After the device is turned on, it starts evaluation of the radiation background. The first results are displayed in 9 seconds. To determine the background radiation emanated by a specific object, select "Measurement" mode, take SOEKS QUANTUM to the object, evaluate the result. The measurement results and the accumulated dose are saved in the dosimeter memory.
The minimum service life is 7 years. User-friendly and functional SOEKS Quantum dosimeter has been developed by SOEKS engineers, and is in demand all over the world. Sold in more than 40 countries.

SOEKS Quantum is a professional dosimeter that combines measurement accuracy, user-friendly interface and affordable price. Color and sound indication, measurement results recorded in device memory, the capability to move data to computer and update the software with "SOEKS Device Manager" program make device operation as comfortable as possible for both professionals and naive users. That is why Quantum has become the most popular professional dosimeter. It can be used by public services (state emergency services, customs), banks, nuclear power plants etc., and in everyday life (for checking home, construction materials, garden plot). If necessary the instrument can be calibrated in a specialized accredited laboratory.
