The Bleeper III is a simple and reliable means of safeguarding all personnel against the hazards of ionising radiation by providing a clear, audible indication of X and Gamma radiation (without digital readout) The Bleeper III operates continuously, giving a bleep at approximately 15 minute intervals in normal background radiation. The bleep rate increases with doserate becoming a continuous tone in high radiation fields. A clear audible indication that the batteries need replacing is a change in the bleep length from one tenth of a second to one full second. Typical operating life using standard batteries is more than one year. As a further safeguard the correct functioning of the instrument is indicated at all times by a quiet series of ‘clicks’ easily heard by holding the loudspeaker to the ear.
