The DCS-1 instrument provides continuous precise measurements on drill cores or other soil and rock samples placed in plastic measuring trays. Magnetic susceptibility and dose rate of gamma-ray are  measured simultaneously in 1 cm steps along 1 m long samples. After continuous scanning the spectral   measurement with consequent analysis of K, U, Th concentrations on chosen parts of samples is available.

The DCS-1 instrument is equipped with automatic correction for background levels of both magnetic susceptibility and gamma-ray. The device is calibrated on artificial standards for 36 mm and 100 mm diameters of drill cores (other diameters can be agreed as well). K, U, Th assays are based on the use of 512 channel gamma-ray spectrometer with quantitative spectral analysis. The precise movement and positioning of the measuring head over the sample is performed with the use of the stepping motor.

The DCS-1 is designed for geological laboratory survey (scanning of rock samples), where it can save significant part of the working time and provide such a high quality of the measurement that cannot be reached using handheld instruments. The device is controlled from a user's PC. The measured curves of magnetic susceptibility and dose rate are shown currently on the computer screen.

Measured results are organized in the form of MS Excel files.
