Description
Disk Sources are mainly used for checking the performance of GM tubes and NaI detectors. The disks measure 1″ (25.4 mm) by 0.25″ (6.35 mm) and are manufactured of high-strength plastic. The active diameter of the disk is 0.197″ (5.0 mm) with the active area centered in the disk.
Capintec offers the highest quality disk source at the lowest cost (to you.) There are many more nuclide disk sources available than are shown. If you do not find the source you need, call Capintec; we will let you know what is available.
