Volumetric Sources — Marinelli beakers are designed for low specific activity measurement. Sources are produced by deposition of precise quantity of the radioactive solution on the cationite granules with density 0.7–1.18 g/cm3 or other materials by customer request. Sources are attested by ISO 17025 certified laboratory and purposed for calibration, validation and test of gamma spectrometers. Volumetric sources are produced in Marinelli beakers from general suppliers (ga-maassociates.com) or in containers provided by end users.
