1.2.2 The dosimeter ensures automatic subtraction of gamma radiation
component during measurement of beta radiation parameters.
1.2.3 The dosimeter allows storing up to 1500 measurement results in the non-
volatile memory. For easier identification, each measurement result is recorded with
information about measurement time, geographical coordinates of measurement and
a reference three-digit number of measurement object, which is entered during
recording.
1.2.4 The dosimeter provides for automatic recording of photon-ionizing
radiation DE accumulation history in its nonvolatile memory. The nonvolatile
memory capacity ensures saving up to 2200 DE values. Saving frequency depends
on DER and falls within 10 to 1 minute. DE is saved additionally when you turn the
dosimeter on and off.
1.2.5 The dosimeter beeps at detection of every gamma quantum, alpha- or
beta-particle.
1.2.6 The dosimeter allows viewing measurement results earlier stored in the
nonvolatile memory on its own LCD, and PC communications via the
infrared port.
1.2.7 The dosimeter has an analog indicator of measured radiation intensity.
1.2.8 The dosimeter allows programming the values of threshold alarm for
each measured radiation parameter.
1.2.9 The dosimeter sends a light and a sound signal when the programmed
threshold levels are exceeded.
