Instrumentation laboratory is located at AMD, HQ, Hyderabad and is engaged in design, development and fabrication of instruments required for exploration activities. A full-fledged workshop supports these activities. The instruments designed, developed and fabricated are:

Borehole Logging Instruments

Gamma-ray borehole logging system for the natural gamma measurement consisting of detector {GM tube/NaI(Tl)}, armoured cable winch and a digital count rate meter.

Advanced count rate meter (ADCRM) is a data acquisition system used to carry out gamma ray logging of Bore holes using both Scintillation probe & GM probe and shielded probe.

Shielded probe Interface unit along with ADCRM & Shielded probe is used to carry out gamma ray logging of mine faces, trenches and active faces in the field.

Survey Instruments

Radiation Survey Meter:Radiation survey meter (RSM) with microcontroller based data acquisition, 1”x2” NaI(Tl) detector assembly, GPS, mass storage interface for measuring gross radioactivity along with data on coordinate, date, time and temperature.

Four Channel Differential Gamma-Ray Spectrometer: Microcontroller based four single channel analyser consisting of NaI(Tl) scintillation detector assembly for in-situ estimation of radio elemental concentrations.The unit displays the radio elemental concentration along with the count rates for U, Th and K.

MCA based Portable Gamma-Ray Spectrometer:Microcontroller based portable 256 channel multichannel analyzer (MCA) consisting of scintillation detector integral assembly of 3”x3” NaI (Tl), 256 channel MCA, GPS, storage media interface for in-situ estimation of radio elemental concentrations of U, Th and K.

Laboratory Instruments

Advanced core analysis system:The system is deployed for the evaluation of the grade (eU3O8). It is a 32 bit microcontroller based with inbuilt six channels to count the gamma pulses from the six GM tubes housed in brass enclosure and lead shielded to minimize the background effect.The grade value is evaluated by the inbuilt software and displayed in the seven inch capacitive touch panel

Radiometric analysis system:The system is portable, battery operatable and used for radioactivity measurement (eU3O8) of the borehole core and powder samples. It is a 32 bit microcontroller based system. The grade value is evaluated by the inbuilt softwareand parameters settings are done through the seven inch capacitive touch panel.

Radiation counting system:The system is used as a beta counting system used along with Gamma measuring instruments in the beta gamma method.The inbuilt high voltage is software programmable and Auto Plateau function is used to set appropriate HV to GM tubes.

PC based beta-gamma and gamma-ray spectrometric (MCA) systems:PC based beta-gamma and gamma–ray spectrometric {Digital Signal Processing based multi channel analyzer (MCA)} system for the measurement of eU3O8 and U3O8 of radioactive powder samples and radio elemental concentrations.

High voltage measuring meter (HVMM):HVMM is a controller based high voltage measuring instrument which measures the high voltage without loading the source due to its high impedance of the order of 2 Giga ohms. This is very useful to measure the HV more accurately in low current HV generating circuitries.

Bulk Uranium Ore Analyzer (BUOA):Bulk Uranium Ore Analyser (BUOA) is used to determine the grade of the run of uranium mine ore. The in-built software evaluates the grade of the run of mine and provides an audio-visual indication to delineate the ore grade for dumping the ore in appropriate stack piles.

Moisture Proof Digital Count rate meter (MDCRM)MDCRM is a moisture proof data acquisition system to carry out gamma ray logging of Bore holes and Shielded probe logging of mine faces, trenches and active faces in the field.
