Continuous Long-term Measurement

Continuous measurement of ambient dose-equivalent rate (Ḣ*(10)) from 50 nSv/h to 10 Sv/h.

Hold the device steady at the point; wait for the reading to stabilise (~2 s at higher dose rates).

Measures dose rate and time of short-term exposure (from 0.03 s), 5 µSv/h – 10 Sv/h.

Select the short-term mode; the device automatically assesses exposure time and dose rate.

AT1123-specific: average dose-rate measurement of pulsed radiation with duration from 10 ns.

Near a pulsed source select impulse mode; measurement error can reach ±30% in this mode.

Detection of soft and hard gamma and beta sources, and locating moving sources.

The audio tone speeds up with count rate; sweep slowly to locate the source.
