Detection and measurement of radiation : gamma rays, beta and alpha particles

الملخص EN

In this work we will introduce the various ways and means of detecting and measuring ionizing radiation, through its interaction attributes with the material of the detector that will be used, also the type of detector generally is chosen due the type of the radiation for example for the radiation consist of beam of photons it is better to use semiconductor detectors and for alpha or beta we can use the Geiger- Muller counter even for low energies.

This work is focusing into detection and measurement of gamma rays, beta and alpha particles.

In all cases, the passage of an ionizing radiation through the detector results in energy dissipation through a burst of ionization.

This burst of ionization is converted into an electrical pulse that actuates a readout device, such as a scalar or a rate-meter, to register a count.

It is necessary to understand the nature of radioactivity and how the detectors work and the role of each component of detection system involved.

Also we will see there are several factors affecting the measurement result of ionizing radiation detection of gamma rays, beta and alpha particles in this experiment.(keywords)
