Rapid detection and size determination of PuO sub 2 particles using a charged-particle imaging video monitor system
- Nagoya Univ. (Japan)
A charged-particle imaging video monitor system was constructed and applied to video imaging of the position profile of PuO{sub 2} particles on filter paper. The imaging video monitor system consists of a detector head, a silicon intensifier target (SIT) camera, a video frame memory, and a personal computer. The system can display the distribution image of PuO{sub 2} particles becoming gradually clearer on a video monitor. The integrated image that is transferred to the computer is analyzed quantitatively for the radioactivity of each PuO{sub 2} particle deposited on the filter paper. The system can not only rapidly distinguish PuO{sub 2} particle contamination from Rn daughter products, but can also determine the size distribution of the PuO{sub 2} particles.
