| 摘要 |
The invention relates to a device for measuring gamma activity of a radioactive liquid characterised in that it comprises - a gamma activity detector 1, - a vertical tube 3, placed in front of the measurement window of the detector, - means 6 for making a central jet 7 of sample liquid flow coaxially with this tube, - means 11, 12, 13 for making a film of liquid for entraining possible projections produced by this sample jet flow along the internal walls of the tube, and - means 9 for blowing, into the internal volume of the tube, a gas for sweeping the gaseous or volatile radioactive product entrained or released by the liquid sample. In this manner, it is possible to make a real-time and continuous measurement of the gamma activity of the sample liquid. <IMAGE>
