NEW Model 14C Survey Meter with Pancake GM Probe with Exposure Filter
The Model 14C Survey Meter meets the essential monitoring and surveying needs of most nuclear medicine facilities. The exposure filter flattens the response for energies between 33 keV to 1.2 MeV. For background readings, the unit’s built-in GM detector handles counts up to 2 R/hr. For beta emitters, the pancake probe has approximately twice the counting efficiency as an end-window detector. For high-range gamma detection, the internal detector with the x1000 multiplier range is used.
