This is a brand new radiation detector Dosimeter – Defender – the model of April 2012. The list of equipment from now includes rechargeable batteries, battery charging set and USB cable.
The new radiation dosimeter is quite compact and of a vivid yellow color. The high-quality case is rubber-plastic, nice to hold.
The new device has an up-to-date Geiger-Muller SBM 20-01, made in Russia.
Once into action, the Geiger counter shows the current radiation background. The measurement speed is high – once in 10 seconds. The radiation value is indicated not only in numbers but accompanied with textual descriptions, like “Normal Radiation Background”. Thus you won’t have to remember the hazardous- readings, all is shown.
Second screen indicates the accumulated radiation dose – this makes the Dosimeter Defender fundamentally different compared to its ancestors.
