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 scanning throughout its length for uniformity.
The uniformity of the line sources is within +/- 5% limits.
