Application
OSGI-P sources are used for efficiency and energy calibration of gamma-spectrometric equipment, testing of ionizing chambers and scintillation counters. Robust design is suitable for “in field” calibrations and tests.
Description
Source is a transparent disc with diameter 25 mm and height 3 mm. Radionuclide is deposited on active part made of light ceramic pellet. Active part is mounted in center of acrylic capsule and sealed with epoxy resin. Dimensions of active part are 2 mm in diameter and 1 mm in height.
