For the study of industrial X-ray, protection, a sensitive radiation integrating meter is required. The characteristic of the meter described, with the signal received in the third grid, is that the leakages in the first and second grids are reduced to minimum raising the sensitivity over 20 times of that of customary meters: 50μr is the full scale reading in the setting for the highest sensitivity when 350cm3 of air chamber is used. The circuit is stabilized because of the negative feed back; simplicity of the circuit makes the meter to be assembled small in size and portable.
