Line Sources

Na-22 line sources are double layered tubes and made of high quality stainless steel. Each line source is sealed on its ends by the process of precise argon welding. Thanks to the argon welding process, the possibility of activity leakage is eliminated, ensuring safe use of line sources.

Uniformity

Each line source is tested with 5 mm steps of scannings throughout its length for uniformity.

The uniformity of the line sources is within +/- 5% limits.

SPOT SOURCES

Na-22 point sources are in two different forms; glass filled teflon capsule and acrylic disc.

Epoxy marked active area is located in the center of the point source with the dimension of 1 mm x 1 mm (0.039″x 0.039″) Overall dimensions far glass filled teflon capsule and acrylic disc type point sources are 25.4 mm x 6.35 mm (1″ x 0.25″) and 25.4 mm x 5 mm (1″x 0.20″) respectively.
