Imaging of heavily shielded sources
Categories / Use case By Sogdiana Faiazova
With our Compton Camera, thanks to it’s high spatial resolution and good signal/noise ratio, it is possible to image heavily shielded sources.
In this case we are observing a high activity (1GBq) ¹³⁷Cs source used for level gauging.
The source is shielded by 20 cm of lead.
- In 10 minutes using the 80 photons on a total 20.000 selected on the ¹³⁷Cs peak (662 +/- 30 keV), it is possible to locate the source correctly through shielding.
- Then on the same acquisition, using the diffused photons, it is possible to image the hole in the shielding used for level gauging when the source is active.
