Claim 1
Independent Claim
153 words
IN A SYSTEM FOR DETECTING RADIATION CONTAMINANTS IN A REACTOR FACILITY COMPARTMENT WHICH COMPRISES A PUMP FOR PUMPING AN AIR SUPPLY WHICH MAY INCLUDE GAMMA AND BETA RADIATION PARTICLES FROM SAID REACTOR COMPARTMENT, A DETECTOR ADAPTED TO RECEIVE INCIDENT RADIATION IN SAID AIR SUPPLY, MEANS FOR COLLECTING SAID GAMMA AND BETA PARTICLES IN SAID AIR SUPPLY IN THE VICINITY OF SAID DETECTOR, SAID DETECTOR ADAPTED TO PRODUCE AN OUTPUT OF CORRESPONDING ELECTRICAL PULSE VARIATIONS IN RESPONSE TO VARIATIONS IN INCIDENT RADIATION, A SINGLE ABSORBER ELEMENT ADAPTED TO MODULATE PERIODICALLY SAID INCIDENT RADIATION TO ABSORB SAID BETA RADIATION CONTAMINANT AND TO PASS OTHER RADIATION ON TO SAID DECTOR, MEANS FOR ALTERNATELY CHANGING THE POLARITY OF SAID ELECTRICAL PULSES IN SYNCHRONISM WITH SAID MODULATING MEANS AND MEANS FOR INDICATING ANY DIFFERENCE IN SAID OUTPUT PULSES WHEREIN SAID DIFFERENCE INDICATES THE PRESENCE AND AMOUNT OF BETA CONTAMINANT IN SAID AIR SUPPLY WHILE SUBSTANTIALLY IGNORING OTHER RADIATIONS.
