Nuevo dosímetro de zona programable para la medición y monitoreo operacional de la radiación gamma externa

abstract the detection and measurement of nuclear radiation have turn into an important aspect in the application of nuclear detectors and specifically, the geiger muller tubes. endowed with high detection sensibility, robust construction and a relative simplicity of the associated circuit, the geiger tubes are still one of the most widely used detectors in all areas of application in physics and nuclear research. a new design of the instrument enables measurements of the environmental external dose rate of g (gamma) radiation from 0.05 μsv/h to 10 msv/h. it consists of three elements: geiger-muller detector, a data acquisition and control card and the application software. the instrument is connected to the computer through a usb interface only to vary and adjust the calibration parameters. the software was developed in c programming language using the picc4.08 compiler.
