Our hand-, foot-, and cloths-monitor uses 2 scintillator materials. For detection of alpha-radiation, ZnS is applied, for detection of beta and gamma radiation a plastic scintillator foil is used.
The large area detector window is permeable for low energy alpha radiation like Am-241 or beta radiation like C-14.
The thin window can be replaced easily by the user and measurements can be continued without delay. The light flashes generated by the alpha or beta/gamma radiation can be separated by pulse analysis. The detected events are counted over time and displayed digitally in c/s, Bq or Bq/cm2. Nuclide specific sensitivity is calculated and alarm values are pre-programmed.
Measurement results can be stored and transferred by RS 232 C.
