Abstract : A counting-rate meter is described which provides for the operation of a pen writing device so that a continuous and permanent record of radiation intensity can be obtained. A control of the 'averaging time' or electrical damping is provided, so that the time necessary for the instrument to reach equilibrium need be no longer than that required for the desired statistical accuracy. This control is calibrated in terms of the statistical probable error in any given instantaneous indication. The instrument also contains a limit device which may be used to operate an alarm system.
