical liquid scintillator is a toluene solution of 5g / L terphenyl and 0.5g / L POPOP, which is slightly blue and transp...
