Uncalibrated Solid Sources
Individual 1-Inch Sources
These uncalibrated sources are fabricated in the same manner as the
calibrated gamma sources, except in 1-inch diameter (25mm) by 1/4-inch
thick (6mm) plastic disks. These nominal activity sources are supplied
individually or as a set. Disk sources are identified as alpha, beta,
or gamma as shown in the adjacent example. Uncalibrated sources contain ±20%
of the stated activity and are routinely compared to calibrated reference
standards. These sources are offered in the standard activities listed
below. Custom sources of different activities and/or geometries will
be quoted on request.
