Abstract
A personnel electronic dosimeter includes a neutron-proton and neutron-alpha converter for providing an electrical signal having a magnitude proportional to the energy of a detected proton or alpha particle produced from the converter, a pulse generator circuit for generating a pulse having a duration controlled by the weighed effect of the amplitude of the electrical signal, an oscillator enabled by the pulse for generating a train of clock pulses for a time dependent upon the pulse length, a counter for counting the clock pulses, and an indicator for providing a direct reading and aural alarm when the count indicates that the wearer has been exposed to a selected level of neutron dose equivalent.
Claims4
A personnel electronic neutron dosimeter capable of being carried on the clothing of a user comprising:
- neutron detector means for producing secondary reactions which generate an electrical signal;
- pulse generator means, connected to said detector, for generating a pulse, the duration of each pulse being controlled by the amplitude of each electrical signal;
- oscillator means, enabled by said pulse generator, for generating clock pulses, thereby providing a dose equivalent representation;
- counter means for counting the clock pulses;
- and
- indicator means for providing a direct indication of accumulated radiation.
