Abstract :
The objective of the research discussed is to design and develop a microcontroller-based multichannel analyzer (MCA) with a data reduction assembly (DRA) for a plutonium continuous air monitor (CAM) system. The MCA is capable of detecting the airborne alpha emitters in the presence of radon daughter products. The pulse output from the preamplifier has been stretched to allow the peak detector sufficient time to capture the pulse height. The pulse amplitude conversion, the data acquisition, and the output functions are carried out fully by software. The DRA consists of a data reduction unit (DRU) and its operator interface panel. The data reduction assembly has the ability to be networked to a single PC with up to 32 different CAMs remotely connected to it
