METHOD OF MEASURING STREAM OF IONISING RADIATION OF SINGLE SOURCE Russian patent published in 2010 - IPC G01T1/00 

FIELD: physics.

SUBSTANCE: method involves measuring a stream of gamm-rays of a single source by recording time distribution of separate gamma quanta and then summing them into time intervals - Δt_k, on which duration of the process taking place T=m·Δt_k, (where m is number of intervals, m≥1) is broken and constructing a histogram of the stream. Distribution of gamma quanta is recorded simultaneously with N independent identical detectors (where N≥1), lying in the same plane with uniform flux density in form of time marks of output current pulses. Time marks of output current pulses from all detectors are summed up in each of the intervals Δt_k and a histogram of the stream is constructed with time resolution τ_f≤Δt_k<<τ₀, where τ₀ is resolution of one channel, and t_f is duration of the front of the pulse. Sensitivity of measurements increases with increase in the number of detectors used, with preservation of the time resolution of measurements, equal to Δt_k.

EFFECT: measurement of a single stream Φ_γ(t) with time resolution higher than integral.
