The Scintillation Probe can measure in units of cps or dose rate. The dose rate response is calibrated against a
nationally traceable caesium-137 source.
The Scintillation Probe dose rate output is designed specifically for the methods of NORM screening required
by North American regulators. General dose rate surveys using the probe are not recommended.
The response of all scintillation detectors vary with radiation energy and the gamma ray energies associated with
caesium-137 are significantly different to those arising from NORM.
