New technique for measuring wind velocity

A new technique for measuring wind velocities of meteorological interest is described. It is based on inverse square law variation of the counting rates as the radioactive source‐to‐counter distance is changed by the movement of the source caused by the wind velocity. The technique is usable anywhere, for all noncorrosive media, except in places with no local gravitational force. Measurements reported herein indicate that the proposed technique may be quite suitable for measuring wind speeds in the range of 5–100 m/s, that are either steady, or, whose rates of fluctuation are less than 1 kHz.
