100 cm^2 Alpha/Beta Scintillation probe

These hand probes are general purpose survey and frisking probes with excellent sensitivity to alpha with minimum interference from gamma backgrounds. The probe design is constructed from lightweight aluminum which promotes ruggedness and ergonomic handling. This probe can be matched with Thermo’s portable survey meters, such as the ASP-2, E-600, RM-25 or Electra/Delta series.
