The window is divided into two independent display areas. The
upper one reflects DER, gamma radiation pulse count rate, and an
intensity histogram of gamma radiation reflecting pulses at each
10 ms during the last 28 s, and the bottom one – DER, neutrons pulse
count rate, and an intensity histogram of neutron radiation that shows
pulses at each 100 ms during the last 24 s. The resolution of display
of the pulse count rate of gamma radiation is 1 cps, that of neutrons –
0.01 cps. A unit of measurement is found near each value according
to which data is displayed at this point of time.
In the upper left corner of the histograms, there is a figure that
demonstrates the current dimension of the histogram, and each point
within its field on the vertical axis indicates the 1/10 of this value
(Fig. 6).
Note. In the absence of a neutron radiation source in the
environment, the intensity histogram of neutron radiation will not be
seen on the display since the common background radiation has no
neutron component.
