Abstract
Abstract Apparatus for measuring a radiation source level by means of a detector such as a scintillator or the like, the apparatus having a signal channel for providing a source of signal pulses from the detector indicative of the radiation level to an output device, and a timer channel for preselecting a time period of signal pulse measurement. The detector output is coupled to a comparator biased for providing an output signal in response to an input indicative of an excess radiation pulse such as a cosmic energy overload, the output of the amplifier triggering a predetermined time delay for inhibiting the signal channel and timer channel for the time duration of the overload.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
106 words
In radiation source measuring apparatus having a signal channel transmitting signal pulses from a radiation source detector to an output device under control of a timer channel providing timing pulses indicative of a predetermined time period for measurement of the signal pulses, the combination comprising: means coupled to the output of said detector for providing a signal only in response to a detector output in excess of a predetermined level; and time delay means responsive to said signal for simultaneously inhibiting the timing pulses in said timing channel and the signal pulses in said signal channel for the predetermined time duration of said time delay means.
Claim 2
Dependent Claim
106 words
In radiation source measuring apparatus having a signal channel transmitting signal pulses from a radiation source detector to an output device under control of a timer channel providing timing pulses indicative of a predetermined time period for measurement of the signal pulses, the combination comprising: means coupled to the output of said detector for providing a signal only in response to a detector output in excess of a predetermined level; and time delay means responsive to said signal for simultaneously inhibiting the timing pulses in said timing channel and the signal pulses in said signal channel for the predetermined time duration of said time delay means.
Claim 3
Dependent Claim
44 words
The combination according to claim 1 wherein the radiation source measuring apparatus includes a signal scaler in the signal channel receiving signal pulses from a signal gate through normally enabled gate means, said gate means being disabled in response to said time delay means.
Claim 4
Dependent Claim
55 words
The combination according to claim 2 wherein the radiation source measuring apparatus includes a timer scaler in the timer channel receiving timing pulses from a timer gate which receives timing pulses from a timer base means through normally enabled second gate means, said second gate means being disabled in response to said time delay means.
Claim 5
Dependent Claim
27 words
The combination according To claim 3 wherein said time delay means is a one-shot multivibrator having the output thereof coupled to said first and second gate means.
Claim 6
Dependent Claim
24 words
The combination according to claim 4 wherein said means coupled to the detector output is a comparator providing a signal to said multivibrator input.
