other size Hard sapphire crystal bar

Product Description

The crystals intended for use as TLD are grown in the form of calibrated rods by the Stepanov method in a strongly reducing medium. The rods are then cut into 1-mm-thick tablets with a diameter of 5 mm, after which their own background is measured. To make a set of detectors with a preset spread of sensitivity values, this testing should be preceded by irradiation with a known dose. The corresponding data are entered into a computer and, if necessary, displayed; the accumulated doses are registered by a thermoluminescent analyzer.
