Floods

LEA produces and distributes Flood sources, Co-57 rectangular sources designed for rectangular FOV (field of view) gamma cameras to check the nominal settings and the uniformity of response of the system.

These sealed sources are at least classified C 22212 in accordance with ISO2019.

Flood sources are made of a shell (to ensure a secure seal) containing a resin in which the radionuclide is uniformly distributed. Flood sources have a percentage of differential nonuniformity ≤3% over the entire active surface of the source.

To facilitate the handling, some Flood sources could have a groove around the entire periphery, allowing easy handling.

Lead-protected mobile carry cases are also available to facilitate movement and storage of Flood sources.

LEA can also offer other Flood geometries:

• square, with a total dimensions of 11.5 x 11.5'' (29 x 29 cm) and an active surface area of 10 x 10'' (25 x 25 cm) for activities of 0.5 mCi (18.5 MBq), 3mCi (111 MBq), 10mCi (370MBq), 15 mCi (555MBq), 20mCi (740MBq).
• circular, with a total diameter of 20.3" (51.5 cm) and an active diameter of 18.5" (47 cm), for activities of 5mCi (185 MBq), 10 mCi (370MBq), 15mCi (555MBq).
