RADON-1M
The radiation indicator RADON-1M is a pocket device for the detection of α-, β-, γ-radiation.
The radiation indicator is a battery operated device designed for the detection of α-, β-, γ-radiation in the rooms, canalization wells, in the open air etc.
The detection of the radiation is followed either by the peeps of the buzzer or by the reading of the indicator on the upper top panel of the device. The radiation level is easy to follow by the frequency of the peeps of the buzzer. The peeps correspond to the counts. The higher is the frequency of the peeps the higher is the radiation level.
The location of the indicator pointer indicates the radiation level. At normal background level the indicator pointer lies at green area. At moderate radiation level the pointer moves to the yellow area. At high radiation level the pointer moves to the red area and in some cases out of the scale of the indicator. This means that the radiation level remarkably exceeds the normal value.
