G Probe

Microspec Gamma Probes

In the MICROSPEC system, NaI response functions and efficiencies are stored in the on-board computer. The acquired spectrum is stripped and used to calculate dose equivalent using internationally accepted energy-dose conversion coefficients. The result is a NaI-based system that provides highly accurate, energy-independent, tissue equivalent dose.

X-Ray Probe

Microspec X-Ray Probe

The MICROSPEC X-Ray Probe was developed to perform spectral and dose-equivalent measurements for low-energy photons for assessment of radiological hazards for the skin Hp(0.07) and eye Hp(3). The MICROSPEC X-Ray Probe uses a thin NaI crystal, which has low detection efficiency for high-energy gamma rays and high detection efficiency for low-energy gamma rays.
