Alpha Spectrometry System

Alpha Spectrometry System Schematic Diagram

The alpha spectrometry system is used to measure the activity of an alpha-emitting radionuclide, Plutonium-239.

Since alpha particles are readily absorbed in air, they are measured in vacuum to prevent any interaction with the air before it reaches the detector. Therefore, all 8 detectors of the system are housed inside a vacuum chamber. The digitized signals of the detectors are stored as energy spectra for quantitative analysis using a special software. The system can measure 8 samples simultaneously, hence providing a high throughput.
